    1991-03-01

    This report summarizes the progress of the subcontracted photovoltaic (PV) research and development (R D) performed under the Photovoltaics Program at the Solar Energy Research Institute (SERI). The SERI subcontracted PV research and development represents most of the subcontracted R D that is funded by the US Department of Energy (DOE) National Photovoltaics Program. This report covers fiscal year (FY) 1990: October 1, 1989 through September 30, 1990. During FY 1990, the SERI PV program started to implement a new DOE subcontract initiative, entitled the Photovoltaic Manufacturing Technology (PVMaT) Project.'' Excluding (PVMaT) because it was in a start-up phase, in FY 1990 there were 54 subcontracts with a total annualized funding of approximately $11.9 million. Approximately two-thirds of those subcontracts were with universities, at a total funding of over $3.3 million. Cost sharing by industry added another $4.3 million to that $11.9 million of SERI PV subcontracted R D. The six technical sections of this report cover the previously ongoing areas of the subcontracted program: the Amorphous Silicon Research Project, Polycrystalline Thin Films, Crystalline Silicon Materials Research, High-Efficiency Concepts, the New Ideas Program, and the University Participation Program. Technical summaries of each of the subcontracted programs discuss approaches, major accomplishments in FY 1990, and future research directions. Another section introduces the PVMaT project and reports the progress since its inception in FY 1990. Highlights of technology transfer activities are also reported.

  1. Achromatic self-referencing interferometer

    DOE Patents [OSTI]

    Feldman, M.

    1994-04-19

    A self-referencing Mach-Zehnder interferometer is described for accurately measuring laser wavefronts over a broad wavelength range (for example, 600 nm to 900 nm). The apparatus directs a reference portion of an input beam to a reference arm and a measurement portion of the input beam to a measurement arm, recombines the output beams from the reference and measurement arms, and registers the resulting interference pattern ([open quotes]first[close quotes] interferogram) at a first detector. Optionally, subportions of the measurement portion are diverted to second and third detectors, which respectively register intensity and interferogram signals which can be processed to reduce the first interferogram's sensitivity to input noise. The reference arm includes a spatial filter producing a high quality spherical beam from the reference portion, a tilted wedge plate compensating for off-axis aberrations in the spatial filter output, and mirror collimating the radiation transmitted through the tilted wedge plate. The apparatus includes a thermally and mechanically stable baseplate which supports all reference arm optics, or at least the spatial filter, tilted wedge plate, and the collimator. The tilted wedge plate is mounted adjustably with respect to the spatial filter and collimator, so that it can be maintained in an orientation in which it does not introduce significant wave front errors into the beam propagating through the reference arm. The apparatus is polarization insensitive and has an equal path length configuration enabling measurement of radiation from broadband as well as closely spaced laser line sources. 3 figures.

    Broader source: Energy.gov [DOE]

    This is to provide notice that an Acquisition Letter (AL) will be issued addressing the establishment of subcontract review thresholds on M&O contracts. Currently, DEAR 970.4401-1 and 970.4401-2 require Heads of the Contracting Activities (HCAs) to establish thresholds, by subcontract type and dollar level, for the review and approval of proposed subcontracting actions by each M&O contractor under their cognizance. The AL will seek to improve Consent to Subcontract efficiency and to ensure we apply our resources to those subcontract actions that truly pose the most risk. The AL will state that the HCA should determine appropriate tiers for subcontract review thresholds, as a result of a risk assessment. This tiered approach may result in different thresholds being established for different sites as well as different thresholds at a given site, taking into consideration the best interests of DOE and the following factors: approval status of the contractor's purchasing system results of Independent Peer Review Program for Contractors' Purchasing Systems (e.g., PERT results) results of Contractor Balanced Scorecard Self-assessment size, experience, ability, reliability, and organization of the contractor's purchasing function internal controls, procedures, and organizational stature of the contractor's purchasing function subcontract type (fixed price vs. cost reimbursement) degree of competition value nature of the work/complexity whether the subcontract needs special surveillance

    Here, we introduce a new continuous-variable quantum key distribution (CV-QKD) protocol, self-referenced CV-QKD, that eliminates the need for transmission of a high-power local oscillator between the communicating parties. In this protocol, each signal pulse is accompanied by a reference pulse (or a pair of twin reference pulses), used to align Alice’s and Bob’s measurement bases. The method of phase estimation and compensation based on the reference pulse measurement can be viewed as a quantum analog of intradyne detection used in classical coherent communication, which extracts the phase information from the modulated signal. We present a proof-of-principle, fiber-based experimental demonstration ofmore » the protocol and quantify the expected secret key rates by expressing them in terms of experimental parameters. Our analysis of the secret key rate fully takes into account the inherent uncertainty associated with the quantum nature of the reference pulse(s) and quantifies the limit at which the theoretical key rate approaches that of the respective conventional protocol that requires local oscillator transmission. The self-referenced protocol greatly simplifies the hardware required for CV-QKD, especially for potential integrated photonics implementations of transmitters and receivers, with minimum sacrifice of performance.

  12. Subcontracting practices at the Nevada Operations Office and its management and operating contractor

    SciTech Connect (OSTI)

    1996-05-10

    The Department of Energy (Department), Nevada Operations office (Nevada) is responsible for following established policy in obtaining necessary support services through its Contract Management Division. The objective of the audit was to determine whether Nevada and its Management and Operating (M&O) contractors were following Federal and Department policies with regard to directed support service subcontracts. The audit showed that program offices in Nevada and Headquarters were directing the Nevada M&O contractor to award subcontracts to specific companies or individuals. The subcontractors reported either directly to a program office or to a national laboratory. Furthermore, the subcontractors` work products were delivered directly to the requesting program office. The M&O contractor had only administrative responsibility for the subcontracts awarded. This occurred because Nevada had not established adequate internal controls over the process of procuring support service. As a result, the M&O contractor was paid a higher award fee for managing the Department`s contracts and may have incurred additional costs in staffing its procurement office. We recommended that the Manager, Nevada Operations Office, discontinue directed support service subcontracts to its M&O contractor and act to strengthen internal controls over subcontracting. Nevada management partially concurred with the recommendations but did not believe the directed procurements cited in the report were inappropriate. Details of management`s comments and our responses are included in Part III.

    A continuously referenced apparatus for measuring the concentration of a reactive chemical species in solution comprises in combination conduit means for introducing a sample solution, means for introducing one or more reactants into a sample solution, a reaction zone in fluid communication with said conduit means wherein a first chemical reaction occurs between said species and reactants, and a stream separator disposed within the conduit means for separating the sample solution into a sample stream and a reference stream. An enzymatic reactor is disposed in fluid communication with only the sample stream wherein a second reaction takes place between the said reactants, species, and reactor enzymes causing the consumption or production of an indicator species in just the sample stream. Measurement means such as a photometric system are disposed in communication with the sample and reference streams, and the outputs of the measurement means are compared to provide a blanked measurement of the concentration of indicator species. A peristaltic pump is provided to equalize flow through the apparatus by evacuation. The apparatus is particularly suitable for measurement of isoenzymes in body tissues or fluids.

  2. Lessons learned from the EG&G consolidated hazardous waste subcontract and ESH&Q liability assessment process

    Fix, N.J.

    1995-03-01

    Hazardous waste transportation, treatment, recycling, and disposal contracts were first consolidated at the Idaho National Engineering Laboratory in 1992 by EG&G Idaho, Inc. At that time, disposition of Resource, Conservation and Recovery Act hazardous waste, Toxic Substance Control Act waste, Comprehensive Environmental Response, Compensation, and Liability Act hazardous substances and contaminated media, and recyclable hazardous materials was consolidated under five subcontracts. The wastes were generated by five different INEL M&O contractors, under the direction of three different Department of Energy field offices. The consolidated contract reduced the number of facilities handling INEL waste from 27 to 8 qualified treatment, storage, and disposal facilities, with brokers specifically prohibited. This reduced associated transportation costs, amount and cost of contractual paperwork, and environmental liability exposure. EG&G reviewed this approach and proposed a consolidated hazardous waste subcontract be formed for the major EG&G managed DOE sites: INEL, Mound, Rocky Flats, Nevada Test Site, and 10 satellite facilities. After obtaining concurrence from DOE Headquarters, this effort began in March 1992 and was completed with the award of two master task subcontracts in October and November 1993. In addition, the effort included a team to evaluate the apparent awardee`s facilities for environment, safety, health, and quality (ESH&Q) and financial liability status. This report documents the evaluation of the process used to prepare, bid, and award the EG&G consolidated hazardous waste transportation, treatment, recycling, and/or disposal subcontracts and associated ESH&Q and financial liability assessments; document the strengths and weaknesses of the process; and propose improvements that would expedite and enhance the process for other DOE installations that used the process and for the re-bid of the consolidated subcontract, scheduled for 1997.

    2010-06-15

    A new technique for capturing both the amplitude and phase of an optical waveform is presented. This technique can capture signals with many THz of bandwidths in a single shot (e.g., temporal resolution of about 44 fs), or be operated repetitively at a high rate. That is, each temporal window (or frame) is captured single shot, in real time, but the process may be run repeatedly or single-shot. This invention expands upon previous work in temporal imaging by adding heterodyning, which can be self-referenced for improved precision and stability, to convert frequency chirp (the second derivative of phase with respect to time) into a time varying intensity modulation. By also including a variety of possible demultiplexing techniques, this process is scalable to recoding continuous signals.

    The objective of the PV Manufacturing R&D subcontract was to continue to improve AstroPower's technology for manufacturing Silicon-Film* wafers, solar cells, and modules to reduce costs, and increase production yield, throughput, and capacity. As part of the effort, new technology such as the continuous back metallization screen-printing system and the laser scribing system were developed and implemented. Existing processes, such as the silicon nitride antireflection coating system and the fire-through process were optimized. Improvements were made to the statistical process control (SPC) systems of the major manufacturing processes: feedstock preparation, wafer growth, surface etch, diffusion, and the antireflection coating process. These process improvements and improved process control have led to an increase of 5% relative power, and nearly 15% relative improvement in mechanical and visual yield.

    This report describes work done under Phase 3A of the PVMaT project to address problems that are generic to the photovoltaics (PV) industry. Crystalline silicon solar cells were used in the majority of all terrestrial power modules shipped in 1992. Spire`s analysis in Phase 1 of the PVMaT project indicated that the use of thin ({le}200-{mu}m) silicon cells can substantially reduce module manufacturing costs, provided that processing yields remain as high as they are now for processing standard thickness cells. Because present solar cell tabbing and interconnecting processes have unacceptably high yield losses with such thin cells, the objective of this Phase 3A subcontract is to use Spire`s light soldering technology and experience in designing and fabricating solar cell tabbing and interconnecting equipment to develop high yield throughput, fully automated processes for tabbing and interconnecting thin cells.

    Purpose: External beam radiation therapy is currently considered the most common treatment modality for intraocular tumors. Localization of the tumor and efficient compensation of tumor misalignment with respect to the radiation beam are crucial. According to the state of the art procedure, localization of the target volume is indirectly performed by the invasive surgical implantation of radiopaque clips or is limited to positioning the head using stereoscopic radiographies. This work represents a proof-of-concept for direct and noninvasive tumor referencing based on anterior eye topography acquired using optical coherence tomography (OCT). Methods: A prototype of a head-mounted device has been developed for automatic monitoring of tumor position and orientation in the isocentric reference frame for LINAC based treatment of intraocular tumors. Noninvasive tumor referencing is performed with six degrees of freedom based on anterior eye topography acquired using OCT and registration of a statistical eye model. The proposed prototype was tested based on enucleated pig eyes and registration accuracy was measured by comparison of the resulting transformation with tilt and torsion angles manually induced using a custom-made test bench. Results: Validation based on 12 enucleated pig eyes revealed an overall average registration error of 0.26 ± 0.08° in 87 ± 0.7 ms for tilting and 0.52 ± 0.03° in 94 ± 1.4 ms for torsion. Furthermore, dependency of sampling density on mean registration error was quantitatively assessed. Conclusions: The tumor referencing method presented in combination with the statistical eye model introduced in the past has the potential to enable noninvasive treatment and may improve quality, efficacy, and flexibility of external beam radiotherapy of intraocular tumors.

    The goal of the subcontract is to scale up Semprius' novel micro-cell based modules to an annualized rate of 500 kW of receivers and 10 kW of modules, in support of the DOE 2020 Sunshot Initiative goals. The statement of work (SOW) was broken up into two Phases. Phase I was directed towards process development efforts towards addressing fundamental manufacturing metrics such as yield, die per wafer, automation and throughput. Phase II objectives are to scale to an annualized production rate of 500 kW of receivers and 10 kW of modules, while improving cell efficiency, module efficiency and transfer yield. Semprius has met all the technical milestones and deliverables for the contract. All subtasks were completed earlier than expected and the results exceeded the technical targets. In particular, 3J cell efficiency of 41.2% exceeded the target of 38%, module efficiency of 28.3% exceeded the target of 28% and transfer yield of 96.4% exceeds the target of 95%, with all tasks completed well ahead of schedule. Also, devices fabricated from 1st use GaAs substrates and substrates with two re-uses have been shown to be identical.

    The overall mission of the Institute of Energy Conversion is the development of thin film photovoltaic cells, modules, and related manufacturing technology and the education of students and professionals in photovoltaic technology. The objectives of this four-year NREL subcontract are to advance the state of the art and the acceptance of thin film PV modules in the areas of improved technology for thin film deposition, device fabrication, and material and device characterization and modeling, relating to solar cells based on CuInSe{sub 2} and its alloys, on a-Si and its alloys, and on CdTe. In the area of CuInSe{sub 2} and its alloys, EEC researchers have produced CuIn{sub 1-x}GaxSe{sub 2} films by selenization of elemental and alloyed films with H{sub 2}Se and Se vapor and by a wide variety of process variations employing co-evaporation of the elements. Careful design, execution and analysis of these experiments has led to an improved understanding of the reaction chemistry involved, including estimations of the reaction rate constants. Investigation of device fabrication has also included studies of the processing of the Mo, US and ZnO deposition parameters and their influence on device properties. An indication of the success of these procedures was the fabrication of a 15% efficiency CuIn{sub 1-x}GaxSe{sub 2} solar cell.

    This report describes the results of the literature search, interviews, and site visits conducted during the first six months of this subcontract. This survey was conducted to establish a baseline of information about thermal and photothermal degradation of EVA and case history surveys on discoloration (yellowing/browning) of EVA-based encapsulants in fielded flat-plate PV modules. The literature search revealed that EVA will undergo thermolysis of the acetate groups at temperatures of 130{degrees}C to 150{degrees}C and above, leading to formation of double bonds in the backbone of the copolymer. The survey of case histories of EVA-based encapsulant discoloration in fielded modules in the United States revealed that the problem is limited to those areas of the west and southwest that have comparatively high solar insolation and ambient temperature. It is clear that the discoloration problem is not limited to the modules of any one manufacturer. Discoloration in the EVA encapsulant was experienced in fielded modules from all major US module producers.

    This annual report covers the second year of a 3-year NREL subcontract with the University of Toledo that is focused on improvements in efficiency for radio frequency (rf)-sputtered CdS/CdTe solar cells. In earlier work supported by NREL, the University of Toledo established the viability of two new deposition methods for CdS/CdTe solar cells by fabricating cells with efficiencies greater than 10% at air mass (AM) 1.5 on soda lime glass for all-sputtered cells and also for all-laser-deposited cells. Most of the effort has been placed on radio frequency sputtering (RFS) because it was judged to be more economical and more easily scaled to large-area deposition. However, laser physical vapor deposition (LPVD) has remained the method of choice for the deposition of CdCl{sub 2} layers and also for the exploration of new materials such as the ternary alloys including CdS{sub x} Te{sub 1{minus}x} and dopants such as Cu in ZnTe.

The focus for the first year of the PVMaT Phase 2A project is to establish the baseline process capability and optimize the performance of the present machine. This first year`s activities accelerated the advance of Silicon-Film{trademark} manufacturing technology in several ways. First, the project led directly to plans to make an early introduction of a large solar cell product. The successful fabrication of 646-cm{sup 2} wafers and solar cells paved the way for dramatically increasing the power output per solar cell. Second was the establishment of a basis for the design and construction of a 2.4-MW/yr wafer machine. Another important contribution was the determination of the importance of H{sup +} implantation processes for polycrystalline silicon technologies.

    In 1990, the United States Bureau of the Census released detailed geographic base files known as TIGER/Line (Topologically Integrated Geographic Encoding and Referencing) which contain detail on the physical features and census tract boundaries of every county in the United States. The TIGER database is attractive for two reasons. First, it is publicly available through the Bureau of the Census on tape or cd-rom for a minimal fee. Second, it contains 24 billion characters of data which describe geographic features of interest to the Census Bureau such as coastlines, hydrography, transportation networks, political boundaries, etc. Unfortunately, the large TIGER database only provides raw alphanumeric data; no utility software, graphical or otherwise, is included. On the other hand New S, a popular statistical software package by AT T, has easily operated functions that permit advanced graphics in conjunction with data analysis. New S has the ability to plot contours, lines, segments, and points. However, of special interest is the New S function map and its options. Using the map function, which requires polygons as input, census tracts can be quickly selected, plotted, shaded, etc. New S graphics combined with the TIGER database has obvious potential. This paper reports on our efforts to use the TIGER map files with New S, especially to construct census tract maps of counties. While census tract boundaries are inherently polygonal, they are not organized as such in the TIGER database. This conversion of the TIGER line'' format into New S polygon/polyline'' format is one facet of the work reported here. Also we discuss the selection and extraction of auxiliary geographic information from TIGER files for graphical display using New S.

    The high yield potential and attractive chemical composition of Typha make it a particularly viable energy crop. The Minnesota research effort has demonstrated that total annual biomass yields equivalent to 30 dry tonnes/ha (13 tons/acre) are possible in planted stands. This compares with yields of total plant material between 9 and 16 dry tonnes/ha (4 to 7 tons/acre) in a typical Minnesota corn field. At least 50% of the Typha plant is comprised of a belowground rhizome system containing 40% starch and sugar. This high level of easily fermentable carbohydrate makes rhizomes an attractive feedstock for alcohol production. The aboveground portion of the plant is largely cellulose, and although it is not easily fermentable, it can be gasified or burned. This report is organized in a manner that focuses on the evaluation of the management options task. Results from stand management research performed at the University of Minnesota during 1982 and 1983 are integrated with findings from an extensive survey of relevant emergent aquatic plant research and utilization. These results and findings are then arranged in sections dealing with key steps and issues that need to be dealt with in the development of a managed emergent aquatic bio-energy system. A brief section evaluating the current status of rhizome harvesting is also included along with an indexed bibliography of the biology, ecology, and utilization of Typha which was completed with support from this SERI subcontract. 686 references, 11 figures, 17 tables.

    As a result of this work, Evergreen Solar, Inc., is now poised to take String Ribbon technology to new heights. In the ribbon growth area, Project Gemini-the growth of dual ribbons from a single crucible-has reached or exceeded all the manufacturing goals set for it. This project grew from an R&D concept to a production pilot phase and finally to a full production phase, all within the span of this subcontract. A major aspect of the overall effort was the introduction of controls and instrumentation as in-line diagnostic tools. In the ribbon production area, the result has been a 12% increase in yields, a 10% increase in machine uptime, and the flattest ribbon ever grown at Evergreen. In the cell area, advances in process development and robotic handling of Gemini wafers have contributed, along with the advances in crystal growth, to a yield improvement of 6%. Particularly noteworthy in the cell area was the refinement of the no-etch process whereby the as-grown ribbon surface could be controlled sufficiently to allow this process to succeed as well as it has. This process obviates any need for wet chemistry or etching between ribbon growth and diffusion.

    A major effort during this subcontract period has been to evaluate the microcrystalline Si material under development at United Solar Ovonics Corporation (USOC). This material is actually a hydrogenated nanocrystalline form of Si and it will be denoted in this report as nc-Si:H. Second, we continued our studies of the BP Solar high-growth samples. Third, we evaluated amorphous silicon-germanium alloys produced by the hot-wire chemical vapor deposition growth process. This method holds some potential for higher deposition rate Ge alloy materials with good electronic properties. In addition to these three major focus areas, we examined a couple of amorphous germanium (a-Ge:H) samples produced by the ECR method at Iowa State University. Our studies of the electron cyclotron resonance a-Ge:H indicated that the Iowa State a Ge:H material had quite superior electronic properties, both in terms of the drive-level capacitance profiling deduced defect densities, and the transient photocapacitance deduced Urbach energies. Also, we characterized several United Solar a Si:H samples deposited very close to the microcrystalline phase transition. These samples exhibited good electronic properties, with midgap defect densities slightly less than 1 x 1016 cm-3 in the fully light-degraded state.

    The three-year project entitled ?A Metabolomics and Mouse Models Approach to Study Inflammatory and Immune Responses to Radiation? was initiated in September 2009. The overall objectives of this project were to investigate the acute and persistent effects of low dose radiation on T cell lymphocyte function and physiology, as well the contributions of these cells to radiation-induced inflammatory responses. Inflammation after ionizing radiation (IR), even at low doses, may impact a variety of disease processes, including infectious disease, cardiovascular disease, cancer, and other potentially inflammatory disorders. There were three overall specific aims: 1. To investigate acute and persistent effects of low dose radiation on T cell subsets and function; 2. A genetic approach with mouse models to investigate p38 MAPK pathways that are involved in radiation-induced inflammatory signaling; 3. To investigate the effect of radiation quality on the inflammatory response. We have completed the work proposed in these aims. Below are our major accomplishments: ? Our data show that T cells from low dose irradiated animals have lower proliferation potency and cytokine production upon T cell receptor (TCR) stimulation. This effect was observed as early as 4 hours after radiation, and lasted up to two weeks. ? Using our ultraperformance liquid chromatography coupled with highly sensitive time-of-flight mass spectrometry (UPLC-QTOF) metabolomics method, we demonstrated the global changes of metabolites in T cells upon TCR stimulation in a time-dependent pattern. ? We found that the TCR activation induced metabolome changes are remarkably altered in a dose-dependent manner after radiation. At a dose of 0.5 Gy and above, IR mitigated TCR activation induced metabolome changes while at the dose of as low as 0.1Gy IR had a mild stimulatory effect on some of the metabolome changes. ? We revealed the mechanism for how radiation affects T cell activation by showing that the energy

    This report describes advances made during Phase II (November 10, 1992-November 9, 1993) of a three-phase, cost-shared subcontract whose ultimate goal is the demonstration of thin film CuInSe{sub 2} photovoltaic modules prepared by methods adaptable to safe, high yield, high volume manufacturing. At the end of Phase I, EPV became one of the first groups to clear the 10% efficiency barrier for CIS cells prepared by non-H{sub 2}Se selenization. During Phase II a total area efficiency of 12.5% was achieved for a 1 cm{sup 2} cell. The key achievement of Phase II was the production of square foot CIS modules without the use of H{sub 2}Se. This is seen as a crucial step towards the commercialization of CIS. Using a novel interconnect technology, EPV delivered an 8.0% aperture area efficiency mini-module and a 6.2% aperture area efficiency 720 cm{sub 2} module to NREL. On the processing side, advances were made in precursor formation and the selenization profile, both of which contributed to higher quality CIS. The higher band gap quaternary chalcopyrite material CuIn(S{sub x}, Se{sub 1{minus}X}){sub 2} was prepared and 8% cells were fabricated using this material. Device analysis revealed a correlation between long wavelength quantum efficiency and the CIS Cu/In ratio. Temperature dependent studies highlighted the need for high V{sub OC} devices to minimize the impact of the voltage drop at operating temperature. Numerical modeling of module performance was performed in order to identify the correct ZnO sheet resistance for modules. Efforts in Phase III will focus on increase of module efficiency to 9-10%, initiation of an outdoor testing program, preparation of completely uniform CIS plates using second generation selenization equipment, and exploration of alternative precursors for CIS formation.

If the chemical substance is not photoreactive, a photoreactive mixture can be made with a photoreactive dye that has photoreactive properties unique to the mixture. Alternatively, an optically transparent substrate can absorb the substance or the dye/substance mixture.

    Work performed during the course of this subcontract has led to improved CuInSe{sub 2} (CIS) processing techniques and materials resulting in improved solar cell performance (up to 10% active area efficiency) based on a thick conductive evaporated CdS window layer and an indium-tin-oxide transparent conductor. Modeling of the device performance has indicated that an optimal CdS thickness should exist if pinholes occur in the CIS layer (for example, due to adhesion failures) leading to shunts between the CdS and the back contact. Pinholes in the CIS layer have been dramatically reduced by the use of a Cu-Mo two-phase back contact metallization resulting from significant increases in adhesion between the CIS and the back contact. Controlled leaching of the Cu from the back contact apparently contributes to this improvement without degradation of the solar cells. Finally, CIS has been grown epitaxially on GaAs. Preliminary results suggest explanations for the morphology and defect structures of polycrystalline layers used in devices as well as indicating the general mechanism for growth of CIS by vapor phase methods.

    Oxygen-rich asymptotic giant branch (AGB) stars can be intense emitters of SiO (v = 1 and 2, J = 1 → 0) and H{sub 2}O maser lines at 43 and 22 GHz, respectively. Very long baseline interferometry (VLBI) observations of the maser emission provide a unique tool to probe the innermost layers of the circumstellar envelopes in AGB stars. Nevertheless, the difficulties in achieving astrometrically aligned H{sub 2}O and v = 1 and v = 2 SiO maser maps have traditionally limited the physical constraints that can be placed on the SiO maser pumping mechanism. We present phase-referenced simultaneous spectral-line VLBI images for the SiO v = 1 and v = 2, J = 1 → 0, and H{sub 2}O maser emission around the AGB star R LMi, obtained from the Korean VLBI Network (KVN). The simultaneous multi-channel receivers of the KVN offer great possibilities for astrometry in the frequency domain. With this facility, we have produced images with bona fide absolute astrometric registration between high-frequency maser transitions of different species to provide the positions of the H{sub 2}O maser emission and the center of the SiO maser emission, hence reducing the uncertainty in the proper motions for R LMi by an order of magnitude over that from Hipparcos. This is the first successful demonstration of source frequency phase referencing for millimeter VLBI spectral-line observations and also where the ratio between the frequencies is not an integer.

    Given an incomplete (i.e., partially-observed) network, which nodes should we actively probe in order to achieve the highest accuracy for a given network feature? For example, consider a cyber-network administrator who observes only a portion of the network at time t and wants to accurately identify the most important (e.g., highest PageRank) nodes in the complete network. She has a limited budget for probing the network. Of all the nodes she has observed, which should she probe in order to most accurately identify the important nodes? We propose a novel and scalable algorithm, MaxOutProbe, and evaluate it w.r.t. four network features (largest connected component, PageRank, core-periphery, and community detection), five network sampling strategies, and seven network datasets from different domains. Across a range of conditions, MaxOutProbe demonstrates consistently high performance relative to several baseline strategies

  8. Electrolytic hydrogen production infrastructure options evaluation. Final subcontract report

    SciTech Connect (OSTI)

    Thomas, C.E.; Kuhn, I.F. Jr.

    1995-09-01

    Fuel-cell electric vehicles have the potential to provide the range, acceleration, rapid refueling times, and other creature comforts associated with gasoline-powered vehicles, but with virtually no environmental degradation. To achieve this potential, society will have to develop the necessary infrastructure to supply hydrogen to the fuel-cell vehicles. Hydrogen could be stored directly on the vehicle, or it could be derived from methanol or other hydrocarbon fuels by on-board chemical reformation. This infrastructure analysis assumes high-pressure (5,000 psi) hydrogen on-board storage. This study evaluates one approach to providing hydrogen fuel: the electrolysis of water using off-peak electricity. Other contractors at Princeton University and Oak Ridge National Laboratory are investigating the feasibility of producing hydrogen by steam reforming natural gas, probably the least expensive hydrogen infrastructure alternative for large markets. Electrolytic hydrogen is a possible short-term transition strategy to provide relatively inexpensive hydrogen before there are enough fuel-cell vehicles to justify building large natural gas reforming facilities. In this study, the authors estimate the necessary price of off-peak electricity that would make electrolytic hydrogen costs competitive with gasoline on a per-mile basis, assuming that the electrolyzer systems are manufactured in relatively high volumes compared to current production. They then compare this off-peak electricity price goal with actual current utility residential prices across the US.

    1989-11-01

    The research and development described in this document was conducted within the US Department of Energy's Solar Thermal Technology Program. The goal of this program is to advance the engineering and scientific understanding of solar thermal technology and to establish the technology base from which private industry can develop solar thermal power production options for introduction into the competitive energy market. Solar thermal technology concentrates the solar flux using tracking mirrors or lenses onto a receiver where the solar energy is absorbed as heat and converted into electricity or incorporated into products as process heat. The two primary solar thermal technologies, central receivers and distributed receivers, employ various point and line-focus optics to concentrate sunlight. Current central receiver systems use fields of heliostats (two-axes tracking mirrors) to focus the sun's radiant energy onto a single, tower-mounted receiver. Point focus concentrators up to 17 meters in diameter track the sun in two axes and use parabolic dish mirrors or Fresnel lenses to focus radiant energy onto a receiver. Troughs and bowls are line-focus tracking reflectors that concentrate sunlight onto receiver tubes along their focal lines. Concentrating collector modules can be used alone or in a multimodule system. The concentrated radiant energy absorbed by the solar thermal receiver is transported to the conversion process by a circulating working fluid. Receiver temperatures range from 100{degree}C in low-temperature troughs to over 1500{degree}C in dish and central receiver systems. 12 refs., 119 figs., 4 tabs.

  17. Subcontract Report: Final Report on Assessment of Motor Technologies for Traction Drives of Hybrid and Electric Vehicles (Subcontract #4000080341)

    SciTech Connect (OSTI)

    Fezzler, Raymond

    2011-03-01

    Currently, interior permanent magnet (IPM) motors with rare-earth (RE) magnets are almost universally used for hybrid and electric vehicles (EVs) because of their superior properties, particularly power density. However, there is now a distinct possibility of limited supply or very high cost of RE magnets that could make IPM motors unavailable or too expensive. Because development of electric motors is a critical part of the U.S. Department of Energy (DOE) Advanced Power Electronics and Motors activity, DOE needs to determine which options should be investigated and what barriers should be addressed. Therefore, in order to provide a basis for deciding which research topics should be pursued, an assessment of various motor technologies was conducted to determine which, if any, is potentially capable of meeting FreedomCAR 2015 and 2020 targets. Highest priority was given to IPM, surface mounted permanent magnet (SPM), induction, and switched reluctance (SR) motors. Also of interest, but with lesser emphasis, were wheel motors, multiple-rotor motors, motors with external excitation, and several others that emerged from the assessment. Cost and power density (from a design perspective, the power density criterion translates to torque density) are emerging as the two most important properties of motors for traction drives in hybrid and EVs, although efficiency and specific power also are very important. The primary approach for this assessment involved interviews with original equipment manufacturers (OEMs), their suppliers, and other technical experts. For each technology, the following issues were discussed: (1) The current state-of-the-art performance and cost; (2) Recent trends in the technology; (3) Inherent characteristics of the motor - which ones limit the ability of the technology to meet the targets and which ones aid in meeting the target; (4) What research and development (R&D) would be needed to meet the targets; and (5) The potential for the technology to meet the targets. The interviews were supplemented with information from past Oak Ridge National Laboratory (ORNL) reports, previous assessments that were conducted in 2004, and literature on magnet technology. The results of the assessment validated the DOE strategy involving three parallel paths: (1) there is enough of a possibility that RE magnets will continue to be available, either from sources outside China or from increased production in China, that development of IPM motors using RE magnets should be continued with emphasis on meeting the cost target. (2) yet the possibility that RE magnets may become unavailable or too expensive justifies efforts to develop innovative designs for permanent magnet (PM) motors that do not use RE magnets. Possible other magnets that may be substituted for RE magnets include samarium-cobalt (Sm-Co), Alnico, and ferrites. Alternatively, efforts to develop motors that do not use PMs but offer attributes similar to IPM motors also are encouraged. (3) New magnet materials using new alloys or processing techniques that would be less expensive or have comparable or superior properties to existing materials should be developed if possible. IPM motors are by far the most popular choice for hybrid and EVs because of their high power density, specific power, and constant power-speed ratio (CPSR). Performance of these motors is optimized when the strongest possible magnets - i.e., RE neodymium-iron-boron (NdFeB) magnets - are used.

    Claus, R.O.

    1990-12-01

    Two different fiber optic sensors were considered for use in ceramic cross flow filters. The intensity-based sensor was tested with a great degree of success. Even with a computerized data acquisition system, the intensity-based sensor was unable to achieve the resolution of the Fabry-Perot sensor. Another drawback of the intensity sensor is the hysteresis behavior observed over cyclic variation of temperature. We have determined that extrinsic Fabry-Perot fiber optic sensors can be used to measure thermal strains in ceramic cross-flow filters with accuracies of 0.1 {mu}m/m. The single ended approach of the reflective Fabry-Perot sensors is well suited for high thermal strain measurements; the results obtained show that the output of the fiber sensor tracks the temperature changes exactly as expected and shows no noticeable time lag between the measurand and the output signal. Sapphire fibers were manufactured with silica claddings and their spectral attenuation was measured. An intensity based sensor using sapphire fibers was fabricated and its performance calibrated. The success of the Fabry-Perot sensor has proved that such fiber optic sensors are ideally suited for smart structures'' in fossil energy applications. 11 refs., 43 figs.

    The National Ignition Facility (NIF), a 1.8 MJ, 192 laser beam facility, will have anticipated fusion yields of up to 20 MJ from D-T pellets encased in a gold hohlraum target. The energy emitted from the target in the form of x rays, neutrons, target debris kinetic energy, and target shrapnel will be contained in a 5 m. radius spherical target chamber. Various diagnostics will be stationed around the target at varying distances from the target. During each shot, the target will emit x rays that will vaporize nearby target facing surfaces including those of the diagnostics, the target positioner, and other chamber structures. This ablated vapor will be transported throughout the chamber, and will eventually condense and deposit on surfaces in the chamber, including the final optics debris shields. The research at the University of California at Berkeley relates primarily to the NIF chamber dynamics. The key design issues are the ablation of the chamber structures, transport of the vapor through the chamber and the condensation or deposition processes of those vaporized materials. An understanding of these processes is essential in developing a concept for protecting the final optics debris shields from an excessive coating (> 10 {Angstrom}) of target debris and ablated material, thereby prolonging their lifetime between change- outs. At Berkeley, we have studied the physical issues of the ablation process and the effects of varying materials, the condensation process of the vaporized material, and design schemes that can lower the threat posed to the debris shields by these processes. In addition to the work described briefly above, we performed extensive analysis of the target-chamber thermal response to in- chamber CO{sub 2} Cleaning and of work performed to model the behavior of silica vapor. The work completed this year has been published in several papers and a dissertation [1-6]. This report provides a summary of the work completed this year, as well as copies fo presentation materials that have not been published elsewhere. In particular, the Appendix contains copies of presentations made on CO{sub 2} cleaning that are not available elsewhere.

    1995-03-01

    This report describes work performed under a 3-year, 3-phase, cost-share contract to demonstrate significant cost reductions and improvements in manufacturing technology. The objective of the program is to reduce costs in photovoltaic manufacturing by approximately 10% per year. The work was focused in three main areas: (1) silicon crystal growth and thin wafer technology; (2) silicon cell processing; and (3) silicon module fabrication and environmental, safety, and health issues. During this reporting period, several significant improvements were achieved. The crystal growing operation improved significantly with an increase in growth capacity due to larger crucibles, higher polysilicon packing density, and high pull speeds. Wafer processing with wire saws progressed rapidly, and the operation is completely converted to wire saw wafer processing. The wire saws yield almost 50% more wafers per inch in production, thus improving manufacturing volume by 50% without any additional expense in crystal growth. Cell processing improvements focused on better understanding the contact paste and firing processes. Module designs for lower material and labor costs began with the focus on a new junction box, larger modules with larger cells, and a less costly framing technique. In addition, chlorofluorocarbon (CFC) usage was completely eliminated in the Siemens manufacturing facility during this period, resulting in significant reductions in the cost of caustic waste treatment.

The work focused on near-term projects in the SSI (Siemens Solar Industries) Czochralski (Cz) manufacturing facility in Camarillo, CA; the final phase was concentrated in areas of crystal growth, wafer technology, and environmental, safety, and health issues. During this period: (1) The crystal-growing operation improved with increased growth capacity. (2) Wafer processing with wire saws continued to progress; the wire saws yielded almost 50% more wafers per inch in production. The wire saws needs less etching, too. (3) Cell processing improvements focused on better handling and higher mechanical yield. The cell electrical distribution improved with a smaller standard deviation in the distribution. (4) Module designs for lower material and labor costs continued, with focus on a new junction box, larger modules with larger cells, and less costly framing techniques. Two modules demonstrating these cost reductions were delivered during this phase.

    This report summarizes the progress made at ASE Americas Inc. during the first year (Phase I) of the planned 3 year program in Phase 4A2 on the development of technology to address its photovoltaic module manufacturing flexibility and cost reduction for its products. This program focusses on advancing manufacturing technology to reduce the thickness of EFG wafers from 300 to 250 microns, to raise EFG solar cell efficiency to be able to produce cells with average efficiency of 15.5% on 10 cm x 10 cm area wafers, and to simplify processes and reduce costs in interconnect and module manufacturing. This work includes the development of a novel and new environmentally safe and reduced cost diffusion glass removal process for the solar cell manufacturing line. The overall goal of the program is to reduce EFG module manufacturing costs by 25%. Module cost reductions of approximately 7% can be identified as a result of successes on the program in the first year. The work in Phase I has been subdivided into efforts in three areas: Task 1: Wafers, Task 2: Cells, and Task 3: Modules.

    This report describes work performed under a 3-year contract to demonstrate signfficant cost reductions and improvements in manufacturing technology. The work focused an near-term projects for implementation in the Siemens Solar Industries (SSI) Czochralski (CZ) manufacturing facility in Camarillo, California, and was undertaken to increase the commercial viability and volume of photovoltaic manufacturing by evaluating the most significant cost categories and then lowering the cost of each Rem through experimentation, materials refinement, and better industrial engineering. During this reporting period, several significant improvements were achieved. (1) The crystal-growing operation improved with an increase in growth capacity. Higher growing throughput was demonstrated with larger crucibles, higher polysilicon packing density, and higher pull speeds. (2) The operation was completely converted to wire-saw wafer processing. The wire saws yield over 40% more wafers per inch in production. The capacity improvement generated by wire saws increased overall manufacturing volume by more than 40% without additional expenses in cyrstal growth. (3) Cell processing improvements focused on better understanding of the contact paste and firing processes. (4) Module designs for lower material and labor costs began with the focus on a new junction box, larger modules with larger cells, and less costly framing technique. CFC usage was completely eliminated in the SSI manufacturing facility during this phase of the contract.

    This report describes work under Phase II of a Photovoltaic Manufacturing Technology project to conduct laboratory problem definition with an emphasis on controlled aging studies to evaluate the influence of various compositional, processing, and operating parameters on ethylene vinyl acetate (EVA) discoloration. In support of future accelerated UV aging studies (AAS) of coupon-sized EVA laminates, an Atlas xenon arc Ci35A Weather-Ometer was procured, installed, and calibrated for temperature and irradiance. In preparing for the AAS studies, UV-visible spectroscopy measurements were performed on various types of low-iron glass, representive of materials used for module superstrates. It was discovered that the transmission spectra of some of the grades in the UV region from 250 to 400 nm was significantly different. Older grades of Solatex and solite, and StarPhire 'cut off' well below 290 nm, while newer grades of Solatex and Solite, and StarPhire and Airphire greatly reduce the UV transmittance between 280 and 330 nm. Controlled aging studies are presently underway at 0.55 W/m2, 340 nm, and 100 degrees C, and we expect comparative data on yellowing to be available soon.

    2007-09-01

    Utica College, located in Utica New York, intends to install an on-site power/cogeneration facility. The energy facility is to be factory pre-assembled, or pre- assembled in modules, to the fullest extent possible, and ready to install and interconnect at the College with minimal time and engineering needs. External connections will be limited to fuel supply, electrical output, potable makeup water as required and cooling and heat recovery systems. The proposed facility will consist of 4 self-contained, modular Cummins 330kW engine generators with heat recovery systems and the only external connections will be fuel supply, electrical outputs and cooling and heat recovery systems. This project was eventually cancelled due to changing DOE budget priorities, but the project engineers produced this system design specification in hopes that it may be useful in future endeavors.

    Sengupta, D.L.; Senior, T.B.A.; Ferris, J.E.

    1983-01-01

    Electromagnetic interference to television reception caused by small wind turbines (generating about 5 kW of power) has been studied by carrying out measurements using 1/8th-scale models of small windmills in conjunction with a microwave TV system inside an anechoic chamber. Two- and three-bladed windmills with metallized and wooden blades rectangular and trapezoidal in shape were investigated. The locally available TV Channel 9 signal was received and, after up-converting its center frequency to 4.0 GHz, was used as the rf source of the microwave TV system. The television interference (TVI) results were extrapolated to give the TVI effects of the corresponding full-scale windmills at the commercial TV Channel frequencies. Generally, it was found that the two- and three-bladed machines produced similar TVI effects, the metallized blades producing stronger interference than the wooden blades. Extrapolation of the results obtained indicate that, even at the highest TV frequency, the significant TVI effects (video distortion) produced by small wind turbines will not extend out to a distance larger than about 2.5 times the rotor diameter. At lower TV frequenies (or Channel numbers) the distance will be correspondingly smaller. Within this distance, the observed effects will generally be small to negligible over most of the region except possibly in the forward interference direction.

    Sengupta, D L; Senior, T B.A.; Ferris, J E

    1983-01-01

    The electromagnetic interference to television reception caused by the 17 m Darreius at Albuquerque, NM, has been studied by carrying out measurements at a number of sites in the vicinity of the VAWT. The rf sources used were the commercial vhf and uhf TV signals available in the area. Ambient field-strength measurements showed that the signals on all TV channels except one were strong, and provided good reception at all test sites. With the antenna (properly) oriented for maximum direct signal, unacceptable interference was observed on some channels at sites out to 33 m from the WT in the forward and backward regions. With the antenna beam directed at the WT, interference varying from slight to violent were observed at all sites on some or all TV channels. A simple theoretical model has been developed for analyzing the TVI produced by a VAWT like the Darrieus. Using the model in conjunction with measured data, an approximate expression for the equivalent scattering area A of the Darrieus has been developed. It is found that A is wavelength (lambda) dependent and varies as lambda/sup 1/2/.

    2007-07-01

    The goal of this project is to develop and fabricate a 5kW dc-dc converter with a baseline 14V output capability for fuel cell and hybrid vehicles. The major objectives for this dc-dc converter technology are to meet: Higher efficiency (92%); High coolant temperature,e capability (105 C); High reliability (15 Years/150,000miles); Smaller volume (5L); Lower weight (6kg); and Lower cost ($75/kW). The key technical challenge for these converters is the 105 C coolant temperatures. The power switches and magnetics must be designed to sustain these operating temperatures reliably, without a large cost/mass/volume penalty.

    Friedman, P.S.; Parent, C.R.

    1987-04-01

    An investigation of luminescent solar concentrators (LSCs) was begun by the US Department of Energy (DOE) at Owens-Illinois, Inc., in 1978. Experimental and theoretical results of that investigation are summarized in this report. An assessment of the LSC technology was compiled to provide a concise description to guide future research in this field. Since 1978, tremendous progress was made in the development of this device as a practical nonimaging concentrator for achieving solar concentration ratios on the order of 10X. The two most important technical achievements appear to be first, the understanding that dye self-absorption of radiated energy is not as serious a problem as originally thought; and second, the demonstration that organic dyes in polymeric hosts are capable of surviving outdoors in bright sunlight for years without serious degradation. System efficiencies approaching 4% have been achieved for photovoltaic conversion and theoretical efficiencies on the order of 9% appear feasible for large-area devices.

    1988-06-01

    During the FY 1983-84, system analysis studies were performed by the Florida Solar Energy Center and Creare Inc. to assess the economic and technological viability of the OC-OTEC concept for producing both electricity and fresh water on a small scale. A major conclusion of the study was that land-based OC-OTEC plants as small as 10 MWe may be economically feasible in island communities if cost credits are taken for the fresh water produced. The present study builds upon and extends the results of that work. Assess the effect of the seasonal variation in the ocean surface water temperature on the performance of OC-OTEC plants; evaluate the technical feasibility of building small scale OC-OTEC plants using existing low pressure steam turbine rotor designs; refine the plant structure model developed during the Phase I study; and develop background information and analyses to evaluate the various alternative strategies for handling noncondensible gases in OC-OTEC plants. Refinements in OC-OTEC plant performance and cost models performed during the present study have reduced the estimated cost of a 10 MW baseline plant from 99 to 72M$. Further cost reduction of 5 to 10M$ is anticipated from the revised structure cost model and the implementation of barometric leg deaeration and hydraulic compression. Therefore, the results from this study reinforce the earlier conclusion that small-scale OC-OTEC plants are competitive at present for the production of electricity and fresh water in the Caribbean and Pacific Islands. OC-OTEC represents a technology with significant potential. We recommend that it be aggressively pursued. 33 refs., 67 figs., 20 tabs.

    2004-06-01

    This project developed the process technologies for the fabrication of high-efficiency multijunction photovoltaic cells using semiconductor nanostructure arrays. These devices are expected to provide increased energy conversion efficiency, as well as increased carrier collection efficiency. In addition, this approach provides the ability to tune the absorption spectrum to match selected windows of the solar spectrum. At the same time, these devices can be fabricated using existing industrial electrochemical processing techniques that can substantially reduce the cost of each device. The fabrication technique is based on electrochemical synthesis of II-VI semiconductor quantum wires using a preformed alumina template. This project focused on and solved the technical challenges that need to be addressed for the implementation of such devices. Specific issues addressed include (a) improved pore ordering on thin-film templates, (b) synthesis of II-VI semiconductor nanostructures by both AC and DC deposition, (c) an in-situ barrier-layer engineering process that allow the fabrication of superior-quality materials and improved template/substrate interface, (d) characterization techniques for templates, (e) process technology for creating stacked layers of nanostructures, (f) process throughput and improved apparatus, (g) modeling tools, (h) use of glass substrates, and (i) a nonlithographic surface texturing technique for silicon PV cells. An important outcome of this project is the demonstration of the fabrication technique on glass substrates. This breakthrough provides the possibility of covering buildings with''transparent'' solar cells fabricated on architectural glass. The accomplishments of this project position it well for the next phase of research, namely, creation and optimization of the nanostructure-based PV cells.

    Executive Summary The funding provided by the DOE for this project was used exclusively to purchase research equipment involved with the field development and evaluation of crop production technologies and practices for energy crop production. The new equipment has been placed into service on the SIU farms and has significantly enhanced our research capacity and scope for agronomy and precision ag research to support novel seed traits or crop management strategies for improving the efficiency and productivity of corn and soybeans. More specifically, the precision ag capability of the equipment that was purchased has heightened interest by faculty and associated industry partners to develop collaborative projects. In addition, this equipment has provided SIU with a foundation to be more successful at securing competitive grants in energy crop production and precision ag data management. Furthermore, the enhanced capacity for agronomy research in the southern Illinois region has been realized and will benefit crop producers in this region by learning to improve their operations from our research outcomes.

    The goal of this project, sponsored by Agri-Tech Producers, LLC (ATP), the small business grantee, was to determine if the torrefaction technology, developed by North Carolina State University (NCSU), which ATP has licensed, could be feasibly deployed in a mobile unit. The study adds to the area investigated, by having ATP’s STTR Phase I team give thoughtful consideration to how to use NCSU’s technology in a mobile unit. The findings by ATP’s team were that NCSU’s technology would best perform in units 30’ by 80’ (See Spec Sheet for the Torre-Tech 5.0 Unit in the Appendix) and the technical effectiveness and economic feasibility investigation suggested that such units were not easily, efficiently or safely utilized in a forest or farm setting. (Note rendering of possible mobile system in the Appendix) Therefore, the findings by ATP’s team were that NCSU’s technology could not feasibly be deployed as a mobile unit.

    The Odderon, a charge-conjugation-odd partner of the Pomeron, has been a puzzle ever since its introduction in 1973. The Pomeron describes a colorless exchange with vacuum quantum numbers in the t-channel of hadronic scattering at high energies. The concept was originally formulated for the non-perturbative regime of Quantum Chromodynamics (QCD). In perturbation theory, the simplest picture of the Poineron is that of a two-gluon exchange process, whereas an Odderon can be thought of as an exchange of three gluons. Both the Pomeron and the Odderon are expected in QCD. However, while there exists plenty of experimental data that could be successfully described by Pomeron exchanges (for example in electron-proton and hadron-hadron scattering at high energies), no experimental sign of the Odderon has been observed. One of the very few hints so far is the difference in the diffractive minima of elastic proton-proton and proton-antiproton scattering measured at the ISR. The Odderon has recently received renewed attention by QCD researchers, mainly for the following two reasons. First of all, RHIC has entered the scene, offering exciting unique new opportunities for Odderon searches. RHIC provides collisions of nuclei at center-of-mass energies far exceeding those at all previous experiments. RHIC also provides collisions of protons of the highest center-of-mass energy, and in the interval, which has not been explored previously in p {bar p} collisions. In addition, it also has the unique feature of polarization for the proton beams, promising to become a crucial tool in Odderon searches. Indeed, theorists have proposed possible signatures of the Odderon in some spin asymmetries measurable at RHIC. Qualitatively unique signals should be seen in these observables if the Odderon coupling is large. Secondly, the Odderon has recently been shown to naturally emerge from the Color Glass Condensate (CGC), a theory for the high-energy asymptotics of QCD. It has been argued that saturation/CGC effects tend to decrease the Odderon intercept, possibly providing an explanation for the lack of experimental evidence for the Odderon so far. This has added further motivation for pursuing searches for the Odderon. During the workshop the status of the Odderon in QCD and its phenomenology were reviewed. The participants also agreed on the most promising observables for the Odderon search at RHIC, which we list. The conclusion of the workshop is that the best available setup to address experimental questions related to the search for the Odderon at RHIC is the proposed combination of STAR experiment and Roman pots of pp2pp experiment, described in the proposal ''Physics with Tagged Forward Protons with the STAR detector at RHIC''.

    Wilbur, Daniel Scott

    2012-12-12

    Alpha-particle emitting radionuclides hold great promise in the therapy of cancer, but few alpha-emitters are available to investigators to evaluate. Of the alpha-emitters that have properties amenable for use in humans, 211At is of particular interest as it does not have alpha-emitting daughter radionuclides. Thus, there is a high interest in having a source of 211At for sale to investigators in the US. Production of 211At is accomplished on a cyclotron using an alpha-particle beam irradiation of bismuth metal. Unfortunately, there are few cyclotrons available that can produce an alpha particle beam for that production. The University of Washington has a cyclotron, one of three in the U.S., that is currently producing 211At. In the proposed studies, the things necessary for production and shipment of 211At to other investigators will be put into place at UW. Of major importance is the efficient production and isolation of 211At in a form that can be readily used by other investigators. In the studies, production of 211At on the UW cyclotron will be optimized by determining the best beam energy and the highest beam current to maximize 211At production. As it would be very difficult for most investigators to isolate the 211At from the irradiated target, the 211At-isolation process will be optimized and automated to more safely and efficiently obtain the 211At for shipment. Additional tasks to make the 211At available for distribution include obtaining appropriate shipping vials and containers, putting into place the requisite standard operating procedures for Radiation Safety compliance at the levels of 211At activity to be produced / shipped, and working with the Department of Energy, Isotope Development and Production for Research and Applications Program, to take orders, make shipments and be reimbursed for costs of production and shipment.

    Johnson, C W

    2012-01-24

    The project period was devoted to several developments in the technical capabilities of the BIGSTIC large-dimension configuration-interaction shell-model code, written in Fortran 90. The specific computational goals for the project period were: (1) store Lanczos vectors on core in RAM to minimize I/O; (2) rewrite reorthogonalization with Lanczos vectors stored in core, consult with personnel at LLNL, LBL, ORNL, Iowa State University to maximize performance; (3) restrict creation of N-body jumps to those needed by an individual node; and (4) distribute 3-body interaction over many cores. Significant progress was made towards these goals, especially (1) and (2), although in the process they discovered intermediate tasks that had to be accomplished first. The achievements were as follows - I put into place structures and algorithms to facility fragmenting very large-dimension Lanczos intermediate vectors. Only by fragmenting the vectors can we carry out (1) and (2). In addition, I reorganized the action of the Hamiltonian matrix and created a new division of operations for MPI. Based upon earlier work, I made plans of a revised algorithm for distribution of work with MPI, with a particular eye towards breaking up the Lanczos vectors. I introduce a new derived type (opbundles) which collects the parameters for the Hamiltonian, and rewrote the application routines to use it. It has been validated and verified. I made progress towards revised MPI parallelization. Using the opbundles, I was able to compute a distribution of work over compute nodes, which should be very efficient. This new distribution is easier to derive and more efficient, in principle, than the old distribution. Furthermore, it should make applications with fragmented Lanczos vectors easier. Implementation is still in progress.

    MicroLink has developed a process technology that will enable the manufacture of high-efficiency, low-cost, multijunction solar cells for use in concentrating photovoltaic (CPV) applications. The multijunction cells were fabricated using a novel low-temperature wafer bonding process. A triple-junction InGaP/GaAs/Ge tandem solar cell with efficiency of 30% at 1 sun AM1.5 illumination was fabricated by wafer bonding a dual-junction InGaP/GaAs cell to a single-junction Ge cell. Temperature cycling over the range -25 degrees C to +40 degrees C resulted in no degradation of cell performance. Triple junction InGaP/GaAs/Ge cells were mounted onto ceramic carriers and tested at concentrations up to 300 suns.

    This report describes results from the first phase of a three-phase contract for the development of stable, high-efficiency, same-band-gap, amorphous silicon (a-Si) multijunction photovoltaic (PV) modules. The program involved improving the properties of individual layers of semiconductor and non-semiconductor materials and small-area single-junction and multijunction devices, as well as the multijunction modules. The semiconductor materials research was performed on a-Si p, i, and n layers, and on microcrystalline silicon n layers. These were deposited using plasma-enhanced chemical vapor deposition. The non-semiconductor materials studied were tin oxide, for use as a transparent-conducting-oxide (TCO), and zinc oxide, for use as a back reflector and as a buffer layer between the TCO and the semiconductor layers. Tin oxide was deposited using atmospheric-pressure chemical vapor deposition. Zinc oxide was deposited using magnetron sputtering. The research indicated that the major challenge in the fabrication of a-Si multijunction PV modules is the contact between the two p-i-n cells. A structure that has low optical absorption but that also facilitates the recombination of electrons from the first p-i-n structure with holes from the second p-i-n structure is required. Non-semiconductor layers and a-Si semiconductor layers were tested without achieving the desired result.

    The Solar America Initiative (SAI) is intended to provide numerous technological routes towards a lower levelized cost of solar-generated electricity (LCOE). MicroLink's planned contribution towards the SAI is to provide a method of lowering the cost of GaAs-based solar cells, which are a major contributor to the cost of concentrator photovoltaic (CPV) modules. MicroLink's unique approach is to use an epitaxial liftoff (ELO) process to completely remove the active solar cell from the substrate while preserving the performance and yield of the cell. The substrate accounts for approximately half the cost of conventional, multijunction GaAs-based solar cells. By using ELO, the substrate can be reused several times for additional solar cell growths, thereby reducing the cost of multijunction solar cells by up to 50%. The achievement of high efficiency has significantly increased the acceptance of MicroLink Devices as a future supplier of high-efficiency dual-junction and IMM (inverted metamorphic) triple-junction ELO solar cells. MicroLink entered the SAI program with a 10% efficiency GaAs solar cell (1-sun AM 1.5) and finished the program with an NREL-verified IMM triple-junction ELO solar cell (1-sun AM 1.5).

    This report describes work to develop an advanced, low-cost manufacturing process for a now utility-scale, flat-plate module. This process starts with the production of continuous sheets of thin-film, polycrystalline silicon using the Silicon-Film{trademark} process. Sheets are cut into wafers that are nominally 15 cm on a side. Fifty-six of these wafers are then fabricated into solar cells that are strung together into a 170-W module. Twelve of these modules form a 2-kW array. The program has three main components: (1) development of a Silicon-Film{trademark} wafer machine that is capable of manufacturing waters that are 225 cm{sup 2} in size at a rate of 3.0 MW/yr, with a total product cost reduction of 70%; (2) development of an advanced solar cell manufacturing process that is capable of turning the Silicon-Film{trademark} wafer into a 3.25-W solar cell; and (3) development of an advanced module design based on these large-area silicon solar cells with an average power of 170 W for 56 solar cells and 113 W for 36 solar cells.

Productivity improvements of the Silicon-Film{trademark} machine were accomplished during the second phase. Improvements were made in solar cell performance while decreasing materials consumption, integrating and mechanizing the fabrication process for solar cells, and scaling-up solar cell and module equipment for fabricating larger cells. AstroPower is continuing work on separating out effects due to impurities and effects due to defects. Analytical tools were developed for measuring area-based response based on EBIC and LBIC methods. The Kauffman source for hydrogen ion implantation was used to map out the process space for Silicon-Film{trademark} solar cell improvement. Progress was made on improving short-circuit current. Areas of focus include developing tools to quickly assess material quality; developing a hydrogen implantation process; increasing material quality on large-area, high-throughput wafers; and studying potential processes for improving solar cell power output during cell fabrication. A method to improve current collection in a solar cell after contact formation is under development.

    The goal of this project is to develop an advanced, low-cost manufacturing process for a new utility-scale, flat-plate module. The program has three main components: development of a Silicon-Film{trademark} (S-F) wafer machine that is capable of manufacturing wafers that are 225 cm{sup 2} in size with a total product cost reduction of 70%; development of an advanced solar cell manufacturing process that is capable of turning the wafer into a 14% efficient solar cell; and development of an advanced module design based on these large area, efficient silicon solar cells with an average power of 170 watts for 56 solar cells and 113 watts for 36 solar cells. During Phase 2, AstroPower made significant advances in improving S-F material quality and device performance. Advances were made in developing the prototype machines and processes toward reliable manufacturing counterparts. The following key achievements in Phase 2 are detailed: demonstration of a truly continuous production mode S-F machine; demonstration of a 2.5 watt, 15 cm by 15 cm solar cell; and demonstration of a 78 watt module fabricated from 36, 15 cm by 15 cm S-F solar cells.

    The goal of AstroPower`s PVMaT-2A project is to develop an advanced, low-cost manufacturing process for a new utility-scale, flat-plate module. This process starts with the production of continuous sheets of thin-film polycrystalline silicon using the Silicon-Film {trademark} process. Our main product focus in PVMaT-2A has been a 240 cm{sup 2} solar cell. Continuous sheets of silicon are produced and cut into wafers that are 15.5 cm on a side. Both standard modules (36 solar cells) and a new 56 solar cell module were produced. The targeted high power module design is a 170 watt module, used in a twelve module array to generate 2 kW. The solar cells, modules, and array developed here are described.

    To reduce the numbers of avian collisions with wind turbines, several measures have been employed with various levels of success. One hypothesis is that painting turbine blades to increase their visibility may reduce avian fatalities. This study examined the effects of painting wind turbine blades with UV-reflective paint on bird use and mortality at the Foote Creek Rim Wind Plant in Carbon County, Wyoming.

    Work was sperformed to determine effects of methanol fuel on engine performance and exhaust emissions during long-term use in a 1988 Chevrolet Corsica. Engine wear, gasket performance, fuel economy, emissions level, oil consumption, and overall vehicle performance were monitored over 22,000 miles. Baselines were established at the beginning for comparison: engine was disassembled, bearing/ring clearances and cam profiles were measured. Higher flow rate fuel injectors from AC Rochester were installed and the computer system calibrated for M100 fuel. The vehicle durability test increased oil consumption by 26% under cold-start conditions, 9% under hot start. Oil consumption under hot start was higher than under cold start by as much as 56%; effect of component temperatures on oil viscosity appears to be the cause. It is recommended that oil consumption of a gasoline-fueled vehicle be measured in order to normalize the effect of methanol operation on oil consumption, and to study the effect of steady-state and transient conditions on oil consumption.

    1993-08-01

    This report describes work to test the feasibility of a new solar cell concept -- the epitaxial optical reflector (EOR) solar cell. This cell concept alters current designs for high efficiency cells by changing the optical absorption efficiency of single cells. The change is introduced by the use an epitaxial multilayer reflector as an integral part of the cell to increase the optical path length of certain wavelengths of light in the cell. These changes are expected to increase the open circuit voltage at which power is extracted from the cell. The program is designed to test the feasibility of the use of a broad band epitaxial multilayer reflector grown as an integral part of the device structure to reflect the near-band-edge light back through the device for a second absorption pass. This second pass allows the design of a solar cell with a thinner base, and the use of the epitaxial reflector as a heterojunction carrier-reflecting barrier at the rear of the device. The thinner cell design and altered carrier profile that results from the light- and carrier-reflecting barrier will decrease the carrier concentration gradient and increase the open circuit voltage. The program is structured to have three tasks: (1) Solar Cell and Reflector Modeling, (2) Materials Growth and Optimization, and (3) Solar Cell Fabrication and Characterization.

    The designs and systems developed include many innovative concepts and experiments, including the design and operation of a low-cost system. Cost-effectiveness is realized by minimizing capital costs of the system and achieving efficient use of inputs. Extensive engineering analysis of carbonation, mixing, and harvesting subsystems has elucidated both the lowest cost, most efficient options and the essential parameters needed to construct, test, and evaluate these subsystems. The use of growth ponds sealed with clay and lined with crushed rock results in construction cost savings of 50% over ponds lined with synthetic membranes. In addition a low-cost but efficient design allows improvements in technology to have maximum impact on final product cost reductions. In addition to the innovations in low-cost construction, the operational efficiency of the design is both higher and more feasible than that attained by any previous system concept of comparable scale. The water analysis has led to operational specifications that minimize water use and virtually eliminate losses of carbon dioxide to the atmosphere. The carbon dioxide injection system is designed for 95% efficiency, but is still low in cost. The construction of a large-scale, covered anaerobic lagoon to recycle carbon, nitrogen, and phosphorus has not been attempted at the scale analyzed here. Yet efficient recycling is essential for achieving economic affordability. 23 refs., 21 figs., 53 tabs.

    Transparent and reflecting electrodes are important parts of the structure of amorphous silicon solar cells. We report improved methods for depositing zinc oxide, deposition of tin nitride as a potential reflection-enhancing diffusion barrier between the a-Si and back metal electrodes. Highly conductive and transparent fluorine-doped zinc oxide was successfully produced on small areas by atmospheric pressure CVD from a less hazardous zinc precursor, zinc acetylacetonate. The optical properties measured for tin nitride showed that the back-reflection would be decreased if tin nitride were used instead of zinc oxide as a barrier layer over silver on aluminum. Niobium-doped titanium dioxide was produced with high enough electrical conductivity so that normal voltages and fill factors were obtained for a-Si cells made on it.

    This report summarizes work performed by Science Applications International Corporation (SAIC) in fulfillment of a contract with the National Renewable Energy Laboratory. The work described here is a continuation of work performed on an earlier contract (YAR-5-15005-01). The goal of the work has been to demonstrate that it is possible to produce a durable low-cost reflector for solar-thermal-electric power systems. The core technology is a technique called ion-beam-assisted physical vapor deposition to produce a silvered reflector with a protective alumina coating. In the previous contract, SAIC optimized the coating process for batch coating. In this contract, we transitioned the coating process from batch coating to roll coating. In the course of the contract, we successfully designed and built a laboratory-scale web handling machine; integrated the machine into the existing SAIC coating chamber; and roll-coated material using an alumina deposition rate as high as 20 nm/s. For a set of optimized parameters, the reflective material was highly reflective and well adhered.

    This report provides an overview of current and developing technologies and techniques for performing geotechnical investigations for siting and designing Cold Water Pipes (CWP) for shelf-resting Ocean Thermal Energy Conversion (OTEC) power plants. The geotechnical in situ tools used to measure the required parameters and the equipment/systems used to deploy these tools are identified. The capabilities of these geotechnical tools and deployment systems are compared to the data requirements for the CWP foundation/anchor design, and shortfalls are identified. For the last phase of geotechnical data gathering for design, a drillship will be required to perform soil boring work, to obtain required high-quality sediment samples for laboratory dynamic testing, and to perform deep-penetration in situ tests. To remedy shortfalls and to reduce the future OTEC CWP geotechnical survey costs, it is recommended that a seafloor-resting machine be developed to advance the friction cone penetrometer, and also probably a pressuremeter, to provide geotechnical parameters to shallow subseafloor penetrations on slopes of 35/degree/ and in water depths to 1300 m. 74 refs., 19 figs., 6 tabs.

The goal for this program is to demonstrate stabilized module efficiency of 12% for multijunction modules of area greater than 900 cm{sup 2}. Double-junction and triple-junction cells are made on Ag/ZnO back reflector deposited on stainless steel substrates. The top cell uses a-Si alloy; a-SiGe alloy is used for the i layer in the middle and the bottom cells. After evaporation of antireflection coating, silver grids and bus bars are put on the top surface, and the panel is encapsulated in an ethylene vinyl acetate (EVA)/Tefzel structure to make a one-square-foot monolithic module.

    Our work consists of hydrogenating silicon (Si) samples by different methods such as low-energy implantation, electron cyclotron resonance (ECR) plasma, and thermal diffusion. The samples will be provided through NREL. The experimental work carried out at Penn State involves the study of hydrogen interaction with defects, trapping, migration, and formation of complexes. The principal vehicle for the latter study will be ion implantation, and the intent is to understand mechanisms of defect passivation and activation by hydrogen. The theoretical studies will consist of the calculation of the structure and parameters related to hydrogen diffusion and interactions of hydrogen with transition metal impurities in silicon. Experimental studies will involve measurements of hydrogen and hydrogen-impurity complexes, and diffusion properties of various species of hydrogen in Si. The experimental work at Penn State includes introduction of hydrogen in a variety of photovoltaic Si by ECR plasma, low-energy ion implantation, and thermal diffusion. The specific tasks will be the evaluation of hydrogen interaction with defects engineered by ion implantation; defect passivation, activation, and migration in hydrogenated Si under thermal anneal; and electrical activity of hydrogen-impurity complexes. Electrical characterization will entail I-V and C-V measurements, spreading resistance, and deep-level transient spectroscopy.

    We became interested in developing new methods for hydrodefluorination (HDF) and other types of C-F bond conversion in polyfluoroalkanes under mild conditions. We were attracted to an approach to C-F activation, where the key C-F cleavage proceeds by a Lewis acid abstraction of fluoride rather than a redox event. The efforts during the previous period were aimed at a) advancing the HDF reactivity with improvement in scope and catalyst longevity; b) extending C-F activation beyond HDF; c) generating insight about the elementary steps of the reaction and potential intermediates.

    The interpretation of relativistic heavy-ion collisions at RHIC energies with thermal concepts is largely based on the relative success of ideal (nondissipative) hydrodynamics. This approach can describe basic observables at RHIC, such as particle spectra and momentum anisotropies, fairly well. On the other hand, recent theoretical efforts indicate that dissipation can play a significant role. Ideally viscous hydrodynamic simulations would extract, if not only the equation of state, but also transport coefficients from RHIC data. There has been a lot of progress with solving relativistic viscous hydrodynamics. There are already large uncertainties in ideal hydrodynamics calculations, e.g., uncertainties associated with initial conditions, freezeout, and the simplified equations of state typically utilized. One of the most sensitive observables to the equation of state is the baryon momentum anisotropy, which is also affected by freezeout assumptions. Up-to-date results from lattice quantum chromodynamics on the transition temperature and equation of state with realistic quark masses are currently available. However, these have not yet been incorporated into the hydrodynamic calculations. Therefore, the RBRC workshop 'Hydrodynamics in Heavy Ion Collisions and QCD Equation of State' aimed at getting a better understanding of the theoretical frameworks for dissipation and near-equilibrium dynamics in heavy-ion collisions. The topics discussed during the workshop included techniques to solve the dynamical equations and examine the role of initial conditions and decoupling, as well as the role of the equation of state and transport coefficients in current simulations.

    In this project, developed scheduling frameworks for dynamic bandwidth demands for large-scale science applications. In particular, we developed scheduling algorithms for dynamic bandwidth demands in this project. Apart from theoretical approaches such as Integer Linear Programming, Tabu Search and Genetic Algorithm heuristics, we have utilized practical data from ESnet OSCARS project (from our DOE lab partners) to conduct realistic simulations of our approaches. We have disseminated our work through conference paper presentations and journal papers and a book chapter. In this project we addressed the problem of scheduling of lightpaths over optical wavelength division multiplexed (WDM) networks. We published several conference papers and journal papers on this topic. We also addressed the problems of joint allocation of computing, storage and networking resources in Grid/Cloud networks and proposed energy-efficient mechanisms for operatin optical WDM networks.

    Under the scope of the ventilation stack study, 1/3 scale models of the TA-55 facility FE- 15 and FE-16 stacks were fabricated and tested. Tests were conducted to achieve stack and plenum configurations that would produce adequate mixing, flow uniformity and particulate concentration uniformity. This should enable effective single point sampling in these exhaust stacks at the existing sampling locations during normal and emergency operating conditions. Velocity profiles were obtained at the current sampling location. Flow mixing was evaluated via a tracer gas technique. Gas concentration profiles were measured with the help of the tracer gas technique while releasing the tracer gas in the different inlet ducts. Finally, aerosol particle concentration profiles were measured at the existing sampling locations. The results indicated that the present field configurations of the two stacks produced poor mixing. Adjustments and modifications of the model configurations were carried out to arrive at uniform velocity, gas and aerosol particle concentrations profiles at the present sampling location. The modified models typically produced profile coefficients of variations that were less than 10%, suggesting that the present sampling locations could effectively be used for single-point sampling. The filter air sampler research is concerned with the development of a filter air sampler to ease filter changing efficiency and to provide a built in flow indicator. Testing was done on the new sampler to find the effect on the entrance efficiency by variations in the parameter-air speed, particle size, flow rate, and orientations. It was found that the aerosol sampling efficiencies of the new unit are no different from the filter air sampler currently used by Los Alamos National Laboratory.

    This report describes a 3-year, cost-shared research program at Solarex to develop all pertinent processes and technologies required to achieve the goal of 12% CIS submodule (with areas > 900 cm{sup 2}). The work is focused on four tasks: (1) window layers, contacts, substrate; (2) CIS absorber layer; (3) device structure; and (4) submodule design and encapsulation. Each task addresses (1) basic material improvements, (2) fabrication and characterization of CIS solar cells, and (3) scale up of processes to large-area substrates.

    This report describes work to develop Silicon-Film{trademark} Product III into a low-cost, stable solar cell for large-scale terrestrial power applications. The Product III structure is a thin (< 100-{mu}m) polycrystalline layer of silicon on a durable, insulating, ceramic substrate. The insulating substrate allows the silicon layer to be isolated and metallized to form a monolithically interconnected array of solar cells. High efficiency is achievable with the use of light trapping and a passivated back surface. The long-term goal for the product is a 1200-cm{sup 2}, 18%-efficient, monolithic array. The short-term objectives are to improve material quality and to fabricate 100 cm{sup 2} monolithically interconnected solar cell arrays. Low minority-carrier diffusion length in the silicon film and series resistance in the interconnected device structure are presently limiting device performance. Material quality is continually improving through reduced impurity contamination. Metallization schemes, such as a solder-dipped interconnection process, have been developed that will allow low-cost production processing and minimize R{sub s} effects. Test data for a nine-cell device (16 cm{sup 2}) indicated a V{sub oc} of 3.72 V. These first-reported monolithically interconnected multicrystalline silicon-on-ceramic devices show low shunt conductance (< 0.1 mA/cm{sup 2}) due to limited conduction through the ceramic and no process-related metallization shunts.

    The objective of this program is to develop Silicon Film{trademark} Product III into a low-cost, stable solar cell for large-scale terrestrial power applications. The Product III structure is a thin (<100 {mu}m) polycrystalline layer of silicon on a durable, insulating, ceramic substrate. The insulating substrate allows the silicon layer to be isolated and metallized to form a monolithically interconnected array of solar cells. High efficiency is achieved by the use of light trapping and passivated surfaces. This project focused on the development of five key technologies associated with the monolithic sub-module device structure: (1) development of the film deposition and growth processes; (2) development of the low-cost ceramic substrate; (3) development of a metallurgical barrier technology; (4) development of sub-element solar cell processing techniques; and (5) development of sub-module (isolation and interconnection) processes. This report covers the development approaches and results relating to these technologies. Significant progress has been made in the development of all of the related technologies. This is evidenced by the fabrication of a working 12.0 cm{sup 2} prototype sub-module consisting of 7 elements and testing with an open circuit voltage of 3.9 volts, a short circuit current of 35.2 mA and a fill factor of 63% and an overall efficiency of 7.3%. Another significant result achieved is a 13.4% (NREL verified), 1.0 cm{sup 2} solar cell fabricated from material deposited and grown on a graphite cloth substrate. The significant technological hurdle of the program was and remains the low quality of the photovoltaic layer which is caused by contamination of the photovoltaic layer from the low-cost ceramic substrate by trace impurities found in the substrate precursor materials. The ceramic substrate and metallurgical barrier are being developed specifically to solve this problem.

    This report highlights the progress made by Solar Cells, Inc. (SCI), in its program to produce 60-cm {times} 120-cm solar modules based on CdTe films. During the past year, confirmed efficiency has increased to 10.4% (active area) on a 1 cm{sup 2} cell, 9.8% (aperture area) on a 64-cm{sup 2} 8-cell submodule, and 6.6% (total area) on a 7200-cm{sup 2} module. A module measured in-house had a power output of 53 W, for a total-area efficiency of 7.4%. Average efficiency of modules produced is steadily increasing and standard deviation is decreasing; in a limited run of 12 modules, results were 6.3% ({plus_minus} 0.2%). Field testing has begun; a nominal 1-kW array of 24 modules was set up adjacent to SCI`s facilities. Analysis indicates that present modules are limited in efficiency by shunt resistance and optical absorption losses in the glass superstrate. Loss analysis of present devices allows us to project a module efficiency of 11.8%. A third generation deposition method -- atmospheric pressure elemental vapor deposition (APEVD) has been brought on-line and has produced good quality CdTe. In addition, SCI is expanding its proactive safety, health, environmental, and disposal program dealing with issues surrounding cadmium.

    This report describes research in Rapid Thermal Processing (RTP), a process that allows the formation of CuInSe{sub 2} without the use of H{sub 2}Se. RTP is a well-established method of rapidly achieving temperatures necessary to melt and recrystallize materials such as Si and and silicides. RTP processes can rapidly and uniformly heat large surface areas to hundreds of degrees Celsius. RTP is the most promising method of rapid recrystallization studied to date, being readily scalable from the research to the production level. The approach to the experiment was divided into two sections: (1) fabricating the precursor film and (2) processing the precursor film. The objective of the first phase of the work was to fabricate the thin films by RTP, then fully characterize them, to demonstrate the viability of the process as a method by which to make device-quality CuInSe{sub 2}. The second phase was to demonstrate that material made by this method could be used to make an active photovoltaic device. 24 refs.

    This report describes work to develop technology to deposit GaAs on Si using a nucleation layer of atomic-layer-epitaxy-grown GaAs or AlAs on Si. This ensures two-dimensional nucleation and should lead to fewer defects in the final GaAs layer. As an alternative, we also developed technology for depositing GaAs on sawtooth-patterned Si. Preliminary studies showed that this material can have a very low defect density, {approximately} 1 {times} 10{sup 5} cm{sup {minus}5}, as opposed to our conventionally grown GaAs on SL which has a typical defect density of over 1 {times}10{sup 7} cm{sup {minus}2}. Using these two now methods of GaAs-on-Si material growth, we made solar cells that are expected to show higher efficiencies than those of previous cells.

    This report describes investigation into the theory and technology of a novel heterojunction or superlattice, single-junction solar cell, which injects electrons across the heterointerface to produce highly efficient impact ionization of carriers in the lowband-gap side of the junction, thereby conserving their total energy. Also, the superlattice structure has the advantage of relaxing the need for perfect lattice matching at the p-n interface and will inhibit the cross diffusion of dopant atoms that typically occurs in heavy doping. This structure avoids the use of tunnel junctions that make it very difficult to achieve the predicted efficiencies in cascade cells, thus making it possible to obtain energy efficiencies that are competitive with those predicted for cascade solar cells with reduced complexity and cost. This cell structure could also be incorporated into other solar cell structures designed for wider spectral coverage.

    This report describes work to reach two goals--an individual goal and a wide-gap team goal. The individual goal was to investigate the ``top junction`` for defects using the spectroscopic ellipsometry technique. This will include an evaluation if specific defects are associated with C, B, Sn (diffusing from the transparent conducting oxide [TCO]) or Na (diffusing from the glass). It may include an assessment of the function of a graded a-SiC:H buffer layer. As defects are identified and characterized, their influence on the transport properties will be assessed. This should lead to better parameters used as input to models for the electronic materials and device performance. The goal of the wide-gap team was to demonstrate, characterize, and understand improved doped and undoped ``wide gap`` materials for use in achieving 15%-efficient stabilized photovoltaic modules (``wide gap`` materials are defined by this team to have a band gap {ge} 1.9 eV). The major conclusions of the research are discussed in the report.

    The polycrystalline nature of thin-film CdTe and CuInSe{sub 2} solar cells continues to be a major factor in several individual losses that limit overall cell efficiency. This report describes progress in the quantitative separation of these losses, including both measurement and analysis procedures. It also applies these techniques to several individual cells to help document the overall progress with CdTe and CuInSe{sub 2} cells. Notably, CdTe cells from Photon Energy have reduced window photocurrent losses to 1 mA/Cm{sup 2}; those from the University of South Florida have achieved a maximum power voltage of 693 mV; and CuInSe{sub 2} cells from International Solar Electric Technology have shown a hole density as high as 7 {times} 10{sup 16} cm{sup {minus}3}, implying a significant reduction in compensation. 9 refs.

    Aim of this project is development and demonstration of processing steps necessary for fabrication of high efficiency CuInSe{sub 2} solar cells and sub-modules by the two-stage technique (also called the selenization method.) During this period, we have optimized the processing parameters of this method and demonstrated CuInSe{sub 2}/CdS/ZnO devices with a 1{endash}4 cm{sup 2} area and up to 12.4% active area efficiency. We have also developed a novel approach for the preparation of Cu/In precursors that improved the stoichiometric and morphological uniformity in these films. We have developed processing steps and tooling for handling up to 1 ft{sup 2} size substrates and as a result of these efforts demonstrated our first monolithically integrated sub-module of 1 ft{sup 2} area. 16 figs, 1 tab, 15 refs.

    This report describes progress during the first year of a 3-year program at Colorado School of Mines, based upon earlier studies performed by Ametek Corporation, to develop specific layers of the Ametek n-i-p structure as well as additional studies of several transparent conducting oxides. Thin films of ZnO and ZnO:Al were deposited under various conditions. For the n-layer of the Ametek structure, a dip-coating method was developed for the deposition of CdS films. The authors also present data on the characterization of these films by X-ray diffraction, Raman spectroscopy, scanning tunneling microscopy, small-angle X-ray scattering, and other techniques. They made progress in the electrodeposition of the CdTe i-layer of the Ametek structure. They developed appropriate electrochemical baths and are beginning to understand the role of the many experimental parameters that must be controlled to obtain high-quality films of this material. They explored the possibility of using an electrochemical process for fabricating the ZnTe p-layer. Some preliminary success was achieved, and this step will be pursued in the next phase. Finally, they fabricated a number of ``dot`` solar cells with the structure glass/SnO{sub 2}/CdS/CdTe/Au. Several cells with efficiencies in the range of 5%-6% were obtained, and they are confident, given recent progress, that cells with efficiencies in excess of 10% will be achieved in the near future.

    This report describes work to develop inverted-grown Al{sub 0.34}Ga{sub 0.66}As/GaAs cascades. Several significant developments are reported on as follows: (1) The AM1.5 1-sun total-area efficiency of the top Al{sub 0.34}Ga{sub 0.66}As cell for the cascade was improved from 11.3% to 13.2% (NREL measurement [total-area]). (2) The ``cycled`` organometallic vapor phase epitaxy growth (OMVPE) was studied in detail utilizing a combination of characterization techniques including Hall-data, photoluminescence, and secondary ion mass spectroscopy. (3) A technique called eutectic-metal-bonding (EMB) was developed by strain-free mounting of thin GaAs-AlGaAs films (based on lattice-matched growth on Ge substrates and selective plasma etching of Ge substrates) onto Si carrier substrates. Minority-carrier lifetime in an EMB GaAs double-heterostructure was measured as high as 103 nsec, the highest lifetime report for a freestanding GaAs thin film. (4) A thin-film, inverted-grown GaAs cell with a 1-sun AM1.5 active-area efficiency of 20.3% was obtained. This cell was eutectic-metal-bonded onto Si. (5) A thin-film inverted-grown, Al{sub 0.34}Ga{sub 0.66}As/GaAs cascade with AM1.5 efficiency of 19.9% and 21% at 1-sun and 7-suns, respectively, was obtained. This represents an important milestone in the development of an AlGaAs/GaAs cascade by OMVPE utilizing a tunnel interconnect and demonstrates a proof-of-concept for the inverted-growth approach.

    This project is a coordinated effort to develop process technology for the degradation of lignocellulosic biomass and its utilization for the production of liquid fuels. Current efforts are based on our prior success in developing a single-step microbiological process for the conversion of lignocellulose to ethanol. This process utilizes a mixed culture of Clostridium thermocellum, a thermophilic cellulolytic anaerobe which degrades cellulose and hemicellulose to fermentable sugars, and Clostridium thermosaccharolyticum, a thermo anaerobe which produces high concentrations of ethanol from both hexoses and pentoses. The proposed studies will focus on the use of C. thermocellum and its cellulases for enhanced saccharification of lignocellulose and on the direct fermentation of lignocellulose to the liquid fuel, butanol. Efforts on saccharification are directed to facilitate the adoption of existing fermentation ethanol plants for cellulosic substrates and to overcome the rate limiting step of saccharification in the mixed culture. The effort on butanol will extend the concept of direct fermentation to the production of this liquid fuel. 14 refs.
