International Energy Outlook 2000 - Hydroelectricity and Other Renewable  

Gasoline and Diesel Fuel Update (EIA)

The renewable energy share of total world energy consumption is expected to continue at a level of about 8 percent from 1997 through 2020, despite a projected 54-percent increase in consumption of hydroelectricity and other renewable resources. The renewable energy share of total world energy consumption is expected to continue at a level of about 8 percent from 1997 through 2020, despite a projected 54-percent increase in consumption of hydroelectricity and other renewable resources. The development of renewable energy sources is constrained in the International Energy Outlook 2000 (IEO2000) reference case projections by expectations that fossil fuel prices will remain low and, as a result, renewables will have a difficult time competing. Although energy prices rebounded in 1999 from 1998 lows, it remains unlikely that renewable energy can compete economically over the projection period. Failing a strong worldwide commitment to environmental considerations, such as the limitations and reductions of carbon emissions outlined in the Kyoto

International Energy Outlook 1999 - Hydroelectricity and Other Renewable  

Gasoline and Diesel Fuel Update (EIA)

hydroelectricty.gif (7905 bytes) hydroelectricty.gif (7905 bytes) Renewable energy use is projected to increase by 62 percent between 1996 and 2020. Almost half the increase is expected in the developing world, where large-scale hydroelectric projects still are being undertaken. Low prices for oil and natural gas in world energy markets continued to diminish the potential for rapid development of renewable energy sources worldwide. Oil prices hit 20-year lows in 1998, in part because the Asian economic crisis resulted in lower worldwide demand. Even production cut agreements by some major oil producers, such as Saudi Arabia, Mexico, and Venezuela, failed to provide measurable price recovery during 1998. On the positive side, the Kyoto Climate Change Protocol proposals to cut greenhouse gas emissions levels may provide an opportunity for growth in

Photovoltaics can literally be translated as light-electricity. First used in about 1890, "photovoltaic" has two parts: photo, derived from the Greek word for light, and volt, relating to electricity pioneer Alessandro Volta. And this is what photovoltaic materials and devices do-they convert light energy into electrical energy, as French physicist Edmond Becquerel discovered as early as 1839. Becquerel discovered the process of using sunlight to produce an electric current in a solid material. But it took more than another century to truly

Concentrator Photovoltaic System Basics Concentrator Photovoltaic System Basics Concentrator Photovoltaic System Basics August 20, 2013 - 4:12pm Addthis Concentrator photovoltaic (PV) systems use less solar cell material than other PV systems. PV cells are the most expensive components of a PV system, on a per-area basis. A concentrator makes use of relatively inexpensive materials such as plastic lenses and metal housings to capture the solar energy shining on a fairly large area and focus that energy onto a smaller area-the solar cell. One measure of the effectiveness of this approach is the concentration ratio-in other words, how much concentration the cell is receiving. Concentrator PV systems have several advantages over flat-plate systems. First, concentrator systems reduce the size or number of cells needed and

Hybrid photovoltaic/thermal solar energy system  

DOE Green Energy (OSTI)

Heating and cooling systems that use hybrid solar energy collectors (combination photovoltaic-thermal) have the potential for considerable energy savings, particularly when the system includes a heat pump. Economic evaluations show that photovoltaic systems are potentially most economical, but results depend critically on future collector costs as well as energy prices. Results are based on a specially developed computer program that predicted the total auxiliary energy required for five different solar heating/cooling systems. Performance calculations for a modeled residence and small office building were made using meteorological data from four geographic locations. Annual system costs were also calculated.

Energy supply is one of the most important issues facing Northwestern legislators today. To meet the challenge, state legislatures must address the development of alternative energy sources. The Small-Scale Hydroelectric Power Policy Project of the National Conference of State Legislators (NCSL) was designed to assist state legislators in looking at the benefits of one alternative, small-scale hydro. Because of the need for state legislative support in the development of small-scale hydroelectric, NCSL, as part of its contract with the Department of Energy, conducted the following conference on small-scale hydro in the Pacific Northwest. The conference was designed to identify state obstacles to development and to explore options for change available to policymakers. A summary of the conference proceedings is presented.

Images of energy: Policy perspectives on the introduction of hydroelectricity in Italy, 1882-1914  

Science Conference Proceedings (OSTI)

This study considers the link between energy technologies and cultural attitudes. Contemporary energy policy makers lack the conceptual tools with which to evaluate culturally appropriate energy choices. A way to regain a contextual capability is needed; that is, the capacity to recognize and avert situations where technological advance is insufficiently harmonized with its embedding environment. This study explores how both policy makers and the general public form their [open quotes]images of energy.[close quotes] It does so in three parts, beginning with an examination of the concepts of [open quotes]technology,[close quotes] [open quotes]culture[close quotes] and [open quotes]cognitive map,[close quotes] and an explanation of their interrelationship. The second part presents two historical case-studies of the introduction of hydroelectricity in Italy from 1882-1914. It considers how a relatively unknown technology made its way into urban and rural life, who its primary surveyors were, and how it shaped and was shaped by the cognitive maps of those into whose lives it marched. The final part extends the investigation to contemporary socio-cultural dynamics. Through concepts derived from General System Theory, the process of technological integration is interpreted in light of events that shape the world today. The design of a model to be used by energy makers and educators alike in conceiving culturally attuned energy alternatives is proposed. Such a model would describe energy-related cognitive maps and could serve as the basis for informed decision-making on energy choice at all levels of society. The study concludes with suggestions for a research agenda to further explore individual and collective energy-related cognitive maps.

System Basics System Basics Photovoltaic System Basics August 20, 2013 - 4:00pm Addthis A photovoltaic (PV), or solar electric system, is made up of several photovoltaic solar cells. An individual PV cell is usually small, typically producing about 1 or 2 watts of power. To boost the power output of PV cells, they are connected together to form larger units called modules. Modules, in turn, can be connected to form even larger units called arrays, which can be interconnected to produce more power, and so on. In this way, PV systems can be built to meet almost any electric power need, small or large. Illustration of solar cells combined to make a module and modules combined to make an array.

Interim performance criteria for photovoltaic energy systems. [Glossary included  

DOE Green Energy (OSTI)

This document is a response to the Photovoltaic Research, Development, and Demonstration Act of 1978 (P.L. 95-590) which required the generation of performance criteria for photovoltaic energy systems. Since the document is evolutionary and will be updated, the term interim is used. More than 50 experts in the photovoltaic field have contributed in the writing and review of the 179 performance criteria listed in this document. The performance criteria address characteristics of present-day photovoltaic systems that are of interest to manufacturers, government agencies, purchasers, and all others interested in various aspects of photovoltaic system performance and safety. The performance criteria apply to the system as a whole and to its possible subsystems: array, power conditioning, monitor and control, storage, cabling, and power distribution. They are further categorized according to the following performance attributes: electrical, thermal, mechanical/structural, safety, durability/reliability, installation/operation/maintenance, and building/site. Each criterion contains a statement of expected performance (nonprescriptive), a method of evaluation, and a commentary with further information or justification. Over 50 references for background information are also given. A glossary with definitions relevant to photovoltaic systems and a section on test methods are presented in the appendices. Twenty test methods are included to measure performance characteristics of the subsystem elements. These test methods and other parts of the document will be expanded or revised as future experience and needs dictate.

The four basic device designs are: Homojunction Devices Crystalline silicon is the primary example of this kind of cell. A single material-crystalline silicon-is altered so that one side is p-type, dominated by positive holes, and the other side is n-type, dominated by negative electrons. The p/n junction is located so that the maximum light is absorbed near it. The free electrons and holes generated by light deep in the silicon diffuse to the p/n junction and then separate to produce a current if the silicon is of sufficiently high quality. In this homojunction design, these aspects of the cell may be varied to

Energy.gov (U.S. Department of Energy (DOE)) Indexed Site

System Performance Basics System Performance Basics Photovoltaic System Performance Basics August 20, 2013 - 4:17pm Addthis Photovoltaic (PV) systems are usually composed of numerous solar arrays, which in turn, are composed of numerous PV cells. The performance of the system is therefore dependent on the performance of its components. Reliability The reliability of PV arrays is an important factor in the cost of PV systems and in consumer acceptance. However, the building blocks of arrays, PV cells, are considered "solid-state" devices with no moving parts and, therefore, are highly reliable and long-lived. Therefore, reliability measurements of PV systems are usually focused not on cells but on modules and whole systems. Reliability can be improved through fault-tolerant circuit design, which

Cell Basics Cell Basics Photovoltaic Cell Basics August 16, 2013 - 4:53pm Addthis Photovoltaic (PV) cells, or solar cells, take advantage of the photoelectric effect to produce electricity. PV cells are the building blocks of all PV systems because they are the devices that convert sunlight to electricity. Commonly known as solar cells, individual PV cells are electricity-producing devices made of semiconductor materials. PV cells come in many sizes and shapes, from smaller than a postage stamp to several inches across. They are often connected together to form PV modules that may be up to several feet long and a few feet wide. Modules, in turn, can be combined and connected to form PV arrays of different sizes and power output. The modules of the array make up the major part of a PV system, which can also include electrical connections,

Silicon Cell Basics Silicon Cell Basics Photovoltaic Silicon Cell Basics August 20, 2013 - 2:19pm Addthis Silicon-used to make some the earliest photovoltaic (PV) devices-is still the most popular material for solar cells. Silicon is also the second-most abundant element in the Earth's crust (after oxygen). However, to be useful as a semiconductor material in solar cells, silicon must be refined to a purity of 99.9999%. In single-crystal silicon, the molecular structure-which is the arrangement of atoms in the material-is uniform because the entire structure is grown from the same crystal. This uniformity is ideal for transferring electrons efficiently through the material. To make an effective PV cell, however, silicon has to be "doped" with other elements to make n-type and p-type layers.

Photovoltaics as an operating energy system  

DOE Green Energy (OSTI)

In the short time since the discovery of the modern solar cell in 1954, terrestrial photovoltaic power system technology has matured in all areas, from collector reliability to system and subsystem design and operations. Today's PV systems are finding widespread use in powering loads where conventional sources are either unavailable, unreliable, or too costly. A broad range of applications is possible because of the modularity of the technology---it can be used to power loads ranging from less than a watt to several megawatts. This inherent modularity makes PV an excellent choice to play a major role in rural electrification in the developing world. The future for grid-connected photovoltaic systems is also very promising. Indications are that several of today's technologies, at higher production rates and in megawatt-sized installations, will generate electricity in the vicinity of $0.12/kWh in the near future. 12 refs., 3 figs.

Department of Energy: Photovoltaics program - FY 1996  

DOE Green Energy (OSTI)

The National Photovoltaic Program supports efforts to make PV an important part of the US economy through three main program elements: Research and Development, Technology Development, and Systems Engineering and Applications. (1) Research and Development activities generate new ideas, test the latest scientific theories, and push the limits of PV efficiencies in laboratory and prototype materials and devices. (2) Technology Development activities apply laboratory innovations to products to improve PV technology and the manufacturing techniques used to produce PV systems for the market. (3) Systems Engineering and Applications activities help improve PV systems and validate these improvements through tests, measurements, and deployment of prototypes. In addition, applications research validates, sales, maintenance, and financing mechanisms worldwide. (4) Environmental, Health, Safety and Resource Characterization activities help to define environmental, health and safety issues for those facilities engaged in the manufacture of PV products and organizations engaged in PV research and development. All PV Program activities are planned and executed in close collaboration and partnership with the U.S. PV industry. The overall PV Program is planned to be a balanced effort of research, manufacturing development, and market development. Critical to the success of this strategy is the National Photovoltaic Program`s effort to reduce the cost of electricity generated by photovoltaic. The program is doing this in three primary ways: by making devices more efficient, by making PV systems less expensive, and by validating the technology through measurements, tests, and prototypes.

Standards for photovoltaic energy conversion systems. Final report  

DOE Green Energy (OSTI)

This report provides the results of a search for existing domestic standards and related documents for possible application in the development of a standards base for photovoltaic energy conversion systems. The search resulted in locating about 150 test methods, recommended practices, standards, solar-thermal performance criteria, and other standards-related documents. They are listed by topic areas in the appendix. The listing was prepared to assist those involved in developing performance criteria for photovoltaic systems and in identifying methods to test system performance against these criteria. It is clear from the results of the search that few standards are directly applicable to terrestrial solar photovoltaic systems and that much standards development is required to support the commercialization of such systems.

Energy.gov (U.S. Department of Energy (DOE)) Indexed Site

Cell Quantum Efficiency Basics Cell Quantum Efficiency Basics Photovoltaic Cell Quantum Efficiency Basics August 20, 2013 - 3:05pm Addthis Quantum efficiency (QE) is the ratio of the number of charge carriers collected by a photovoltaic (PV) cell to the number of photons-or packets of light-of a given energy shining on the solar cell. Quantum efficiency therefore relates to the response of a solar cell to the various wavelengths in the spectrum of light shining on the cell. The QE is given as a function of either wavelength or energy. If all the photons of a certain wavelength are absorbed and the resulting minority carriers (for example, electrons in a p-type material) are collected, then the QE at that particular wavelength has a value of one. The QE for photons with energy below the bandgap is zero.

Photovoltaic energy impacts on US CO{sub 2} emissions  

DOE Green Energy (OSTI)

The potential role of photovoltaic (PV) technology in reducing CO{sub 2} emissions was evaluated in an energy-environmental economic systems model. The model examines the role of photovoltaic energy systems in a competitive market environment. PV technology is already competitive for certain niche markets. Further growth in those markets is expected as well as expansion into other markets. Decreasing cost penalties should provide greater incentive for expansion of niche markets. This analysis indicated that, while PV was not projected to be competitive as a general source of electricity supply to the grid by 2030, it did become an attractive technology for this purpose after 2010 under carbon constraint, even if the carbon constraint was limited to stability of emissions at the 1990 level.

Analysis of Photovoltaic System Energy Performance Evaluation Method  

SciTech Connect

Documentation of the energy yield of a large photovoltaic (PV) system over a substantial period can be useful to measure a performance guarantee, as an assessment of the health of the system, for verification of a performance model to then be applied to a new system, or for a variety of other purposes. Although the measurement of this performance metric might appear to be straight forward, there are a number of subtleties associated with variations in weather and imperfect data collection that complicate the determination and data analysis. A performance assessment is most valuable when it is completed with a very low uncertainty and when the subtleties are systematically addressed, yet currently no standard exists to guide this process. This report summarizes a draft methodology for an Energy Performance Evaluation Method, the philosophy behind the draft method, and the lessons that were learned by implementing the method.

Fish and hydroelectricity; Engineering a better coexistence  

Science Conference Proceedings (OSTI)

This paper reports on the problems that hydroelectric plants have regarding fish populations. The utilities that operate these plants are finding that accommodating migrating fish presents unique engineering challenges, not the least of which involves designing and building systems to protect fish species whose migratory behavior remains something of a mystery. Where such systems cannot be built, the status of hydroelectric dams may be in doubt, as is now the case with several dams in the United States. A further twist in some regions in the possibility that certain migratory fish will be declared threatened or endangered-a development that could wreak havoc on the hydroelectric energy supply in those regions.

Survey and screening of intermediate-size photovoltaic total energy and electric applications  

DOE Green Energy (OSTI)

One of the principal objectives of this photovoltaic mission analysis effort has been to identify and evaluate applications for photovoltaic solar energy conversion that could lead to significant contributions to the national energy supply and that would provide attractive opportunities for application experiments aimed at stimulating the adoption of photovoltaic technology. The scope of the study has included applications both for electric-only photovoltaic (PV) systems and for photovoltaic total energy systems (PTES), i.e., systems that provide both photovoltaic electricity and solar thermal energy to meet all or part of the energy demand at a single load point or a group of related load points. In either case, both flat-plate and concentrating systems have been considered and it has been assumed that the thermal energy is collected in and transported by the fluid used in an active cooling system for the photovoltaic cells. Because the efficiency of photovoltaic devices decreases rapidly with increasing temperature and because the operational lifetime of such devices is reduced by prolonged operation at elevated temperatures, a practical upper limit of about 200/sup 0/C (400/sup 0/F) was assumed for the temperature at which arrays can be allowed to be operated. This limitation, in turn, places an upper bound on the temperature at which solar thermal energy is available in PTES applications. An initial screening aimed at identifying the most promising applications has therefore been required, with the expectation that detailed evaluation will be made of only the higher-ranking candidates. A description of the screening procedure that was adopted and a discussion of the results are presented.

Mission analysis of photovoltaic solar energy systems. Final report. Volume I. Summary  

SciTech Connect

A summary report of a study program whose principal objective was to develop methods for the technical and economic evaluation of potential missions (applications) for photovoltaic solar energy conversion in the southwestern United States in the 1980 to 2000 period is presented. A secondary objective was to apply the methodology, when developed, to the evaluation of a number of illustrative examples of candidate missions in order to obtain at least a preliminary indication of the competitive position of the photovoltaic technology in the future energy economy of the Southwest. Because of their large potential significance, most of the effort in the study was devoted to two main classes of missions: on-site applications (in which the photovoltaic system serves an electric load point that is colocated with the system) and central station power plant applications. A smaller amount of attention was given to the electrolytic production of hydrogen with electric power generated by the photovoltaic conversion of solar energy. (WHK)

Analysis of photovoltaic total energy systems for single family residential applications  

DOE Green Energy (OSTI)

The performance and cost-effectiveness of three photovoltaic total energy system concepts designed to meet the thermal and electrical demands of a typical single family house are compared. The three photovoltaic total energy system concepts considered are: (1) All-photovoltaic systems. Passively air-cooled photovoltaic panels provide electricity to meet both electrical and thermal demands. (2) Separate-panel systems. Solar thermal panels provide thermal energy, while passively air-cooled photovoltaic panels serve the purely electric demand. (3) Combined thermal/electric panel systems. Water-cooled photovoltaic panels provide both thermal energy (transported by cooling water) and electrical energy to meet the separate thermal and electrical demands. Additional passively air-cooled photovoltaic panels are added, as required, to meet the electrical demand. The thermal demand is assumed to consist of the energy required for domestic hot water and space heating, while the electrical demand includes the energy required for baseload power (lights, appliances, etc.) plus air conditioning. An analysis procedure has been developed that permits definition of the panel area, electrical and/or thermal storage capacity, and utility backup energy level that, in combination, provide the lowest annual energy cost to the homeowner for each system concept for specified assumptions about costs and system operations. The procedure appears capable of being used to approximately any size system using solar collectors, as well as in any application where the thermal and/or electrical demand is being provided by solar energy, with utility or other conventional backup. This procedure has been used to provide results for homes located in Phoenix, Arizona, and Madison, Wisconsin, and to evaluate the effects of array and backup power costs and the desirability of selling excess electrical energy back to the utility.

EVALUATION OF FLAT-PLATE PHOTOVOLTAIC THERMAL HYBRID SYSTEMS FOR SOLAR ENERGY UTILIZATION.  

DOE Green Energy (OSTI)

The technical and economic attractiveness of combined photovoltaic/thermal (PV/T) solar energy collectors was evaluated. The study was limited to flat-plate collectors since concentrating photovoltaic collectors require active cooling and thus are inherently PV/T collectors, the only decision being whether to use the thermal energy or to dump it. it was also specified at the outset that reduction in required roof area was not to be used as an argument for combining the collection of thermal and electrical energy into one module. Three tests of economic viability were identified, all of which PV/T must pass if it is to be considered a promising alternative: PV/T must prove to be competitive with photovoltaic-only, thermal-only, and side-by-side photovoltaic-plus-thermal collectors and systems. These three tests were applied to systems using low-temperature (unglazed) collectors and to systems using medium-temperature (glazed) collectors in Los Angeles, New York, and Tampa. For photovoltaics, the 1986 DOE cost goals were assumed to have been realized, and for thermal energy collection two technologies were considered: a current technology based on metal and glass, and a future technology based on thin-film plastics. The study showed that for medium-temperature applications PV/T is not an attractive option in any of the locations studied. For low-temperature applications, PV/T appears to be marginally attractive.

Lithium Ion Cell Development for Photovoltaic Energy Storage Applications  

Science Conference Proceedings (OSTI)

The overall project goal is to reduce the cost of home and neighborhood photovoltaic storage systems by reducing the single largest cost component ?? the energy storage cells. Solar power is accepted as an environmentally advantaged renewable power source. Its deployment in small communities and integrated into the grid, requires a safe, reliable and low cost energy storage system. The incumbent technology of lead acid cells is large, toxic to produce and dispose of, and offer limited life even with significant maintenance. The ideal PV storage battery would have the safety and low cost of lead acid but the performance of lithium ion chemistry. Present lithium ion batteries have the desired performance but cost and safety remain the two key implementation barriers. The purpose of this project is to develop new lithium ion cells that can meet PVES cost and safety requirements using A123Systems phosphate-based cathode chemistries in commercial PHEV cell formats. The cost target is a cell design for a home or neighborhood scale at <$25/kWh. This DOE program is the continuation and expansion of an initial MPSC (Michigan Public Service Commission) program towards this goal. This program further pushes the initial limits of some aspects of the original program ?? even lower cost anode and cathode actives implemented at even higher electrode loadings, and as well explores new avenues of cost reduction via new materials ?? specifically our higher voltage cathode. The challenge in our materials development is to achieve parity in the performance metrics of cycle life and high temperature storage, and to produce quality materials at the production scale. Our new cathode material, M1X, has a higher voltage and so requires electrolyte reformulation to meet the high temperature storage requirements. The challenge of thick electrode systems is to maintain adequate adhesion and cycle life. The composite separator has been proven in systems having standard loading electrodes; the challenge with this material will be to maintain proven performance when this composite is coated onto a thicker electrode; as well the high temperature storage must meet application requirements. One continuing program challenge was the lack of specific performance variables for this PV application and so the low power requirements of PHEV/EV transportation markets were again used.

Underground pumped hydroelectric storage  

DOE Green Energy (OSTI)

Underground pumped hydroelectric energy storage was conceived as a modification of surface pumped storage to eliminate dependence upon fortuitous topography, provide higher hydraulic heads, and reduce environmental concerns. A UPHS plant offers substantial savings in investment cost over coal-fired cycling plants and savings in system production costs over gas turbines. Potential location near load centers lowers transmission costs and line losses. Environmental impact is less than that for a coal-fired cycling plant. The inherent benefits include those of all pumped storage (i.e., rapid load response, emergency capacity, improvement in efficiency as pumps improve, and capacity for voltage regulation). A UPHS plant would be powered by either a coal-fired or nuclear baseload plant. The economic capacity of a UPHS plant would be in the range of 1000 to 3000 MW. This storage level is compatible with the load-leveling requirements of a greater metropolitan area with population of 1 million or more. The technical feasibility of UPHS depends upon excavation of a subterranean powerhouse cavern and reservoir caverns within a competent, impervious rock formation, and upon selection of reliable and efficient turbomachinery - pump-turbines and motor-generators - all remotely operable.

Front Surface Materials The front surface of a flat-plate PV module must have a high transmission in the wavelengths that can be used by the solar cells in the module. For example, for silicon solar cells, the top surface must have high transmission of light with wavelengths from 350 to 1200 nm. Also, reflection from the front surface should be minimal. An antireflection coating added to the top surface can greatly reduce the reflection of sunlight, and texturing of the surface can cause light that strikes the surface to stay within the cells.

Energy analysis of facade-integrated photovoltaic systems applied to UAE commercial buildings  

SciTech Connect

Developments in the design and manufacture of photovoltaic cells have recently been a growing concern in the UAE. At present, the embodied energy pay-back time (EPBT) is the criterion used for comparing the viability of such technology against other forms. However, the impact of PV technology on the thermal performance of buildings is not considered at the time of EPBT estimation. If additional energy savings gained over the PV system life are also included, the total EPBT could be shorter. This paper explores the variation of the total energy of building integrated photovoltaic systems (BiPV) as a wall cladding system applied to the UAE commercial sector and shows that the ratio between PV output and saving in energy due to PV panels is within the range of 1:3-1:4. The result indicates that for the southern and western facades in the UAE, the embodied energy pay-back time for photovoltaic system is within the range of 12-13 years. When reductions in operational energy are considered, the pay-back time is reduced to 3.0-3.2 years. This study comes to the conclusion that the reduction in operational energy due to PV panels represents an important factor in the estimation of EPBT. (author)

Mission analysis of photovoltaic solar energy conversion. Volume I. Executive summary  

DOE Green Energy (OSTI)

An investigation of terrestrial applications for the photovoltaic conversion of solar energy is summarized. The specific objectives of the study were: (a) to survey and evaluate near-term (1976--1985) civilian photovoltaic applications in the United States; (b) to evaluate the most promising major missions for the mid-term period (1986--2000) and to determine the conditions under which photovoltaic technology can compete in those applications at array prices consistent with ERDA goals; (c) to address critical external issues and identify the sensitivity of photovoltaic system technical requirements to such factors; and (d) to quantify the societal costs of alternative energy sources and identify equalizing incentives. The study was divided into six separate but interrelated tasks: Task 1, Analysis of Near-Term Applications; Task 2, Analysis of Major Mid-Term Missions; Task 3, Review and Updating of the ERDA Technology Implementation Plan; Task 4, Critical External Issues; Task 5, The Impact of Incentives; and Task 6, The Societal Costs of Conventional Power Generation. The emphasis of the study was on the first two of these tasks, the other four serving to provide supplementary information.

Tariffs Can Be Structured to Encourage Photovoltaic Energy

The solar power market is growing at a quickening pace, fueled by an array of national and local initiatives and policies aimed at improving the value proposition of customer-sited photovoltaic (PV) systems. Though these policies take many forms, they commonly include up-front capital cost rebates or ongoing production incentives, supplemented by net metering requirements to ensure that customer-sited PV systems offset the full retail rate of the customer-hosts. Somewhat less recognized is the role of retail rate design, beyond net metering, on the customer-economics of grid-connected PV. Over the life of a PV system, utility bill savings represent a substantial portion of the overall economic value received by the customer. At the same time, the design of retail electricity rates, particularly for commercial and industrial customers, can vary quite substantially. Understanding how specific differences in rate design affect the value of customer-sited PV is therefore essential to supporting the continued growth of this market.

Maximally concentrating optics for photovoltaic solar energy conversion  

DOE Green Energy (OSTI)

Use of a two-stage concentrator with a fresnel lens primary and a nonimaging dielectric totally internally reflecting secondary, has unique advantages for photovoltaic concentration. Some preliminary ray trace studies have shown that with planar lenses, an increase in angular acceptance for a given geometric concentration to about 2/3 of the maximum theoretical limit can be achieved. To demonstrate this, two preprototype concentrators, each having a geometric concentration of 248:1 for a 0.635cm (0.25 inch) diameter cell, have been designed, built, and tested. Measurements of the angular response show an acceptance of 8[degrees] (full angle) which is drastically better than the 1[degrees]--2[degrees] achievable without a secondary, and is in excellent agreement with the ray trace predictions. For these preprototypes, passive cooling was sufficient to prevent any thermal problems for both the cell and secondary. No problems associated with nouuniform cell illumination were found, as evidenced by the fill factor of 71%--73% measured under concentration. Initial measurements of the system electrical efficiency lie in the range 7.5%--9.9% for a variety of individual cells.

Maximally concentrating optics for photovoltaic solar energy conversion  

DOE Green Energy (OSTI)

The use of a two-stage concentrator with a fresnel lens primary and a non-imaging dielectric totally internally reflecting secondary, has unique advantages for photovoltaic concentration. This new design has a much larger acceptance angle than the conventional lens-cell concentrating system. In the continuation of this research, an optimally designed prototype which employs a 13.6-cm diameter flat fresnel tons as the primary focusing device, a dielectric compound hyperbolic concentrator (DCHC) as secondary and a 1-cm diameter high-concentration cell for electricity conversion has been built, tested and analyzed. Measurements under sunlight show that it has an angular acceptance of [plus minus]3.6 degrees, which is dramatically better than the [plus minus]0.5 degree achievable without a secondary concentrator. This performance agrees well with theoretical ray-tracing predictions. The secondary shows an optical efficiency of (91[plus minus]2)% at normal incidence. Combining with the primary fresnel tens which has an optical efficiency of (82[plus minus]2)%, tho two-stage system yields a total optical efficiency of (7l[plus minus]2)%. The measurement of the system electrical performance yielded a net electrical efficiency of 11.9%. No problems associated with non-uniform cell illumination were found, as evidenced by the excellent fill factor of (79[plus minus]2)% measured under concentration. The secondary geometrical properties and the optimal two-stage design procedures for various primary- cell combinations were systematical studied. A general design principle has been developed.

Graphene-based photovoltaic cells for near-field thermal energy conversion  

E-Print Network (OSTI)

Thermophotovoltaic devices are energy-conversion systems generating an electric current from the thermal photons radiated by a hot body. In far field, the efficiency of these systems is limited by the thermodynamic Schockley-Queisser limit corresponding to the case where the source is a black body. On the other hand, in near field, the heat flux which can be transferred to a photovoltaic cell can be several orders of magnitude larger because of the contribution of evanescent photons. This is particularly true when the source supports surface polaritons. Unfortunately, in the infrared where these systems operate, the mismatch between the surface-mode frequency and the semiconductor gap reduces drastically the potential of this technology. Here we show that graphene-based hybrid photovoltaic cells can significantly enhance the generated power paving the way to a promising technology for an intensive production of electricity from waste heat.

Photovoltaics as a worldwide energy option: A case study in development strategy  

SciTech Connect

Renewable energy technologies, such as solar thermal electric, photovoltaics (PV), and wind energy have made significant gains in cost and performance in the past decades. As a result, there have been high expectations on the part of the public for these sources to play a major role in future energy supply, especially as environmental concerns about conventional sources increase. Despite these past gains and high expectations, the global potential of renewable energy technologies still remains largely untapped, principally because of issues of industrialization and user acceptance. There is increasing recognition that government energy programs must incorporate a broader strategy than the traditional basic research role if they are to address these issues. Essential elements of this strategy are affordable technology, a healthy industry, sustained market growth, user acceptance, and equitable policy and financial environments. The US Department of Energy (DOE) programs in solar electric conversion have already started the development of the required broader-based effort. This paper presents the status of that work, utilizing the US National Photovoltaic Program as a case study.

Health, safety and environmental issues relating to cadmium usage in photovoltaic energy systems  

DOE Green Energy (OSTI)

This paper discusses the current technology base and hazards associated with two promising thin-film photovoltaic cells that contain cadmium compounds -- cadmium telluride (CdTe) and copper indium diselenide (CuInSe{sub 2}). More specifically, this paper summarizes the toxicological information on cadmium (Cd) compounds; evaluates potential health, safety and environmental hazards associated with cadmium usage in the photovoltaics industry; describes regulatory requirements associated with the use, handling and disposal of cadmium compounds; and lists management options to permit the safe and continued use of these materials. Handling of cadmium in photovoltaic production can present hazards to health, safety and the environment. Prior recognition of these hazards can allow device manufacturers and regulators to implement appropriate and readily available hazard management strategies. Hazards associated with product use (i.e., array fires) and disposal remain controversial and partially unresolved. The most likely effects that could be expected would be those associated with chronic low-level exposures to cadmium wastes. Because of the general immobility of the cadmium present in these devices and availability of environmental and biomonitoring protocols, chronic hazards can be monitored, and remediated if necessary. Nevertheless, concern about cadmium hazards should continue to be emphasized to ensure that health, safety and environmental issues are properly managed. At the same time, the potential role that these systems can play in ameliorating some important health and environmental hazards related to other energy systems should not be ignored. 27 refs., 5 figs., 2 tabs.

A comparison of photovoltaic module performance evaluation methodologies for energy ratings  

DOE Green Energy (OSTI)

The rating of photovoltaic (PV) modules has always been a controversial topic in the PV community. Currently, there is no industry standard methodology to evaluate PV modules for energy production. This issue must be discussed and resolved for the benefit of system planners, utilities, and other consumers. Several methodologies are available to rate a module`s peak power, but do any accurately predict energy output for flat-plate modules? This paper analyzes the energy performance of PV modules using six different energy calculation techniques and compares the results to the measured amount of energy produced. The results indicate which methods are the most effective for predicting energy output in Golden, Colorado, under prevailing meteorological conditions.

Environmental requirements at hydroelectric power plants  

DOE Green Energy (OSTI)

Hydroelectric power is the most mature and widely implemented of the renewable energy technologies. The energy of flowing water has been used to perform work directly since ancient times, and the use of hydropower turbines to generate electricity traces back to the 19th century. Two commonly used turbine types, the Francis and Kaplan turbines, are essentially refinements of the simple reaction turbine of Hero of Alexandria, dating from about 100 B.C. (NAS 1976). Hydroelectric power production provides over 10% of the net electrical generation in the US, more than petroleum or natural gas and far more than the other renewable energy technologies combined. On a regional basis, hydroelectric power represents 14% of the net electrical power generation in the Rocky Mountain states and nearly 63% along the Pacific Coast. Those states that have the largest percentages of their electricity generated by hydropower (e.g., Idaho, Oregon, Montana, and Washington) also tend to have the lowest average cost of electricity per kilowatt-hour.

Power Electronics Design Implications of Novel Photovoltaic Collector Geometries and Their Application for Increased Energy Harvest  

E-Print Network (OSTI)

The declining cost of photovoltaic (PV) modules has enabled the vision of ubiquitous photovoltaic (PV) power to become feasible. Emerging PV technologies are facilitating the creation of intentionally non-flat PV modules, which create new applications for this sustainable energy generation currently not possible with the traditional rigid, flat silicon-glass modules. However, since the photovoltaic cells are no longer coplanar, there are significant new requirements for the power electronics necessary to convert the native form of electricity into a usable form and ensure maximum energy harvest. Non-uniform insolation from cell-to-cell gives rise to non-uniform current density in the PV material, which limits the ability to create series-connected cells without bypass diode or other ways to shunt current, which is well known in the maximum power tracking literature. This thesis presents a modeling approach to determine and quantify the variations in generation of energy due to intentionally non-flat PV geometries. This will enable the power electronics circuitry to be optimized to harvest maximum energy from PV pixel elements clusters of PV cells with similar operating characteristics. This thesis systematically compares different geometries with identical two-dimensional projection "footprints" for energy harvest throughout the day. The results show that for the same footprint, a semi-cylindrical surface harvests more energy over a typical day than a flat plate. The modeling approach is then extended to demonstrate that by using non flat geometries for PV panel, the availability of a remotely located stand-alone power system can be increased when compared to a flat panel of same footprint. These results have broad application to a variety of energy scavenging scenarios in which either total energy harvested needs to be maximized or unusual geometries for the PV active surfaces are required, including building-integrated PV. This thesis develops the analysis of the potential energy harvest gain for advanced non-planar PV collectors as a necessary first step towards the design of the power electronics circuits and control algorithms to take advantage of the new opportunities of conformal and non-flat PV collectors.

Performance of a grid connected residential photovoltaic system with energy storage  

DOE Green Energy (OSTI)

In 1995, Salt River Project (SRP), a public power utility located in Phoenix, Arizona, collaborated with the Electric Power Research Institute (EPRI) and Sandia National Laboratories (Sandia) to initiate a photovoltaic (PV) power system with battery energy storage to match PV output with residential customer peak energy demand periods. The PV power system, a 2.4kW PV array with 25.2kWh of energy storage, was designed and installed by Southwest Technology Development Institute (SWTDI) at an SRP-owned facility, known as the Chandler Research House during August 1995. This paper presents an overview of the system design, operation and performance. 3 refs., 2 figs., 2 tabs.

Polaron Absorption for Photovoltaic Energy Conversion in a Manganite-titanate pn Heterojunction  

Science Conference Proceedings (OSTI)

The relation among structure, electric transport, and photovoltaic effect is investigated for a pn heterojunction with strong correlation interactions. A perovskite interface is chosen as a model system consisting of the p-doped strongly correlated manganite Pr{sub 0.64}Ca{sub 0.36}MnO{sub 3} (PCMO) and the n-doped titanate SrTi{sub 1-y}Nb{sub y}O{sub 3} (y = 0.002 and 0.01). High-resolution electron microscopy and spectroscopy reveal a nearly dislocation-free, epitaxial interface and give insight into the local atomic and electronic structure. The presence of a photovoltaic effect under visible light at room temperature suggests the existence of mobile excited polarons within the band-gap-free PCMO absorber. The temperature-dependent rectifying current-voltage characteristics prove to be mainly determined by the presence of an interfacial energy spike in the conduction band and are affected by the colossal electroresistance effect. From the comparison of photocurrents and spatiotemporal distributions of photogenerated carriers (deduced from optical absorption spectroscopy), we discuss the range of the excited polaron diffusion length.

Do Photovoltaic Energy Systems Effect Residential Selling Prices? Results from a California Statewide Investigation.  

DOE Green Energy (OSTI)

An increasing number of homes in the U.S. have sold with photovoltaic (PV) energy systems installed at the time of sale, yet relatively little research exists that provides estimates of the marginal impacts of those PV systems on home sale prices. This research analyzes a large dataset of California homes that sold from 2000 through mid-2009 with PV installed. We find strong evidence that homes with PV systems sold for a premium over comparable homes without PV systems during this time frame. Estimates for this premium expressed in dollars per watt of installed PV range, from roughly $4 to $6.4/watt across the full dataset, to approximately $2.3/watt for new homes, to more than $6/watt for existing homes. A number of ideas for further research are suggested.

Renewable Fuels Module (RFM) provides natural resources supply and technology input information for forecasts of new central-station U.S. electricity generating capacity using renewable energy resources. The RFM has seven submodules representing various renewable energy sources, biomass, geothermal, conventional hydroelectricity, landfill gas, solar thermal, solar photovoltaics, and wind108. Some renewables, such as landfill gas (LFG) from municipal solid waste (MSW) and other biomass materials, are fuels in the conventional sense of the word, while others, such as water, wind, and solar radiation, are energy sources that do not involve the production or consumption of a fuel. Renewable technologies cover the gamut of commercial market penetration, from hydroelectric power, which was one of the first electric generation technologies, to newer power systems using biomass, geothermal, LFG, solar, and wind energy. In some cases, they require technological innovation to become cost effective or have inherent characteristics, such as intermittency, which make their penetration into the electricity grid dependent upon new methods for integration within utility system plans or upon the availability of low-cost energy storage systems.

NV Energy Large-Scale Photovoltaic Integration Study: Intra-Hour Dispatch and AGC Simulation  

SciTech Connect

The uncertainty and variability with photovoltaic (PV) generation make it very challenging to balance power system generation and load, especially under high penetration cases. Higher reserve requirements and more cycling of conventional generators are generally anticipated for large-scale PV integration. However, whether the existing generation fleet is flexible enough to handle the variations and how well the system can maintain its control performance are difficult to predict. The goal of this project is to develop a software program that can perform intra-hour dispatch and automatic generation control (AGC) simulation, by which the balancing operations of a system can be simulated to answer the questions posed above. The simulator, named Electric System Intra-Hour Operation Simulator (ESIOS), uses the NV Energy southern system as a study case, and models the systems generator configurations, AGC functions, and operator actions to balance system generation and load. Actual dispatch of AGC generators and control performance under various PV penetration levels can be predicted by running ESIOS. With data about the load, generation, and generator characteristics, ESIOS can perform similar simulations and assess variable generation integration impacts for other systems as well. This report describes the design of the simulator and presents the study results showing the PV impacts on NV Energy real-time operations.

Increasing the solar photovoltaic energy capture on sunny and cloudy days  

Science Conference Proceedings (OSTI)

This report analyzes an extensive set of measurements of the solar irradiance made using four identical solar arrays and associated solar sensors (collectively referred to as solar collectors) with different tilt angles relative to the earth's surface, and thus the position of the sun, in order to determine an optimal tracking algorithm for capturing solar radiation. The study included a variety of ambient conditions including different seasons and both cloudy and cloud-free conditions. One set of solar collectors was always approximately pointed directly toward the sun (DTS) for a period around solar noon. These solar collectors thus captured the direct beam component of the solar radiation that predominates on sunny days. We found that on sunny days, solar collectors with a DTS configuration captured more solar energy in accordance with the well-known cosine dependence for the response of a flat-surfaced solar collector to the angle of incidence with direct beam radiation. In particular, a DTS orientation was found to capture up to twice as much solar energy as a horizontal (H) orientation in which the array is tilted toward the zenith. Another set of solar collectors always had an H orientation, and this best captured the diffuse component of the solar radiation that predominates on cloudy days. The dependence of the H/DTS ratio on the solar-collector tilt angle was in approximate agreement with the Isotropic Diffuse Model derived for heavily overcast conditions. During cloudy periods, we found that an H configuration increased the solar energy capture by nearly 40% compared to a DTS configuration during the same period, and we estimate the solar energy increase of an H configuration over a system that tracks the obscured solar disk could reach 50% over a whole heavily-overcast day. On an annual basis the increase is predicted to be much less, typically only about 1%, because the contribution of cloudy days to the total annual solar energy captured by a photovoltaic system is small. These results are consistent with the solar tracking algorithm optimized for cloudy conditions that we proposed in an earlier report and that was based on a much smaller data set. Improving the harvesting of solar energy on cloudy days deserves wider attention due to increasing efforts to utilize renewable solar energy. In particular, increasing the output of distributed solar power systems on cloudy days is important to developing solar-powered home fueling and charging systems for hydrogen-powered fuel-cell electric and battery-powered vehicles, respectively, because it reduces the system size and cost for solar power systems that are designed to have sufficient energy output on the worst (cloudy) days.

An Analysis of the Effects of Photovoltaic Energy Systems on Residential Selling Prices in California.  

SciTech Connect

An increasing number of homes with existing photovoltaic (PV) energy systems have sold in the U.S., yet relatively little research exists that estimates the marginal impacts of those PV systems on the sales price. A clearer understanding of these effects might influence the decisions of homeowners, home buyers and PV home builders. This research analyzes a large dataset of California homes that sold from 2000 through mid-2009 with PV installed. Across a large number of hedonic and repeat sales model specifications and robustness tests, the analysis finds strong evidence that homes with PV systems sold for a premium over comparable homes without. The effects range, on average, from approximately $3.9 to $6.4 per installed watt (DC), with most models coalescing near $5.5/watt, which corresponds to a premium of approximately $17,000 for a 3,100 watt system. The research also shows that, as PV systems age, the premium enjoyed at the time of home sale decreases. Additionally, existing homes with PV systems are found to have commanded a larger sales price premium than new homes with similarly sized PV systems. Reasons for this discrepancy are suggested, yet further research is warranted in this area as well as a number of other areas that are highlighted.

An Analysis of the Effects of Residential Photovoltaic Energy Systems on Home Sales Prices in California  

Science Conference Proceedings (OSTI)

An increasing number of homes in the U.S. have sold with photovoltaic (PV) energy systems installed at the time of sale, yet relatively little research exists that estimates the marginal impacts of those PV systems on home sale prices. A clearer understanding of these possible impacts might influence the decisions of homeowners considering the installation of a PV system, homebuyers considering the purchase of a home with PV already installed, and new home builders considering including PV as an optional or standard product on their homes. This research analyzes a large dataset of California homes that sold from 2000 through mid-2009 with PV installed. It finds strong evidence that homes with PV systems sold for a premium over comparable homes without PV systems during this time frame. Estimates for this premium expressed in dollars per watt of installed PV range, on average, from roughly $4 to $5.5/watt across a large number of hedonic and repeat sales model specifications and robustness tests. When expressed as a ratio of the sales price premium of PV to estimated annual energy cost savings associated with PV, an average ratio of 14:1 to 19:1 can be calculated; these results are consistent with those of the more-extensive existing literature on the impact of energy efficiency on sales prices. When the data are split among new and existing homes, however, PV system premiums are markedly affected. New homes with PV show premiums of $2.3-2.6/watt, while existing homes with PV show premiums of more than $6/watt. Reasons for this discrepancy are suggested, yet further research is warranted. A number of other areas where future research would be useful are also highlighted.

Photovoltaic energy program overview, fiscal year 1991. Programs in utility technologies  

SciTech Connect

The Photovoltaics Program Plan, FY 1991--FY 1995 builds on the accomplishments of the past 5 years and broadens the scope of program activities for the future. The previous plan emphasized materials and PV cell research. Under the balanced new plan, the PV Program continues its commitment to strategic research and development (R&D) into PV materials and processes, while also beginning work on PV systems and helping the PV industry encourage new markets for photovoltaics. A major challenge for the program is to assist the US PV industry in laying the foundation for at least 1000 MW of installed PV capacity in the United States and 500 MW internationally by 2000. As part of the new plan, the program expanded the scope of its activities in 1991. The PV Program is now addressing many new aspects of developing and commercializing photovoltaics. It is expanding activities with the US PV industry through the PV Manufacturing Technology (PVMaT) project, designed to address US manufacturers` immediate problems; providing technical assistance to potential end users such as electric utilities; and the program is turning its attention to encouraging new markets for PV. In 1991, for example, the PV Program initiated a new project with the PV industry to encourage a domestic market for PV applications in buildings and began cooperative ventures to support other countries such as Mexico to use PV in their rural electrification programs. This report reviews some of the development, fabrication and manufacturing advances in photovoltaics this year.

Evaluation of a photovoltaic energy mechatronics system with a built-in quadratic maximum power point tracking algorithm  

SciTech Connect

The historically high cost of crude oil price is stimulating research into solar (green) energy as an alternative energy source. In general, applications with large solar energy output require a maximum power point tracking (MPPT) algorithm to optimize the power generated by the photovoltaic effect. This work aims to provide a stand-alone solution for solar energy applications by integrating a DC/DC buck converter to a newly developed quadratic MPPT algorithm along with its appropriate software and hardware. The quadratic MPPT method utilizes three previously used duty cycles with their corresponding power outputs. It approaches the maximum value by using a second order polynomial formula, which converges faster than the existing MPPT algorithm. The hardware implementation takes advantage of the real-time controller system from National Instruments, USA. Experimental results have shown that the proposed solar mechatronics system can correctly and effectively track the maximum power point without any difficulties. (author)

Synthesis of Titanium Dioxide Hetero-Structures for Photovoltaic Energy Conversion  

E-Print Network (OSTI)

The photovoltaic energy conversion system (PV cells or solar cells) has been researched over the last few decades, and new technologies have been proposed. At the same time, the synthesis of nano-scale materials has been investigated intensively from the 1990s. These new types of materials encourage the development of new PV technologies with extensive research. Dye-sensitized solar cells (DSSCs) can be a part of these efforts. Since first presented in 1991, DSSCs have become the center of attention due to their great advantages to the traditional silicon solar cells. However, it remains a challenge to develop better performing DSSCs since the efficiency of DSSCs is still much lower than that of high performance solar cells. To meet this challenge, the different types of TiO2 nanostructures in DSSCs have been studied. This thesis presents the synthesis of TiO2 hetero-structures. These structures can achieve two important factors in DSSCs. One is the electron pathway for high electron transport rate, and the other is the large surface area for the dye absorption. TiO2 hetero-structures were successfully synthesized by using a simple thermal annealing method. The synthesis method required neither a high reaction temperature nor complicated reaction processes and produced dense TiO2 nanowires and incorporating TiO2 nanoparticles with relatively short reaction time. The key parameters of growing 1-D TiO2 nanostructures were the Cu eutectic catalyst, the reaction temperatures, and the annealing time. The repetition time and the reaction temperatures were important factors for incorporating TiO2 nanoparticles. The structure and composition of as-grown samples were analyzed using an x-ray diffractometer, a scanning electron microscope, a field emission scanning electron microscope, a transmission electron microscope and an ultraviolet-visible spectroscopy. The results showed they were crystalline structures in rutile phase of TiO2. From this research, we can utilize hetero-structures as an electrode of DSSCs. We also expect that our simple and effective synthesis method can be used for growing other kinds of metal oxide nanostructures, especially for those melting temperature are high.

A Study of United States Hydroelectric Plant Ownership  

Science Conference Proceedings (OSTI)

Ownership of United States hydroelectric plants is reviewed from several perspectives. Plant owners are grouped into six owner classes as defined by the Federal Energy Regulatory Commission. The numbers of plants and the corresponding total capacity associated with each owner class are enumerated. The plant owner population is also evaluated based on the number of owners in each owner class, the number of plants owned by a single owner, and the size of plants based on capacity ranges associated with each owner class. Plant numbers and corresponding total capacity associated with owner classes in each state are evaluated. Ownership by federal agencies in terms of the number of plants owned by each agency and the corresponding total capacity is enumerated.

Health, safety and environmental issues relating to cadmium usage in photovoltaic energy systems  

DOE Green Energy (OSTI)

This paper discusses the current technology base and hazards associated with two promising thin-film photovoltaic cells that contain cadmium compounds--cadmium telluride (CdTe) and copper indium deselenide (CuInSe{sub 2}). More specifically, this paper summarized the toxicological information on cadmium (Cd) compounds;evaluates potential health, safety and environmental hazards associated with cadmium usage in the photovoltaics industry; describes regulatory requirements associated with the use, handling and disposal of cadmium compounds; and lists management options to permit the safe and continued use of these materials. Handling of cadmium in photovoltaic production can present hazards to health, safety and the environment. Prior recognition of these hazards can allow device manufacturers and regulators to implement appropriate and readily available hazard management strategies. Hazards associated with product use (i.e., array fires) and disposal remain controversial and partially unresolved. The most likely effects that could be expected would be those associated with chronic low-level exposures to cadmium wastes. Because of the general immobility of the cadmium present in these devices and availability of environmental and biomonitoring protocols, chronic hazards can be monitored, and remediated if necessary. 26 refs., 5 figs., 2 tabs.

Mission analysis of photovoltaic solar energy conversion. Volume IV. Supplementary studies  

DOE Green Energy (OSTI)

A discussion is presented of the most significant problems associated with the production and deployment of photovoltaic arrays. The principal chemical compounds to be used in the manufacture of silicon, gallium arsenide, and cadmium sulfide photovoltaic arrays are discussed with respect to physical and chemical properties, sources of the raw materials required to extract or synthesize these materials, the methods of manufacture, storage and handling in large quantities, transportation restrictions, spills, leaks, ignition and explosion. A discussion of safety hazards associated with the finished products is followed by an analysis of the toxicological properties of all raw, refined, and finished chemical species involved. The principal tool used in the evaluation of incentive strategies was a new Public Utility Financial Analysis and Planning Model which is described in some detail. After adaptation to match the characteristics of photovoltaic plants, it was used in the comparative evaluation of six different incentive strategies. The candidate strategies, the rationale for their selection, and the results of the comparative evaluation are presented. An account is given of an attempt to assess the full non-internalized costs of coal-fired power generation. A detailed description is given of the various damage elements and their associated societal costs for coal production, coal transportation, and coal-fired power generation. (MHR)

Renewable Fuels Module Renewable Fuels Module Assumptions to the Annual Energy Outlook 2009 Renewable Fuels Module The NEMS Renewable Fuels Module (RFM) provides natural resources supply and technology input information for projections of new central-station U.S. electricity generating capacity using renewable energy resources. The RFM has seven submodules representing various renewable energy sources, biomass, geothermal, conventional hydroelectricity, landfill gas, solar thermal, solar photovoltaics, and wind1. Some renewables, such as landfill gas (LFG) from municipal solid waste (MSW) and other biomass materials, are fuels in the conventional sense of the word, while others, such as water, wind, and solar radiation, are energy sources that do not involve the production or consumption of a fuel. Renewable technologies cover the gamut of commercial market penetration, from hydroelectric power, which was one of the first electric generation technologies, to newer power systems using biomass, geothermal, LFG, solar, and wind energy.

Comparison of Energy Production and Performance from Flat-Plate Photovoltaic Module Technologies Deployed at Fixed Tilt: Preprint  

DOE Green Energy (OSTI)

This conference paper describes the performance data for 14 photovoltaic modules deployed at fixed-latitude tilt in the field are presented and compared. Module performance is monitored continuously for optimum power characteristics. Flat-plate module technologies representative of crystalline, amorphous, and polycrystalline silicon, and cadmium telluride and copper indium diselenide, are scrutinized for energy production, effective efficiency and performance ratio-ratio of effective to reference efficiency. Most performance ratios exhibit seasonal fluctuations largely correlated to air or module temperatures, varying between 80% and 100%. These ratios tend toward larger values during winter and vise versa, except for amorphous silicon and cadmium telluride modules. In a-Si cases, the situation appears reversed: better performance ratios are exhibited during late summer. The effective efficiency and average daily and yearly energy production are analyzed and quantified.

Environmental mitigation at hydroelectric projects. Volume 2, Benefits and costs of fish passage and protection  

DOE Green Energy (OSTI)

This study examines envirorunental mitigation practices that provide upstream and downstream fish passage and protection at hydroelectric projects. The study includes a survey of fish passage and protection mitigation practices at 1,825 hydroelectric plants regulated by the Federal Energy Regulatory Commission (FERC) to determine frequencies of occurrence, temporal trends, and regional practices based on FERC regions. The study also describes, in general terms, the fish passage/protection mitigation costs at 50 non-Federal hydroelectric projects. Sixteen case studies are used to examine in detail the benefits and costs of fish passage and protection. The 16 case studies include 15 FERC licensed or exempted hydroelectric projects and one Federally-owned and-operated hydroelectric project. The 16 hydroelectric projects are located in 12 states and range in capacity from 400 kilowatts to 840 megawatts. The fish passage and protection mitigation methods at the case studies include fish ladders and lifts, an Eicher screen, spill flows, airburst-cleaned inclined and cylindrical wedgewire screens, vertical barrier screens, and submerged traveling screens. The costs, benefits, monitoring methods, and operating characteristics of these and other mitigation methods used at the 16 case studies are examined.

Jackson Bluff Hydroelectric Project. Feasibility assessment report  

DOE Green Energy (OSTI)

A feasibility assessment study was conducted to determine if it is economical to reinstall hydroelectric generating units at the existing Jackson Bluff Dam on the Ochlockonee River in Florida. The studies and investigations have included site reconnaissance, system loads, growth rate, site hydrology, conceptual project arrangements and layouts, power output, estimates of construction costs and annual costs, economic analyses, development of a design and construction schedule and a preliminary environmental review of the proposed Project. It was concluded that the Project poses no unusual technical problems and no significant adverse environmental effects are anticipated. It shows sufficient promise of technical, economic and financial feasibility, to justify the City entering into the next phase of work, the FERC License Application, as soon as possible. The site can be restored for an investment of $9.9 to $10.4 million to establish 8.8 MW of capacity and produce 24,920 MWh of electrical energy annually, and in 10 years would save over $4 million as compared with current fuel costs for operating an oil-fueled power plant.

Hoopa Valley Small Scale Hydroelectric Feasibility Project  

Science Conference Proceedings (OSTI)

This study considered assessing the feasibility of developing small scale hydro-electric power from seven major tributaries within the Hoopa Valley Indian Reservation of Northern California (http://www.hoopa-nsn.gov/). This study pursued the assessment of seven major tributaries of the Reservation that flow into the Trinity River. The feasibility of hydropower on the Hoopa Valley Indian Reservation has real potential for development and many alternative options for project locations, designs, operations and financing. In order to realize this opportunity further will require at least 2-3 years of intense data collection focusing on stream flow measurements at multiple locations in order to quantify real power potential. This also includes on the ground stream gradient surveys, road access planning and grid connectivity to PG&E for sale of electricity. Imperative to this effort is the need for negotiations between the Hoopa Tribal Council and PG&E to take place in order to finalize the power rate the Tribe will receive through any wholesale agreement that utilizes the alternative energy generated on the Reservation.

Public health issues in photovoltaic energy systems: An overview of concerns  

SciTech Connect

Photovoltaic cell fabrication facilities may adversely affect public health by emitting pollutants during routine operation or by accidental events. The most important hazards probably relate to accidental releases of toxic or flammable gases used in large quantities in thin-film photovoltaic cell production. The most efficient strategies for reducing gas risks is to choose material and process options which inherently possess small risks, and to prevent accident initiating events. If accidents do occur, strategies to prevent catastrophic releases, to control releases and to prevent public exposures to toxic agents become important. Prevention and mitigation of consequences form the final defensive barriers. Homeowners who have small decentralized arrays may be at increased risk to fire and electric shock hazards. Manufacturers should carefully consider design engineering measures to prevent events, to prevent exposures, and to prevent consequences. If industry approaches these issues and mitigation strategies in a systematic way, liability and risk to industry and to the public should be minimized. 18 refs., 1 fig., 5 tabs.

Monolithic, multi-bandgap, tandem, ultra-thin, strain-counterbalanced, photovoltaic energy converters with optimal subcell bandgaps  

SciTech Connect

Modeling a monolithic, multi-bandgap, tandem, solar photovoltaic converter or thermophotovoltaic converter by constraining the bandgap value for the bottom subcell to no less than a particular value produces an optimum combination of subcell bandgaps that provide theoretical energy conversion efficiencies nearly as good as unconstrained maximum theoretical conversion efficiency models, but which are more conducive to actual fabrication to achieve such conversion efficiencies than unconstrained model optimum bandgap combinations. Achieving such constrained or unconstrained optimum bandgap combinations includes growth of a graded layer transition from larger lattice constant on the parent substrate to a smaller lattice constant to accommodate higher bandgap upper subcells and at least one graded layer that transitions back to a larger lattice constant to accommodate lower bandgap lower subcells and to counter-strain the epistructure to mitigate epistructure bowing.

Photovoltaic Materials  

Science Conference Proceedings (OSTI)

The goal of the current project was to help make the US solar industry a world leader in the manufacture of thin film photovoltaics. The overall approach was to leverage ORNLs unique characterization and processing technologies to gain a better understanding of the fundamental challenges for solar cell processing and apply that knowledge to targeted projects with industry members. ORNL has the capabilities in place and the expertise required to understand how basic material properties including defects, impurities, and grain boundaries affect the solar cell performance. ORNL also has unique processing capabilities to optimize the manufacturing process for fabrication of high efficiency and low cost solar cells. ORNL recently established the Center for Advanced Thin-film Systems (CATS), which contains a suite of optical and electrical characterization equipment specifically focused on solar cell research. Under this project, ORNL made these facilities available to industrial partners who were interested in pursuing collaborative research toward the improvement of their product or manufacturing process. Four specific projects were pursued with industrial partners: Global Solar Energy is a solar industry leader in full scale production manufacturing highly-efficient Copper Indium Gallium diSelenide (CIGS) thin film solar material, cells and products. ORNL worked with GSE to develop a scalable, non-vacuum, solution technique to deposit amorphous or nanocrystalline conducting barrier layers on untextured stainless steel substrates for fabricating high efficiency flexible CIGS PV. Ferro Corporations Electronic, Color and Glass Materials (ECGM) business unit is currently the worlds largest supplier of metallic contact materials in the crystalline solar cell marketplace. Ferros ECGM business unit has been the world's leading supplier of thick film metal pastes to the crystalline silicon PV industry for more than 30 years, and has had operational cells and modules in the field for 25 years. Under this project, Ferro leveraged world leading analytical capabilities at ORNL to characterize the paste-to-silicon interface microstructure and develop high efficiency next generation contact pastes. Ampulse Corporation is developing a revolutionary crystalline-silicon (c-Si) thin-film solar photovoltaic (PV) technology. Utilizing uniquely-textured substrates and buffer materials from the Oak Ridge National Laboratory (ORNL), and breakthroughs in Hot-Wire Chemical Vapor Deposition (HW-CVD) techniques in epitaxial silicon developed at the National Renewable Energy Laboratory (NREL), Ampulse is creating a solar technology that is tunable in silicon thickness, and hence in efficiency and economics, to meet the specific requirements of multiple solar PV applications. This project focused on the development of a high rate deposition process to deposit Si, Ge, and Si1-xGex films as an alternate to hot-wire CVD. Mossey Creek Solar is a start-up company with great expertise in the solar field. The primary interest is to create and preserve jobs in the solar sector by developing high-yield, low-cost, high-efficiency solar cells using MSC-patented and -proprietary technologies. The specific goal of this project was to produce large grain formation in thin, net-shape-thickness mc-Si wafers processed with high-purity silicon powder and ORNL's plasma arc lamp melting without introducing impurities that compromise absorption coefficient and carrier lifetime. As part of this project, ORNL also added specific pieces of equipment to enhance our ability to provide unique insight for the solar industry. These capabilities include a moisture barrier measurement system, a combined physical vapor deposition and sputtering system dedicated to cadmium-containing deposits, adeep level transient spectroscopy system useful for identifying defects, an integrating sphere photoluminescence system, and a high-speed ink jet printing system. These tools were combined with others to study the effect of defects on the performance of crystalline silicon and

Simulations of the energy performance of a solar photovoltaic residence and hybrid electric automobile in Fresno, California  

Science Conference Proceedings (OSTI)

The hour-by-hour energy performance of a photovoltaic residence and hybrid electric vehicle system that could be built with 1980s' technology is analyzed. Thermal and electrical performance in both stand-alone and grid-connected configurations were simulated with computer models using actual hourly solar and weather data for Fresno, California. The system centers around an energy-efficient residence that incorporates passive heating and cooling. For the simulations in this study, 110 square meters of GE photovoltaic shingle modules (9.6 kW(e) rated power), a 10 kW(e) dc-ac inverter, and advanced lead-acid batteries of 61 kWh(e) capacity were added to the residence. The auto has 30 kWh(e) of lead-acid batteries and a 40-hp electric drive motor for propulsion. The auto was assumed to travel 100 km (62 miles) each day (36,500 km (22,680 miles) annually). A small (10 kW(e)) backup liquid-fueled engine/generator in the auto provides supplemental electricity on cloudy days and for long-distance travel. The utility would provide backup electricity for the residence, or the auto engine/generator can provide this backup power to the residence as well as so-called waste heat from the engine for space heating and domestic hot water. Year-round heating and cooling needs are met primarily with passive design features, and most hot water comes from a solar water heater. The PV array meets all the electrical loads of the residence on 315 days and part of the load on the other 50 days. The PV array also meets the entire auto electricity load on 166 days, and part of the load on another 116 days. A brief cost analysis indicates that both stand-alone and grid-connected systems would be competitive with grid electricity and conventional autos within this decade.

Comprehensive energy-management program. Hybrid photovoltaic/thermal absorber. Annual report, September 1, 1980-December 31, 1981  

DOE Green Energy (OSTI)

Research work was done during the reporting period on the two-part research program: (A) to improve energy conservation through increased unit and system efficiencies, energy management, and system optimization, and (B) to develop a novel, low-cost hybrid photovoltaic/thermal absorber. Performance tests were conducted on all the boilers and chillers on campus. Several corrective measures were indicated and implemented. A detailed survey of energy use by functions and consumption/demand study has been in progress. A preliminary computer simulation model of the entire campus has been developed and made operational. It has been demonstrated both analytically and experimentally that the reradiation losses from the absorber can be reduced significantly by utilizing a light-pipe absorber. Two paraboloidal dishes, one of 6 ft diameter and the other of 20 ft diameter have been utilized. Collector efficiencies have been measured at coolant outlet temperatures up to 282/sup 0/C with a square light-pipe absorber and with 6 ft diameter concentrator. Laser ray testing was conducted on both the 6 ft and 20 ft diameter concentrators. Design of the total energy absorber has been completed.

Photovoltaics is a technology that converts radiant Photovoltaics is a technology that converts radiant light energy (photo) to electricity (voltaics). Photo- voltaic (PV) cells are the basic building blocks of this energy technology. PV cells (also called solar cells) are made of semicon- ductor materials, most typically silicon. The amount of electricity a PV cell produces depends on its size, its conversion efficiency (see box on reverse), and the intensity of the light source. Sunlight is the most common source of the energy used by PV cells to produce an electric current. It takes just a few PV cells to produce enough elec- tricity to power a small watch or solar calculator. For more power, cells are connected together to form larger units called modules. Modules, in turn, are connected to form arrays, and arrays can be
