Desert Sunlight is Shining Example of How DOE Loan Guarantees Helped Launch Utility-scale PV Solar Market  

Broader source: Energy.gov [DOE]

LPO helped finance the first five utility-scale PV projects larger than 100 MW in the U.S. With Desert Sunlight now fully operational, all five projects are online, generating clean electricity and repaying loans. The initial investments made by LPO helped build a market that subsequently financed an additional 17 projects larger than 100 MW without help from the Department.

Experimenting with concentrated sunlight using the DLR solar furnace  

SciTech Connect (OSTI)

The high flux solar furnace that is operated by the Deutsche Forschungsanstalt fuer Luft- und Raumfahrt (DLR) at Cologne was inaugurated in June 1994 and we are now able to look back onto one year of successful operation. The solar furnace project was founded by the government of the State Northrhine Westfalia within the Study Group AG Solar. The optical design is a two-stage off-axis configuration which uses a flat 52 m{sup 2} heliostat and a concentrator composed of 147 spherical mirror facets. The heliostat redirects the solar light onto the concentrator which focuses the beam out of the optical axis of the system into the laboratory building. At high insolation levels (>800W/m{sup 2}) it is possible to collect a total power of 20 kW with peak flux densities of 4 MW/m{sup 2}. Sixteen different experiment campaigns were carried out during this first year of operation. The main research fields for these experiments were material science, component development and solar chemistry. The furnace also has its own research program leading to develop sophisticated measurement techniques like remote infrared temperature sensing and flux mapping. Another future goal to be realized within the next five years is the improvement of the performance of the furnace itself. 6 refs., 9 figs., 1 tab.

Correction of the concentrated sunlight spot's drift of the IER-UNAM's solar furnace  

Science Journals Connector (OSTI)

Abstract This paper discusses the methods implemented for the solution of the drift and backlash problems in the heliostat of the High Radiative Flux Solar Furnace recently built at the Renewable Energy Institute (former Center for Energy Research) of the National University of Mexico (IER-UNAM), located at the geographical coordinates 1850?24? North latitude and 9915?00? West longitude. To solve the observed drift, several algorithms were analyzed for the calculation of the solar vector, and a closed loop through an electronic device (peephole) was implemented which makes corrections to the position of the heliostat. Using the peephole, drift heliostat decreased significantly; 70% in the horizontal direction and 63% in the vertical direction relative to the no use of peephole. The backlash was corrected by means of unbalancing the heliostat.

Solar powered induction motor-driven water pump operating on a desert well, simulation and field tests  

Science Journals Connector (OSTI)

A photovoltaic-powered water pumping system, employing an induction motor pump, capable of supplying a daily average of 50m3 at 37-m head has been developed. The system was installed on a desert well in Jordan, where: the average solar radiation amount to 5.5kWh/m3/day, to provide the Bedouins living in the well area with drinking water. A mathematical model to enable testing the system performance by computer simulation was developed. This model allows the representation of motor torque in function of speed (and slip) at different supply frequencies, as well as the flow rate and efficiency of the system in function of supply frequency and pumping head. Prior to its installation on the desert well, the system performance, in accordance with frequency and head, was thoroughly tested in the laboratory. As illustrated in this paper, simulation and laboratory testing results are well matched. At constant pumping head, the flow rate is proportional to the supply frequency of the motor. At constant flow rate, the pumping head is proportional to the supply frequency squared only in the range below the peak efficiency of the pump. For higher flow rate values, a special algorithm based on the experimental results could be developed. Higher system efficiency is achievable at higher frequency. It is advisable to operate the motor pump at the nominal frequency, flow rate and head corresponding to maximum efficiency. Long-term field testing of the system shows that it is reliable and has an overall efficiency exceeding 3%, which is comparable to the highest efficiencies reported elsewhere for solar powered pumps.

Dye?sensitized Solar Cells for Solar Energy Harvesting  

Science Journals Connector (OSTI)

Dye?sensitized solar cells (DSSCs) also known as Gratzel cells have attracted the interests of researchers to a great extent because of its cost effective and easy manufacturing process without involving highly sophisticated lithographic technique and high cost raw materials as usually seen in conventional solar cell. Based on simple photo?electrochemical process it has got immense potential in converting solar energy to electrical power in remote and desert area where the supply of conventional power is not possible. The overall peak power?production efficiency of dye?sensitized solar cells has been reported around 11 percent so they are best suited to low?density applications and the price?to?performance ratio obtained through these solar cells is superior to others. DSSCs have ability to absorb even diffused sunlight and therefore work in cloudy whether as well without much impact over the efficiency. The present communication deals with a review of our work on DSSCs wherein we have used cost effective natural dyes/pigments as a sensitizer of nc?TiO2 and discussed about various key factors affecting the conversion efficiency of DSSC.

Exploring Venus by solar airplane  

Science Journals Connector (OSTI)

A solar-powered airplane is proposed to explore the atmospheric environment of Venus. Venus has several advantages for a solar airplane. At the top of the cloud level the solar intensity is comparable to or greater than terrestrial solar intensities. The Earthlike atmospheric pressure means that the power required for flight is lower for Venus than that of Mars and the slow rotation of Venus allows an airplane to be designed for continuous sunlight with no energy storage needed for night-time flight. These factors mean that Venus is perhaps the easiest planet in the solar system for flight of a long-duration solar airplane.

(click on image for diagram portraying the water-splitting catalytic cycle) Scientific Highlight LBNL Press Release Physical Biosciences, LBNL 30 November 2006 Learning How Nature Splits Water (Condensed by Brad Plummer from a press release issued by Lawrence Berkeley National Laboratory) Billions of years ago, primitive bacteria developed a way to harness sunlight to split water molecules into protons, electrons and oxygen-the cornerstone of photosynthesis. Now, a team of scientists has taken a major step toward understanding this process by deriving the precise structure of the catalytic metal-cluster center containing four manganese atoms and one calcium atom (Mn4Ca) that drives this water-splitting reaction. This catalytic center resides in a large protein complex, called photosystem II, found in plants, green algae, and cyanobacteria. The international team was led by scientists from LBNL, and includes scientists from Germany's Technical and Free Universities in Berlin, the Max Planck Institute in Mülheim, and from SSRL.

The shallow water of a lake is usually warmer than the deep water. That's because the sunlight can heat the lake bottom in the shallow areas, which in turn, heats the water. It's nature's way of solar water heating. The sun can be used in basically the same way to heat water used in buildings and swimming pools. Most solar water heating systems for buildings have two main parts: a solar collector and a storage tank. The most common collector is called a flat-plate collector.

Chapter 3 - Oxidative Stress Induced by Air Pollution and Exposure to Sunlight  

Science Journals Connector (OSTI)

Air pollution contains small particles, and particles smaller than 10 ?m can generate free radicals when inhaled. In addition, various free radicals may also be present in polluted air. In general, the air quality of urban areas is poorer than that of rural areas. Industrial smoke also contains free radicals and small particles. Breathing polluted air for a long period of time may induce oxidative stress in the body, causing various illnesses including chronic obstructive pulmonary disease and lung cancer. Sunlight contains UV radiation, and prolonged exposure to sunlight or sunbathing without application of sunscreen may cause sunburn, skin damage, and even skin cancer including melanoma, which is linked to oxidative stress. During the summer months when the UV index is high, exposure to sunlight should be reduced or protective clothing should be worn. Moreover, use of sunglasses is recommended because UV light can induce oxidative stress in eyes, causing cataract formation and other eye diseases such as macular degeneration.

Science Journals Connector (OSTI)

The use of photovoltaic solar panels (and related generation of electric power) can be extended to a 24 hours per day under any environmental condition by equipping them with an artificial source of light with emitting wavelengths matched to the photovoltaic solar panels to be turned on in the absence of sunlight. This source of light can be obtained by heating a mantle to an incandescent temperature via the efficient low polluting combustion of Natural Gas Butane Propane or other gaseous Hydrocarbon fuel.

Solar Energy Resource Basics Solar Energy Resource Basics Solar Energy Resource Basics August 21, 2013 - 11:40am Addthis Solar radiation, often called the solar resource, is a general term for the electromagnetic radiation emitted by the sun. Solar radiation can be captured and turned into useful forms of energy, such as heat and electricity, using a variety of technologies. However, the technical feasibility and economical operation of these technologies at a specific location depends on the available solar resource. Basic Principles Every location on Earth receives sunlight at least part of the year. The amount of solar radiation that reaches any one spot on the Earth's surface varies according to: Geographic location Time of day Season Local landscape Local weather. Because the Earth is round, the sun strikes the surface at different

A Fully Integrated Nanosystem of Semiconductor Nanowires for Direct Solar Water Splitting  

SciTech Connect (OSTI)

Artificial photosynthesis, the biomimetic approach to converting sunlight?s energy directly into chemical fuels, aims to imitate nature by using an integrated system of nanostructures, each of which plays a specific role in the sunlight-to-fuel conversion process. Here we describe a fully integrated system of nanoscale photoelectrodes assembled from inorganic nanowires for direct solar water splitting. Similar to the photosynthetic system in a chloroplast, the artificial photosynthetic system comprises two semiconductor light absorbers with large surface area, an interfacial layer for charge transport, and spatially separated cocatalysts to facilitate the water reduction and oxidation. Under simulated sunlight, a 0.12percent solar-to-fuel conversion efficiency is achieved, which is comparable to that of natural photosynthesis. The result demonstrates the possibility of integrating material components into a functional system that mimics the nanoscopic integration in chloroplasts. It also provides a conceptual blueprint of modular design that allows incorporation of newly discovered components for improved performance.

Effects of biofilms, sunlight, and salinity on corrosion potential and corrosion initiation of stainless alloys  

SciTech Connect (OSTI)

This phenomenon of corrosion potential ennoblement on stainless alloys is well known for full strength seawater. This report presents data on the extent to which that process occurs as a function of salinity and sunlight level for: stainless steels S30400 and S31600; stainless alloys S44735 (29-4C), S44660 (Seacure), NO8367 (6XN) and N10276 (C-276); and R50250 (Ti-Gr2). The results showed that natural population biofilms formed from all salinity waters under low light level conditions were capable of ennobling the corrosion potentials of all test alloys, although R50250 was consistently ennobled the least. Both the amount of ennoblement and the highest steady potential reached were maximized in fresh water and decreased for all alloys with increasing salinity. The critical pitting potentials for all test alloys were measured in coastal seawater. In addition, the critical pitting potentials for alloys S30400 and S31600 were measured (or estimated from the literature) as a function of salinity. The effect of ennoblement on the initiation and propagation of crevice corrosion are currently under investigation. The effect of sunlight on corrosion potential ennoblement was examined for the super alloy N10276 (C-276). Mechanisms by which ennoblement may be affected by sunlight were discussed, and it was hypothesized that the phenomenon may be at least partially understood in terms of pH fluctuations within the biofilm under the influence of periodic changes in the rates of photosynthesis and respiration.

FEMP--Solar Water Heating  

Broader source: Energy.gov (indexed) [DOE]

More than 1 million homeowners and 200,000 busi- More than 1 million homeowners and 200,000 busi- nesses in the United States are using the sun to heat domestic water efficiently in almost any climate. In summer, a solar system properly sized for a resi- dential building can meet 100% of the building's water-heating needs in most parts of the country. In winter, the system might meet only half of this need, so another source of heat is used to back up the solar system. In either case, solar water heating helps to save energy, reduce utility costs, and preserve the environment. A solar water-heating system's performance depends primarily on the outdoor temperature, the temperature to which the water is heated, and the amount of sunlight striking the collector-the device that actually captures the sun's energy.

Mechanical controls slowly rotate the collectors during the day, keeping them aimed at the sun as it travels across the sky. Synthetic oil flowing through the receiver pipe serves as the heat transfer medium. The collectors concentrate sunlight 30 to 60 times the normal intensity on the receiver, heating the oil as high as 735°F (390°C).

Concentrating Solar Power Dish/Engine System Basics Concentrating Solar Power Dish/Engine System Basics Concentrating Solar Power Dish/Engine System Basics August 20, 2013 - 5:02pm Addthis The dish/engine system is a concentrating solar power (CSP) technology that produces relatively small amounts of electricity compared to other CSP technologies-typically in the range of 3 to 25 kilowatts. Dish/engine systems use a parabolic dish of mirrors to direct and concentrate sunlight onto a central engine that produces electricity. The two major parts of the system are the solar concentrator and the power conversion unit. Solar Concentrator Illustration of a dish/engine power plant. Sunlight is shown reflecting off the large dish-shaped concentrator and onto the mounted power conversion unit to generate electricity that is fed into the power grid. The system looks similar to a large satellite television receiver dish.

Solar?energy conversion at high solar intensities  

Science Journals Connector (OSTI)

The concentration of sunlight offers distinct advantages for solarelectrical generation either by thermal conversion or by photovoltaics. A large variety of concentration techniques are available with concentration ratios of 11000. Concentration is required for thermal conversion systems to attain the high temperatures needed for efficiencies in the desired range of about 25%35%. The projected costs for some of the solar thermal systems (especially the central receiver and the fixed mirror) indicate that they could be economically competitive in the southwestern states. The southwest may be required for these high?concentration systems to overcome the main disadvantage of concentration which is the use of the direct component of sunlight only. Other concerns of high?intensity systems are in tracking requirements reflective surface accuracy and material lifetimes of both the reflecting and absorbing components. Selective surface absorbers will be required for systems with concentration ratios below a few hundred. The present high cost of solar?cell?generated electricity can be reduced considerably by using concentrators. Cells can be used with any of the concentrator designs and the major concern is keeping them at acceptable operating temperatures. Planar silicon cells vertical multijunction and galliumaluminumarsenide cells all look attractive for concentrating systems.

Examining the feasibility of converting New York States all-purpose energy infrastructure to one using wind, water, and sunlight  

Science Journals Connector (OSTI)

This study analyzes a plan to convert New York State's (NYS's) all-purpose (for electricity, transportation, heating/cooling, and industry) energy infrastructure to one derived entirely from wind, water, and sunlight (WWS) generating electricity and electrolytic hydrogen. Under the plan, NYS's 2030 all-purpose end-use power would be provided by 10% onshore wind (4020 5-MW turbines), 40% offshore wind (12,700 5-MW turbines), 10% concentrated solar (387 100-MW plants), 10% solar-PV plants (828 50-MW plants), 6% residential rooftop PV (?5 million 5-kW systems), 12% commercial/government rooftop PV (?500,000 100-kW systems), 5% geothermal (36 100-MW plants), 0.5% wave (1910 0.75-MW devices), 1% tidal (2600 1-MW turbines), and 5.5% hydroelectric (6.6 1300-MW plants, of which 89% exist). The conversion would reduce NYS's end-use power demand ?37% and stabilize energy prices since fuel costs would be zero. It would create more jobs than lost because nearly all NYS energy would now be produced in-state. NYS air pollution mortality and its costs would decline by ?4000 (12007600) deaths/yr, and $33 (1076) billion/yr (3% of 2010 NYS GDP), respectively, alone repaying the 271GW installed power needed within ?17 years, before accounting for electricity sales. NYS's own emission decreases would reduce 2050 U.S. climate costs by ?$3.2 billion/yr.

Solar Thermal Energy Storage Device: Hybrid Nanostructures for High-Energy-Density Solar Thermal Fuels  

SciTech Connect (OSTI)

HEATS Project: MIT is developing a thermal energy storage device that captures energy from the sun; this energy can be stored and released at a later time when it is needed most. Within the device, the absorption of sunlight causes the solar thermal fuels photoactive molecules to change shape, which allows energy to be stored within their chemical bonds. A trigger is applied to release the stored energy as heat, where it can be converted into electricity or used directly as heat. The molecules would then revert to their original shape, and can be recharged using sunlight to begin the process anew. MITs technology would be 100% renewable, rechargeable like a battery, and emissions-free. Devices using these solar thermal fuelscalled Hybrisolcan also be used without a grid infrastructure for applications such as de-icing, heating, cooking, and water purification.

Solar Energy Generation in Three Dimensions

Optimizing the conversion of solar energy to electricity is central to the World's future energy economy. Flat photovoltaic panels are commonly deployed in residential and commercial rooftop installations without sun tracking systems and using simple installation guidelines to optimize solar energy collection. Large-scale solar energy generation plants use bulky and expensive sun trackers to avoid cosine losses from photovoltaic panels or to concentrate sunlight with mirrors onto heating fluids.[1,2] However, none of these systems take advantage of the three-dimensional nature of our biosphere, so that solar energy collection largely occurs on flat structures in contrast with what is commonly observed in Nature.[3,4] Here we formulate, solve computationally and study experimentally the problem of collecting solar energy in three-dimensions.[5] We demonstrate that absorbers and reflectors can be combined in the absence of sun tracking to build three-dimensional photovoltaic (3DPV) structures that can generate ...

Sorption of inositol hexaphosphate on desert soils  

Science Journals Connector (OSTI)

Abstract Sorption of inositol hexaphosphate (IP6) on desert soils was studied to evaluate their use as a novel low-cost sorbent material for organic P removal in water treatment. The kinetics of IP6 sorption, pH effects, and sorption isotherms were examined in batch experiments on four desert salinesodic soils: Antofagasta (AN), Mejillones (ME), Aguas Blancas I (ABI), and Aguas Blancas II (ABII). The sorption kinetics of inositol hexaphosphate expressed as P (P-IP6) on these soils were described by the Elovich equation and the initial sorption velocities ranked in the order: ABII>ABI>ME>AN. In addition, P-IP6 sorption capacity in AN, ME, and ABI was strongly influenced by the solution pH, but in ABII it was not pH-dependent. Whereas the experimental data of P-IP6 sorption on ME, ABI, and ABII were better fitted by the Langmuir equation (implying a homogenous distribution of active sorption sites), for AN the best fit was obtained with the Freundlich model (implying heterogeneous, multi-layered sorption surfaces). The maximum P-IP6 sorption capacities ranked: ABII>ME>AN>ABI. Based on the results of our study, ABII soil is recommended for P-IP6 removal. In this soil, P-IP6 sorption did not depend on solution pH, and the precipitation and sorption of IP6 were associated with Ca2+, Mg2+, and minerals such as montmorillonite and vermiculite.

RADIATIVE HEATING OF THE SOLAR CORONA  

SciTech Connect (OSTI)

We investigate the effect of solar visible and infrared radiation on electrons in the Sun's atmosphere using a Monte Carlo simulation of the wave-particle interaction and conclude that sunlight provides at least 40% and possibly all of the power required to heat the corona, with the exception of dense magnetic flux loops. The simulation uses a radiation waveform comprising 100 frequency components spanning the solar blackbody spectrum. Coronal electrons are heated in a stochastic manner by low coherence solar electromagnetic radiation. The wave 'coherence time' and 'coherence volume' for each component is determined from optical theory. The low coherence of solar radiation allows moving electrons to gain energy from the chaotic wave field which imparts multiple random velocity 'kicks' to these particles causing their velocity distribution to broaden or heat. Monte Carlo simulations of broadband solar radiative heating on ensembles of 1000 electrons show heating at per particle levels of 4.0 x 10{sup -21} to 4.0 x 10{sup -20} W, as compared with non-loop radiative loss rates of {approx}1 x 10{sup -20} W per electron. Since radiative losses comprise nearly all of the power losses in the corona, sunlight alone can explain the elevated temperatures in this region. The volume electron heating rate is proportional to density, and protons are assumed to be heated either by plasma waves or through collisions with electrons.

Optical Durability of Candidate Solar Reflectors for Concentrating Solar Power  

SciTech Connect (OSTI)

Concentrating solar power (CSP) technologies use large mirrors to collect sunlight to convert thermal energy to electricity. The viability of CSP systems requires the development of advanced reflector materials that are low in cost and maintain high specular reflectance for extended lifetimes under severe outdoor environments. The long-standing goals for a solar reflector are specular reflectance above 90% into a 4 mrad half-cone angle for at least 10 years outdoors with a cost of less than $13.8/m{sup 2} (the 1992 $10.8/m{sup 2} goal corrected for inflation to 2002 dollars) when manufactured in large volumes. Durability testing of a variety of candidate solar reflector materials at outdoor test sites and in laboratory accelerated weathering chambers is the main activity within the Advanced Materials task of the CSP Program at the National Renewable Energy Laboratory (NREL) in Golden, Colorado. Test results to date for several candidate solar reflector materials will be presented. These include the optical durability of thin glass, thick glass, aluminized reflectors, front-surface mirrors, and silvered polymer mirrors. The development, performance, and durability of these materials will be discussed. Based on accelerated exposure testing the glass, silvered polymer, and front-surface mirrors may meet the 10 year lifetime goals, but at this time because of significant process changes none of the commercially available solar reflectors and advanced solar reflectors have demonstrated the 10 year or more aggressive 20 year lifetime goal.

Broader source: All U.S. Department of Energy (DOE) Office Webpages (Extended Search)

solar reflectance-Part I: Defining a metric that accurately solar reflectance-Part I: Defining a metric that accurately predicts solar heat gain Title Measuring solar reflectance-Part I: Defining a metric that accurately predicts solar heat gain Publication Type Journal Article Year of Publication 2010 Authors Levinson, Ronnen M., Hashem Akbari, and Paul Berdahl Journal Solar Energy Volume 84 Pagination 1717-1744 Keywords Heat Island, Methods & Protocols Abstract Solar reflectance can vary with the spectral and angular distributions of incident sunlight, which in turn depend on surface orientation, solar position and atmospheric conditions. A widely used solar reflectance metric based on the ASTM Standard E891 beam-normal solar spectral irradiance underestimates the solar heat gain of a spectrally selective "cool colored" surface because this irradiance contains a greater fraction of near-infrared light than typically found in ordinary (unconcentrated) global sunlight. At mainland US latitudes, this metric RE891BN can underestimate the annual peak solar heat gain of a typical roof or pavement (slope 5:12 [23°]) by as much as 89 W m-2, and underestimate its peak surface temperature by up to 5 K. Using RE891BN to characterize roofs in a building energy simulation can exaggerate the economic value N of annual cool roof net energy savings by as much as 23%.

Sunlight-Driven Hydrogen Formation by Membrane-Supported Photoelectrochemical Water Splitting  

SciTech Connect (OSTI)

This report describes the significant advances in the development of the polymer-supported photoelectrochemical water-splitting system that was proposed under DOE grant number DE-FG02-05ER15754. We developed Si microwire-array photoelectrodes, demonstrated control over the material and light-absorption properties of the microwire-array photoelectrodes, developed inexpensive processes for synthesizing the arrays, and doped the arrays p-type for use as photocathodes. We also developed techniques for depositing metal-nanoparticle catalysts of the hydrogen-evolution reaction (HER) on the wire arrays, investigated the stability and catalytic performance of the nanoparticles, and demonstrated that Ni-Mo alloys are promising earth-abundant catalysts of the HER. We also developed methods that allow reuse of the single-crystalline Si substrates used for microwire growth and methods of embedding the microwire photocathodes in plastic to enable large-scale processing and deployment of the technology. Furthermore we developed techniques for controlling the structure of WO3 films, and demonstrated that structural control can improve the quantum yield of photoanodes. Thus, by the conclusion of this project, we demonstrated significant advances in the development of all components of a sunlight-driven membrane-supported photoelectrochemical water-splitting system. This final report provides descriptions of some of the scientific accomplishments that were achieved under the support of this project and also provides references to the peer-reviewed publications that resulted from this effort.

Computational study of atmospheric transfer radiation on an equatorial tropical desert (La Tatacoa, Colombia)  

E-Print Network [OSTI]

Radiative transfer models explain and predict interaction between solar radiation and the different elements present in the atmosphere, which are responsible for energy attenuation. In Colombia there have been neither measurements nor studies of atmospheric components such as gases and aerosols that can cause turbidity and pollution. Therefore satellite images cannot be corrected radiometrically in a proper way. When a suitable atmospheric correction is carried out, loss of information is avoided, which may be useful for discriminating image land cover. In this work a computational model was used to find radiative atmospheric attenuation (300 1000nm wavelength region) on an equatorial tropical desert (La Tatacoa, Colombia) in order to conduct an adequate atmospheric correction.

Realizing InGaN monolithic solar-photoelectrochemical cells for artificial photosynthesis  

SciTech Connect (OSTI)

InGaN alloys are very promising for solar water splitting because they have direct bandgaps that cover almost the whole solar spectrum. The demonstration of direct solar-to-fuel conversion without external bias with the sunlight being the only energy input would pave the way for realizing photoelectrochemical (PEC) production of hydrogen by using InGaN. A monolithic solar-PEC cell based on InGaN/GaN multiple quantum wells capable to directly generate hydrogen gas under zero bias via solar water splitting is reported. Under the irradiation by a simulated sunlight (1-sun with 100 mW/cm{sup 2}), a 1.5% solar-to-fuel conversion efficiency has been achieved under zero bias, setting a fresh benchmark of employing III-nitrides for artificial photosynthesis. Time dependent hydrogen gas production photocurrent measured over a prolonged period (measured for 7 days) revealed an excellent chemical stability of InGaN in aqueous solution of hydrobromic acid. The results provide insights into the architecture design of using InGaN for artificial photosynthesis to provide usable clean fuel (hydrogen gas) with the sunlight being the only energy input.

Concentrating Solar Power Basics (The following text is derived from NREL's concentrating solar power information page.)[1] Concentrating solar power (CSP) offers a utility-scale, firm, dispatchable renewable energy option that can help meet our nation's demand for electricity. CSP plants produce power by first using mirrors to focus sunlight to heat a working fluid. Ultimately, this high-temperature fluid is used to spin a turbine or power an engine that drives a generator. And the final product is electricity. Smaller CSP systems can be located directly where the power is needed. Larger, utility-scale CSP applications provide hundreds of megawatts of electricity for the power grid. Both linear concentrator and power tower systems can be easily integrated with thermal storage, helping to generate

A laser beam apparatus and method for analyzing, inter alia, the current versus voltage curve at the point of illumination on a solar cell and the open circuit voltage of a solar cell. The apparatus incorporates a lock-in amplifier, and a laser beam light chopper which permits the measurement of the AC current of the solar cell at an applied DC voltage at the position on the solar cell where the cell is illuminated and a feedback scheme which permits the direct scanning measurements of the open circuit voltage. The accuracy of the measurement is a function of the intensity and wavelength of the laser light with respect to the intensity and wavelength distribution of sunlight and the percentage the dark current is at the open circuit voltage to the short circuit current of the solar cell.

Advances in Measuring Solar Reflectance-or, Why That Roof isn't as Cool Advances in Measuring Solar Reflectance-or, Why That Roof isn't as Cool as You Thought it Was Speaker(s): Ronnen Levinson Date: June 30, 2009 - 12:00pm Location: LBNL Bldg. 66 Auditorium Solar reflectance is often used to estimate the solar heat gain and rate the "coolness" of roofs and pavements. A solar reflectance property measured by two popular ASTM standard test methods (E903, C1549) can underestimate the peak solar heat gain of a spectrally selective "cool colored" surface by nearly 100 W m-2 because it assumes that sunlight contains an unrealistically high fraction of near-infrared (invisible) energy. Its use in building energy simulations can overestimate cool-roof annual energy savings by more than 20%. I define a new and simple solar

Wouldn't it be nice to capture more of that intense sunlight and convert it into electricity? Modern photovoltaic cells (more commonly known as solar panels) were invented in the 1950s at Bell Laboratories. But despite the passage of over fifty years, solar energy's full potential has yet to be tapped due in part to the cost of actually putting the pieces of a solar panel together -- installing solar panels still far exceeds the cost of using traditional

Award-Winning Etching Process Cuts Solar Cell Costs (Fact Sheet)  

SciTech Connect (OSTI)

NREL scientists have invented the 'black silicon' nanocatalytic wet-chemical etch, an inexpensive, one-step process that literally turns the solar cells black, allowing them to absorb more than 98% of incident sunlight. The process costs just a few cents per watt of solar-cell power-producing capacity. Increases in manufactured cell efficiencies of up to 0.8% are possible because of the reduced reflectance of black silicon. This would reduce silicon solar module costs by $5-$10 per module.

Slow light enhanced singlet exciton fission solar cells with a 126% yield of electrons per photon  

SciTech Connect (OSTI)

Singlet exciton fission generates two triplet excitons per absorbed photon. It promises to increase the power extracted from sunlight without increasing the number of photovoltaic junctions in a solar cell. We demonstrate solar cells with an external quantum efficiency of 126% by enhancing absorption in thin films of the singlet exciton fission material pentacene. The device structure exploits the long photon dwell time at the band edge of a distributed Bragg reflector to achieve enhancement over a broad range of angles. Measuring the reflected light from the solar cell establishes a lower bound of 137% for the internal quantum efficiency.

Broader source: Energy.gov (indexed) [DOE]

Concentrating Solar Power Tower System Basics Concentrating Solar Power Tower System Basics Concentrating Solar Power Tower System Basics August 20, 2013 - 5:06pm Addthis In power tower concentrating solar power systems, numerous large, flat, sun-tracking mirrors, known as heliostats, focus sunlight onto a receiver at the top of a tall tower. A heat-transfer fluid heated in the receiver is used to generate steam, which, in turn, is used in a conventional turbine generator to produce electricity. Some power towers use water/steam as the heat-transfer fluid. Other advanced designs are experimenting with molten nitrate salt because of its superior heat-transfer and energy-storage capabilities. Individual commercial plants can be sized to produce up to 200 megawatts of electricity. Illustration of a power tower power plant. Sunlight is shown reflecting off a series of heliostats surrounding the tower and onto the receiver at the top of the tower. The hot heat-transfer fluid exiting from the receiver flows down the tower, into a feedwater reheater, and then into a turbine, which generates electricity that is fed into the power grid. The cool heat-transfer fluid exiting the turbine flows into a steam condenser to be cooled and sent back up the tower to the receiver.

Fire Impacts on the Mojave Desert Ecosystem: Literature Review  

SciTech Connect (OSTI)

The Nevada National Security Site (NNSS) is located within the Mojave Desert, which is the driest region in North America. Precipitation on the NNSS varies from an annual average of 130 millimeters (mm; 5.1 inches) with a minimum of 47 mm (1.9 inches) and maximum of 328 mm (12.9 inches) over the past 15 year period to an annual average of 205 mm (8.1 inches) with an annual minimum of 89 mm (3.5 inches) and maximum of 391 mm (15.4 inches) for the same time period; for a Frenchman Flat location at 970 meters (m; 3182 feet) and a Pahute Mesa location at 1986 m (6516 feet), respectively. The combination of aridity and temperature extremes has resulted in sparsely vegetated basins (desert shrub plant communities) to moderately vegetated mountains (mixed coniferous forest plant communities); both plant density and precipitation increase with increasing elevation. Whereas some plant communities have evolved under fire regimes and are dependent upon fire for seed germination, plant communities within the Mojave Desert are not dependent on a fire regime and therefore are highly impacted by fire (Brown and Minnich, 1986; Brooks, 1999). As noted by Johansen (2003) natural range fires are not prevalent in the Mojave and Sonoran Deserts because there is not enough vegetation present (too many shrub interspaces) to sustain a fire. Fire research and hence publications addressing fires in the Southwestern United States (U.S.) have therefore focused on forest, shrub-steppe and grassland fires caused by both natural and anthropogenic ignition sources. In the last few decades, however, invasion of mid-elevation shrublands by non-native Bromus madritensis ssp. rubens and Bromus tectorum (Hunter, 1991) have been highly correlated with increased fire frequency (Brooks and Berry, 2006; Brooks and Matchett, 2006). Coupled with the impact of climate change, which has already been shown to be playing a role in increased forest fires (Westerling et al., 2006), it is likely that the fire frequency will further increase in the Mojave Desert (Knapp 1998; Smith et al., 1987; Smith et al., 2000).

Improved high temperature solar absorbers for use in Concentrating Solar Power central receiver applications.  

SciTech Connect (OSTI)

Concentrating solar power (CSP) systems use solar absorbers to convert the heat from sunlight to electric power. Increased operating temperatures are necessary to lower the cost of solar-generated electricity by improving efficiencies and reducing thermal energy storage costs. Durable new materials are needed to cope with operating temperatures >600 C. The current coating technology (Pyromark High Temperature paint) has a solar absorptance in excess of 0.95 but a thermal emittance greater than 0.8, which results in large thermal losses at high temperatures. In addition, because solar receivers operate in air, these coatings have long term stability issues that add to the operating costs of CSP facilities. Ideal absorbers must have high solar absorptance (>0.95) and low thermal emittance (<0.05) in the IR region, be stable in air, and be low-cost and readily manufacturable. We propose to utilize solution-based synthesis techniques to prepare intrinsic absorbers for use in central receiver applications.

Concentrated solar energy applications using Fresnel lenses: A review  

Science Journals Connector (OSTI)

Solar energy concentration technology using Fresnel lens is an effective way to make full use of sunlight. This paper makes a review about the recent development of the concentrated solar energy applications using Fresnel lenses. The ongoing research and development involves imaging systems and non-imaging systems. Compared with imaging systems, non-imaging systems have the merits of larger accept angles, higher concentration ratios with less volume and shorter focal length, higher optical efficiency, etc. Concentrated photovoltaics is a major application and the highest solar-to-electric conversion efficiency based on imaging Fresnel lens and non-imaging Fresnel lens are reported as over 30% and 31.51.7%, respectively. Moreover, both kinds of systems are widely used in other fields such as hydrogen generation, photo-bio reactors as well as photochemical reactions, surface modification of metallic materials, solar lighting and solar-pumped laser. During the recent two decades, such applications have been built and tested successfully to validate the practicality of Fresnel lens solar concentration systems. Although the present application scale is small, the ongoing research and development works suggest that Fresnel lens solar concentrators, especially non-imaging Fresnel lenses, will bring a breakthrough of commercial solar energy concentration application technology in the near future. Finally, the advantages and disadvantages of two systems are also summarized.

launches unique research initiative to realize solar energy's launches unique research initiative to realize solar energy's full potential By Angela Hardin * February 22, 2010 Tweet EmailPrint Spurred by global development and population growth, the world's energy needs are expected to double by 2050. The best solution to meet this coming demand is an energy mix that includes generous amounts of renewable energy sources such as solar, wind and biofuels, as well as nuclear energy and fossil fuels. Of the many options, the sun represents the most abundant renewable energy source. Its rays have a potential supply that dwarfs the global demand for energy today and for the foreseeable future. However, the costs of converting sunlight to usable electricity, heat or fuel must be radically reduced to realize this potential. And that can only be accomplished

7 6/1/2011 7 6/1/2011 2.20 Making Solar Energy More Affordable The cost of solar electricity has been reduced 100-fold over the past two decades, but further reductions are needed before solar power is widely used. Scientists at the National Renewable Energy Laboratory took major steps toward this goal by designing photovoltaic cells (which convert sunlight to electricity) with 30 percent efficiency, much higher than the 10-20 percent levels achieved previously. The new cells consist of thin layers of semiconductors applied to a low-cost backing, such as glass or plastic. The researchers received Office of Science support to develop a basic understanding of the opto- electronic properties of various semiconductors. Calculations of electronic structure provided the knowledge needed to

Doped surfaces in one sun, point-contact solar cells  

SciTech Connect (OSTI)

This letter reports two new types of large-area (>8.5 cm/sup 2/), backside, point-contact solar cells with doped surfaces, designed for use in unconcentrated sunlight. One type was fabricated on an intrinsic substrate with an optimized phosphorus diffusion on the sunward surface. The apertured-area efficiency was independently measured to be 22.3% at 1 sun (0.100 W/cm/sup 2/), 25 /sup 0/C, the highest reported for a silicon solar cell. The other type is constructed on a doped substrate, and has an apertured-area efficiency of 20.9%, the highest reported for a point-contact solar cell with a base in low-level injection. Both cells have record open-circuit voltages above 700 mV.

Building design guidelines for solar energy technologies  

SciTech Connect (OSTI)

There are two main objectives to this publication. The first is to find out the communalities in the experience gained in previous studies and in actual applications of solar technologies in buildings, residential as well as nonresidential. The second objective is to review innovative concepts and products which may have an impact on future developments and applications of solar technologies in buildings. The available information and common lessons were collated and presented in a form which, hopefully, is useful for architects and solar engineers, as well as for teachers of solar architecture'' and students in Architectural Schools. The publication is based mainly on the collection and analysis of relevant information. The information included previous studies in which the performance of solar buildings was evaluated, as well as the personal experience of the Author and the research consultants. The state of the art, as indicated by these studies and personal experience, was summarized and has served as basis for the development of the Design Guidelines. In addition to the summary of the state of the art, as was already applied in solar buildings, an account was given of innovative concepts and products. Such innovations have occurred in the areas of thermal storage by Phase Change Materials (PCM) and in glazing with specialized or changeable properties. Interesting concepts were also developed for light transfer, which may enable to transfer sunlight to the core areas of large multi story nonresidential buildings. These innovations may have a significant impact on future developments of solar technologies and their applications in buildings. 15 refs., 19 figs., 3 tabs.

Solar/heat?driven thermoacoustic engine  

Science Journals Connector (OSTI)

With its abundance and cleanliness solar energy has been harnessed to generate power using various techniques. A thermoacoustic engine is described which was built instrumented and tested to demonstrate use of solar power to generate acoustic power. Sunlight is collected using a 3?ft?diam acrylic Fresnel lens and focused on one end of a ceramic stack. This engine has a total length of 40 cm and resonates at around 420 Hz. To permit testing on the abundant cloudy days in Pennsylvania an electrical heater was also built and installed to provide a reliable thermal energy source for indoor measurements. Experimental results are in reasonable agreement with a DE L T AE model. When running in solar mode as a 1/4 wavelength open end resonator the measured acoustic SPL can reach 120 dB easily at 1 m away from the open end on a clear day. The onset of sound generation can be achieved even with a 1?ft?diam Fresnel lens. While an impressive demonstration in terms of sound output despite modest efficiency real solar energy conversion will be improved with inert gas mixtures at higher pressures.

Concentrating Solar Power: Best Practices Handbook for the Collection and Use of Solar Resource Data (CSP)  

SciTech Connect (OSTI)

As the world looks for low-carbon sources of energy, solar power stands out as the most abundant energy resource. Harnessing this energy is the challenge for this century. Photovoltaics and concentrating solar power (CSP) are two primary forms of electricity generation using sunlight. These use different technologies, collect different fractions of the solar resource, and have different siting and production capabilities. Although PV systems are most often deployed as distributed generation sources, CSP systems favor large, centrally located systems. Accordingly, large CSP systems require a substantial investment, sometimes exceeding $1 billion in construction costs. Before such a project is undertaken, the best possible information about the quality and reliability of the fuel source must be made available. That is, project developers need to have reliable data about the solar resource available at specific locations to predict the daily and annual performance of a proposed CSP plant. Without these data, no financial analysis is possible. This handbook presents detailed information about solar resource data and the resulting data products needed for each stage of the project.

A key review on present status and future directions of solar energy studies and applications in Saudi Arabia  

Science Journals Connector (OSTI)

Renewable energy is accepted as a key source for the future, not only for Saudi Arabia, but also for the world. Saudi Arabia has abundant potential for exploiting solar energy, which is renewable, clean, and freely available. The average annual solar radiation falling on the Arabian Peninsula is about 2200kWh/m2. Applications of solar energy in Saudi Arabia have been growing since 1960. Solar hydrogen production plant situated at the Solar Village, Riyadh, Saudi Arabia, could have been considered as the world's first 350kW solar-powered hydrogen-generation plant at the time of its inception. The development of solar energy, however, has been relatively low due to several obstacles although utilization of solar energy in its various aspects is very attractive for the country. The main objectives of this study are to address current applications and future aspects of solar energy along with studies conducted in this field and to assess them in the light of available sustainable energy technologies towards establishing energy policies. The solar energy-related topics reviewed include various types of solar radiation correlations, exergetic solar radiation, solar collectors, solar photovoltaic (PV) systems, solar stills, solar-powered irrigation, solar energy-related greenhouses, solar hydrogen, solar water desalination and solar energy education. Some barriers, scenarios and constraints are also covered. The utilization of solar energy could cover a significant part of the energy demand in the country. If a major breakthrough is achieved in the field of solar-energy conversion, Saudi Arabia can be a leading producer and exporter of solar energy in the form of electricity. The geographical location of the country, its widespread unused desert land, and year-round clear skies, all make it an excellent candidate for this.

CO2 EFFECTS ON MOJAVE DESERT PLANT INTERACTIONS  

SciTech Connect (OSTI)

Seasonal and interannual droughts characteristic of deserts have the potential to modify plant interactions as atmospheric CO{sub 2} concentrations continue to rise. At the Nevada Desert FACE (free-air CO{sub 2} enrichment) facility in the northern Mojave Desert, the effects of elevated atmospheric C02 (550 vs. ambient {approx}360 {micro}mol mol{sup -1}) on plant interactions were examined during two years of high and low rainfall. Results suggest that CO{sub 2} effects on the interaction between native species and their understory herbs are dependent on the strength of competition when rainfall is plentiful, but are unimportant during annual drought. Seasonal rainfall for 1999 was 23% the long-term average for the area, and neither elevated CO{sub 2} nor the low production of herbaceous neighbors had an effect on relative growth rate (RGR, d{sup -1}) and reproductive effort (RE, number of flowers g{sup -1}) for Achnatherum hymenoides (early season perennial C{sub 3} grass), Pleuraphis rigida (late season perennial C{sub 4} grass), and Larrea tridentata (evergreen C{sub 3} shrub). In contrast, 1998 received 213% the average rainfall. Consequently, the decrease in RGR and increase in RE for Achnatherum, whose period of growth overlaps directly with that of its neighbors, was exaggerated at elevated CO{sub 2}. However, competitive effects of neighbors on Eriogonum trichopes (a winter annual growing in shrub interspaces), Pleuraphis and Larrea were not affected by elevated CO{sub 2}, and possible explanations are discussed. Contrary to expectations, the invasive annual neighbor Bromus madritensis ssp. rubens had little influence on target plant responses because densities in 1998 and 1999 at this site were well below those found in other studies where it has negatively affected perennial plant growth. The extent that elevated CO{sub 2} reduces the performance of Achnatherum in successive years to cause its loss from the plant community depends more on future pressure from herbaceous neighbors and less on the extent that CO{sub 2} enhances Achnatherum growth during periods of severe drought.

Invents a Superior Diagnostics Invents a Superior Diagnostics Tool for Solar Cell Manufacturing A solid-state optical system, invented by the National Renewable Energy Laboratory (NREL) and commercialized by Tau Science, measures solar cell quantum efficiency (QE) in less than a second, enabling a suite of new capabilities for solar cell manufacturers. QE measurements indicate how well a solar cell converts the various wavelengths of sunlight into electricity. To ensure quality and optimize solar cell efficiency, solar cell manufacturers want to measure the QE of every cell they produce. When a cell does not perform in a certain wavelength range, that tells manufacturers to adjust their production tools to fix the problem. So measuring QE is a crucial diagnostic tool for solar cell performance.

Device physics and characterization of silicon point-contact solar cells  

SciTech Connect (OSTI)

The silicon point-contact solar cell is a candidate solar cell for use in highly concentrated sunlight. Recent progress is described for a point-contact solar cell optimized for incident power densities of 36 Watts/cm/sup 2/. The design and fabrication for several device runs is discussed in detail. Extensive data from these solar cells is presented in order to display the major trends in device design and performance. The data culminate in a solar cell that is 28% efficient for incident power densities between 4 and 15 watts/cm/sup 2/ at 25/sup 0/C. Utilizing measurements from several runs of solar cells, a three-dimensional model is compared to the data in order to establish a strong baseline case from which future design enhancements can be evaluated. A modeling study of the optimum geometries for point-contact solar cells provides the context for a discussion of the device physics of the solar-cell operation. These studies indicate that efficiencies exceeding 30% may soon be attained. The ultimate efficiency of silicon solar cells will be limited parasitic Auger recombination. With the model, a device is optimized to measure the carrier lifetimes in highly-injected silicon in the carrier density range of interest for solar cell operation, 1 X 10/sup 15/ to 2 x 10/sup 17/ carriers/cm/sup 2/.

Plasmonic effect of gold nanoparticles in organic solar cells  

Science Journals Connector (OSTI)

Abstract Light trapping, due to the embedding of metallic nanoparticles, has been shown to be beneficial for a better photoabsorption in organic solar cells. Researchers in plasmonics and in the organic photovoltaics fields are working together to improve the absorption of sunlight and the photonelectron coupling to boost the performance of the devices. Recent advances in the field of plasmonics for organic solar cells focus on the incorporation of gold nanoparticles. This article reviews the different methods to produce and embed gold nanoparticles into organic solar cells. In particular, concentration, size and geometry of gold nanoparticles are key factors that directly influence the light absorption in the devices. It is shown that a careful choice of size, concentration and location of gold nanoparticles in the device result in an enhancement of the power conversion efficiencies when compared to standard organic solar cell devices. Our latest results on gold nanoparticles embedded in on organic solar cell devices are included. We demonstrate that embedded gold nanoparticles, created by depositing and annealing a gold film on transparent electrode, generate a plasmonic effect which can be exploited to increase the power conversion efficiency of a bulk heterojunction solar cell up to 10%.

Conversion of Solar to Electrical Energy  

Science Journals Connector (OSTI)

A photovoltaic device has been developed which converts solar radiation directly into electrical energy with an over-all efficiency of 11%. This consists of a p-n junction formed by gaseous diffusion near the front surface of a silicon plate. In full sunlight a single cell furnishes approximately 30 ma of short circuit current per square centimeter of surface 0.6 v of open circuit voltage and 12 mw of power into a matched load per square centimeter of surface. Like other electric batteries individual cells may be connected in series or parallel to obtain an increase in terminal voltage or current. The spectral response is a maximum near 0.7 and the long wavelength cutoff is at approximately 1.1 . The efficiency of this new siliconp-n junctionphotovoltaic cell is greater by a factor of 20 than that previously reported for other types of photocells and makes the conversion of the sun's energy directly into electricity possible for a number of interesting applications. A Bell System field trial at Americus Georgia in which solar batteries are used to power a rural carrier telephone communication system is described. A number of other possible applications for this new solar energy converter are discussed.

Solar Cookers to Bring Hope to Earthquake Victims | Department of Energy

Solar Cookers to Bring Hope to Earthquake Victims Solar Cookers to Bring Hope to Earthquake Victims Solar Cookers to Bring Hope to Earthquake Victims March 8, 2010 - 11:00am Addthis How does it work? The type of cooker distributed by Solar Cookers International consists of two parts: a heat-resistant plastic bag placed around a dark-colored cooking pot. When sunlight passes through the bag and hits the pot, it's converted into heat energy. The heat energy can't get out of the plastic bag as easily as the light got in, which traps the heat inside. This allows cookers to reach temperatures around 250 degrees Fahrenheit, high enough to boil water. January's devastating earthquake made Haiti's previous power infrastructure problems even worse. According to the World Bank, Haitians meet about 70 percent of their power needs by burning firewood or charcoal.

Electrostatic cleaning system for removal of sand from solar panels  

Science Journals Connector (OSTI)

Abstract An improved cleaning system has been developed that uses electrostatic force to remove sand from the surface of solar panels. A single-phase high voltage is applied to parallel wire electrodes embedded in the cover glass plate of a solar panel. It has been demonstrated that more than 90% of the adhering sand is repelled from the surface of the slightly inclined panel after the cleaning operation. The performance of the system was further improved by improving the electrode configuration and introducing natural wind on the surface of the panel, even when the deposition of sand on the panel is extremely high. The power consumption of this system is virtually zero. This technology is expected to increase the effective efficiency of mega solar power plants constructed in deserts at low latitudes.

Solar collector  

SciTech Connect (OSTI)

A solar collector is disclosed which is tiltable about a horizontal axis so as to vary the angle at which solar radiation is received by the collector. The solar collector, which uses air as the heat transfer medium, has connected to it a pair of fixed, well-insulated air transfer passages which penetrate through into the interior of the collector at the lateral sides thereof aligned with the horizontal axis about which the collector is pivoted. The air transfer passages are insulated and are gasketed to the sides of the collector so as to improve the efficiency of the solar energy system by avoiding losses of heat from the heat transfer fluid during transfer of the fluid from the collector to the space being heated.

Novel integration options of concentrating solar thermal technology with fossil-fuelled and CO2 capture processes  

Science Journals Connector (OSTI)

Concentrating solar thermal (CST) technology has been commercially proven in utility-scale power plants that have been in operation since the 1980s. CST uses reflecting surfaces to focus solar energy onto collectors, generating extreme heat than can be used for a variety of purposes. The current focus of CST is large-scale electrical power generation. However, new applications, such as solar fuels, are quickly gaining momentum. One key shortcoming of CST technology is its sensitivity to disruptions in sunlight availability over time. CST systems require either thermal energy storage or backup systems to operate during heavy cloud periods or at night. On the other hand, fossil-based energy systems have high availability and reliability, but they generate substantial CO2 emissions compared to equivalent CST processes. A novel solution would combine the benefits of CST technology and of fossil-fueled energy systems. Such a solar-fossil hybrid system would guarantee energy availability in the absence of sunlight or stored solar energy. The addition of carbon capture to these systems could reduce their carbon intensity to almost zero. This paper introduces three important solar-fossil hybrid energy systems: (1) Integrated Solar Combined Cycle (ISCC), (2) Solar-assisted post-combustion capture (SAPCAP), and (3) Solar gasification with CO2 capture. These novel concepts have great potential to overcome the inherent limitations of their component technologies and to achieve superior greenhouse gas mitigation techno-economic performance in large-scale applications. The paper describes the features of the three solar-fossil hybrid systems described earlier, discusses its advantages and disadvantages, and provides examples of applications. The goal of this manuscript is to introduce experts in the CCS and CST fields to the opportunities of integration between these technologies and their potential benefits.

Solar powered heat pump construction. [silica gel adsorbent with solar regenerator  

SciTech Connect (OSTI)

Disclosed is a solar powered heat pump useful for both heating and cooling building space and for providing refrigeration. The device operates on a chemical effect (Adsorption) intermittent heat pump cycle in which the moderately high temperature heat generated by insolation is used to drive the desorber. The device has inherent thermal storage, can be factory built, sealed, and tested, can be electronically controlled for completely automatic operation, and includes a built-in back-up heater which obviates the need for installation of a separate back-up heating system. It can be manufactured from inexpensive materials such as glass, and implodes rather than explodes on failure. A preferred embodiment of the device is designed as a modular unit which can readily be combined with others of identical design to produce a solar powered battery panel for heating and cooling. This embodiment preferably comprises a tubular enclosure defining a pair of chambers separated by a valve. A first chamber is packed with silica gel (Or an equivalent adsorbent material) arranged such that mass and heat transfer through the gel take place rapidly and in comparable time periods. The first chamber is surrounded by a larger diameter, solar radiation transparent housing and the annular space between the chamber and housing is evacuated. The enclosure is mounted together with a diffuse light reflector which focuses sunlight toward the first chamber. Heat exchangers provide thermal communication between respective chambers and a pair of duct portions adapted for connection to a building heat distribution system.

Solar Neutrinos  

DOE R&D Accomplishments [OSTI]

The prospect of studying the solar energy generation process directly by observing the solar neutrino radiation has been discussed for many years. The main difficulty with this approach is that the sun emits predominantly low energy neutrinos, and detectors for observing low fluxes of low energy neutrinos have not been developed. However, experimental techniques have been developed for observing neutrinos, and one can foresee that in the near future these techniques will be improved sufficiently in sensitivity to observe solar neutrinos. At the present several experiments are being designed and hopefully will be operating in the next year or so. We will discuss an experiment based upon a neutrino capture reaction that is the inverse of the electron-capture radioactive decay of argon-37. The method depends upon exposing a large volume of a chlorine compound, removing the radioactive argon-37 and observing the characteristic decay in a small low-level counter.

Solar heating for a commercial-sized swimming pool. Final report  

SciTech Connect (OSTI)

The task of the project was to build a solar heating system for a large community pool. Racks for the sixty collectors were constructed of redwood as described in the section on carpentry work. The plumbing section details the ease of putting together the collectors as well as the difficulty of hooking up the pipe to the pumps and inline filters. An automatic controller unit turns the pumps on and off depending on the availability of sunlight. After two years of work, the system is operable, but the pool cover purchased in the first year may be more effective than the entire solar heating system. Optimal solar efficiency may not be practical. The details of this finding are discussed in the section on conclusions, pitfalls, and recommendations.

Turning Bacteria into Fuel: Cyanobacteria Designed for Solar-Powered Highly Efficient Production of Biofuels  

SciTech Connect (OSTI)

Broad Funding Opportunity Announcement Project: ASU is engineering a type of photosynthetic bacteria that efficiently produce fatty acidsa fuel precursor for biofuels. This type of bacteria, called Synechocystis, is already good at converting solar energy and carbon dioxide (CO2) into a type of fatty acid called lauric acid. ASU has modified the organism so it continuously converts sunlight and CO2 into fatty acidsoverriding its natural tendency to use solar energy solely for cell growth and maximizing the solar-to-fuel conversion process. ASUs approach is different because most biofuels research focuses on increasing cellular biomass and not on excreting fatty acids. The project has also identified a unique way to convert the harvested lauric acid into a fuel that can be easily blended with existing transportation fuels.

Solar project description for Gill Harrop, Builders, single-family detached residence, Big Flats, New York  

SciTech Connect (OSTI)

The Gill Harrop Builders Site is a house with approximately 1360 square feet of conditioned space heated by a direct gain system with manually operated insulated curtains. Solar heating is augmented by electric resistance heating, and a wood burning stove may be installed. Sunlight is admitted through both south facing windows and through clerestory collector panels and is absorbed and stored as heat in a concrete floor and wall. Heat is then distributed by natural convection and radiation. Temperature regulation is assisted by earth berms. Three modes of operation are described: collector-to-storage, storage-to-space heating, and passive space cooling, which is accomplished by shading, movable insulation, and ventilation. The instrumentation for the National Solar Data Network is described. The solar energy portion of the construction costs is estimated to be $7000. (LEW)

Pre-treating Seed to Enhance Germination of Desert Shrubs  

SciTech Connect (OSTI)

Creosotebush [Larrea tridentata (D.C.) Cav.] and white bursage [Ambrosia dumosa (A. Gray) W.W. Payne] seeds were subjected to pre-treatments of rinsing and soaking in water and thiourea to enhance germination in laboratory experiments. The effects of darkness, temperature, seed source, and soil moisture were also evaluated in the laboratory. The best pre-treatment from the laboratory experiments, rinsing with water for 36 hours followed by drying, was field-tested at Fort Irwin, California. Two sites and two seeding dates (early March and mid April) were determined for each site. Five mulch treatments (no mulch, straw, gravel, chemical stabilizer, and plastic) were evaluated in combination with the seed pre-treatments. Field emergence was greatly enhanced with the seed pre-treatment for white bursage during the March (18-42% increase in germination) and April seedings (16-23% increase in germination). Creosotebush showed poor germination during March (2-5%) when soil temperatures averaged 15 C, but germination increased during the April trials (6-43%) when soil temperatures averaged 23 C. The seed pre-treatment during the April trials increased germination from 16-23%. The plastic mulch treatment increased germination dramatically during both the March and April trials. The plastic mulch increased soil temperatures (8-10 C)and maintained high humidity during germination. Both the chemical stabilizer and the gravel mulches improved germination over the control while the straw mulch decreased germination. These results suggest that seed pre-treatments combined with irrigation and mulch are effective techniques to establish these two dominant Mojave Desert species from seed.

Reducing the Cost of Energy from Parabolic Trough Solar Power Plants: Preprint  

SciTech Connect (OSTI)

Parabolic trough solar technology is the most proven and lowest cost large-scale solar power technology available today, primarily because of the nine large commercial-scale solar power plants that are operating in the California Mojave Desert. However, no new plants have been built during the past ten years because the cost of power from these plants is more expensive than power from conventional fossil fuel power plants. This paper reviews the current cost of energy and the potential for reducing the cost of energy from parabolic trough solar power plant technology based on the latest technological advancements and projected improvements from industry and sponsored R&D. The paper also looks at the impact of project financing and incentives on the cost of energy.

Impact of the reaction conditions on the photocatalytic reduction of water on mesoporous polymeric carbon nitride under sunlight irradiation  

Science Journals Connector (OSTI)

Abstract Sacrificial hydrogen evolution was studied with solgel prepared carbon nitride photocatalysts loaded in-situ with platinum in a photocatalytic setup with defined geometry and a solar simulator as light source. Reaction conditions (e.g. photocatalyst concentration, triethanolamine concentration, amount of Pt precursor, water quality, etc.), and catalyst properties (e.g. BET surface area) were varied to optimize the catalysts for hydrogen evolution. We found that most of the parameters strongly influence the in-situ co-catalyst loading. The optimum platinum loading is between 0.03 and 0.09wt%, which is less than 5% of the initial amount of platinum. A long term stability test was conducted showing a stable hydrogen evolution rate for more than 10 days indicating a stable catalyst under applied reaction conditions. We found that a change in the BET surface area affects the photocatalytic activity rather than the experimental conditions.

Solar passive ceiling system. Final report. [Passive solar heating system with venetian blind reflectors and latent heat storage in ceiling  

SciTech Connect (OSTI)

The construction of a 1200 square foot building, with full basement, built to be used as a branch library in a rural area is described. The primary heating source is a passive solar system consisting of a south facing window system. The system consists of: a set of windows located in the south facing wall only, composed of double glazed units; a set of reflectors mounted in each window which reflects sunlight up to the ceiling (the reflectors are similar to venetian blinds); a storage area in the ceiling which absorbs the heat from the reflected sunlight and stores it in foil salt pouches laid in the ceiling; and an automated curtain which automatically covers and uncovers the south facing window system. The system is totally passive and uses no blowers, pumps or other active types of heat distribution equipment. The building contains a basement which is normally not heated, and the north facing wall is bermed four feet high around the north side.

Solar Neutrinos  

E-Print Network [OSTI]

Experimental work with solar neutrinos has illuminated the properties of neutrinos and tested models of how the sun produces its energy. Three experiments continue to take data, and at least seven are in various stages of planning or construction. In this review, the current experimental status is summarized, and future directions explored with a focus on the effects of a non-zero theta-13 and the interesting possibility of directly testing the luminosity constraint. Such a confrontation at the few-percent level would provide a prediction of the solar irradiance tens of thousands of years in the future for comparison with the present-day irradiance. A model-independent analysis of existing low-energy data shows good agreement between the neutrino and electromagnetic luminosities at the +/- 20 % level.

Solar collector  

SciTech Connect (OSTI)

The disclosure is a solar collector consisting of glass rods enclosed in a housing and mounted vertically on a roof or other elevated place to gather solar rays. The collector is fixed, with no tracking device or other moving parts. The glass rods are 6 mm or smaller in diameter, and there can be several thousand, depending on the sizes of the rods and collector. The upper ends of the rods are inclined at an angle of thirty degrees from horizontal, with the inclined surfaces occupying a plane which faces south so as to obtain maximum exposure to the winter sun. Solar rays striking the inclined ends of the rods are refracted into the rods. The rays travel down through the rods, with a predominantly parallel path of propagation being established by repeated reflections off the inside walls of the rods. The rays are emitted from the lower perpendicular ends of the rods as parallel rays of incoherent light which are directed into beam concentrators.

Abstract Jacobson et al. (2013, hereinafter J13), presented the technical and economic feasibility of converting New York States' all-purpose energy infrastructure (electricity, transportation, heating/cooling, industry) to one powered by wind, water, and sunlight (WWS) producing electricity and electrolytic hydrogen. Gilbraith et al. (2013) question several aspects of our approach. Unfortunately, Gilbraith et al. inaccurately portray what we stated and referenced and ignore many recent supporting studies. They also refer to previous misplaced critiques of our earlier global WWS study but fail to reference the responses to those critiques, Delucchi and Jacobson (2011b) and Jacobson and Delucchi (2013). We fully stand by the conclusions of both the previous and present studies.

Solar neutrinos and the solar composition problem  

E-Print Network [OSTI]

Standard solar models (SSM) are facing nowadays a new puzzle: the solar composition problem. New determinations of solar metal abundances lead SSM calculations to conflict with helioseismological measurements, showing discrepancies that extend from the convection zone to the solar core and can not be easily assigned to deficiencies in the modelling of the solar convection zone. We present updated solar neutrino fluxes and uncertainties for two SSM with high (old) and low (new) solar metallicity determinations. The uncertainties in iron and carbon abundances are the largest contribution to the uncertainties of the solar neutrino fluxes. The uncertainty on the ^14N+p -> ^15O+g rate is the largest of the non-composition uncertainties to the CNO neutrino fluxes. We propose an independent method to help identify which SSM is the correct one. Present neutrino data can not distinguish the solar neutrino predictions of both models but ongoing measurements can help to solve the puzzle.

Study of Desert Dust Events over the Southwestern Iberian Peninsula in Year 2000: Two Case Studies  

SciTech Connect (OSTI)

Strong desert dust events occurring in 2000 over the southwestern Atlantic coast of the Iberian Peninsula are detected and evaluated by means of the TOMS Aerosol Index (A.I.) at three different sites, Funchal (Madeira Island, Portugal), Lisboa (Portugal), and El Arenosillo (Huelva, Spain). At the El Arenosillo station, measurements from an AERONET Cimel sunphotometer allow more retrieval of the spectral AOD and the derived alpha ''angstrom'' coefficient. After using different threshold values of these parameters, we conclude that it is difficult to establish reliable and robust criteria for an automatic estimation of the number of dust episodes and the total number of dusty days per year. As a result, additional information, such as airmass trajectories, were used to improve the estimation, from which reasonable results were obtained (although some manual editing was still needed). A detailed characterization of two selected desert dust episodes, a strong event in winter and another of less intensity in summer, was carried out using AOD derived from Brewer spectrometer measurements. Size distribution parameters and radiative properties, such as refractive index and the aerosol single scattering albedo derived from Cimel data, were analyzed in detail for one of these two case studies. Although specific to this dust episode, the retrieved range of values of these parameters clearly reflect the characteristics of desert aerosols. Back-trajectory analysis, synoptic weather maps and satellite images were also considered together, as supporting data to assess the aerosol desert characterization in this region of study.

Technical and economical system comparison of photovoltaic and concentrating solar thermal power systems depending on annual global irradiation  

Science Journals Connector (OSTI)

Concentrating solar thermal power and photovoltaics are two major technologies for converting sunlight to electricity. Variations of the annual solar irradiation depending on the site influence their annual efficiency, specific output and electricity generation cost. Detailed technical and economical analyses performed with computer simulations point out differences of solar thermal parabolic trough power plants, non-tracked and two-axis-tracked PV systems. Therefore, 61 sites in Europe and North Africa covering a global annual irradiation range from 923 to 2438 kWh/m2a have been examined. Simulation results are usable irradiation by the systems, specific annual system output and levelled electricity cost. Cost assumptions are made for today's cost and expected cost in 10 years considering different progress ratios. This will lead to a cost reduction by 50% for PV systems and by 40% for solar thermal power plants. The simulation results show where are optimal regions for installing solar thermal trough and tracked PV systems in comparison to non-tracked PV. For low irradiation values the annual output of solar thermal systems is much lower than of PV systems. On the other hand, for high irradiations solar thermal systems provide the best-cost solution even when considering higher cost reduction factors for PV in the next decade. Electricity generation cost much below 10 Eurocents per kWh for solar thermal systems and about 12 Eurocents/kWh for PV can be expected in 10 years in North Africa.

Solar collector  

DOE Patents [OSTI]

The field of this invention is solar collectors, and more particularly, the invention pertains to a flat plate collector that employs high performance thin films. The solar collector of this invention overcomes several problems in this field, such as excessive hardware, cost and reliability, and other prior art drawbacks outlined in the specification. In the preferred form, the apparatus features a substantially rigid planar frame (14). A thin film window (42) is bonded to one planar side of the frame. An absorber (24) of laminate construction is comprised of two thin film layers (24a, 24b) that are sealed perimetrically. The layers (24a, 24b) define a fluid-tight planar envelope (24c) of large surface area to volume through which a heat transfer fluid flows. Absorber (24) is bonded to the other planar side of the frame. The thin film construction of the absorber assures substantially full envelope wetting and thus good efficiency. The window and absorber films stress the frame adding to the overall strength of the collector.

Solar skylight  

DOE Patents [OSTI]

A reflective shutter rotates within a skylight housing in such a fashion as to control solar energy thereby providing a combination of heating, lighting, and ventilation. The skylight housing has three faces: a glazed southern face, a glazed northern face, and an open downwardly oriented face to the interior of the structure. Counter-weighted pivot arms support the shutter at either end causing the center of rotation to pass through the center of gravity. The shutter has three basic positions: In the first position, during the winter day, the shutter closes off the northern face, allowing solar energy to enter directly into the supporting structure providing heat gain and daylighting. In the second position, during the winter night, the shutter closes off the open face to the interior, providing insulation between the structure and the skylight housing. In the third position, during the non-heating season, the shutter closes off the southern face blocking unwanted heat gain but allowing diffuse northern light to penetrate for daylighting. In this last position, a means is provided for ventilating by natural convection. The apparatus can be operated either manually or by motor.

Award-Winning Etching Process Award-Winning Etching Process Cuts Solar Cell Costs In general, when it comes to photovoltaic (PV) solar cells, the higher their efficiency, the higher their price tag. To increase cell efficiencies while lowering costs, scientists at the National Renewable Energy Laboratory (NREL) invented the "black silicon" nanocatalytic wet-chemical etch. This inexpensive, one-step method enables the creation of high-efficiency crystalline silicon solar cells based on an innovative antireflection approach that promises to significantly reduce manufacturing costs. Most of today's solar cells are made from silicon, and NREL's simple antireflection etch turns silicon wafers black, allowing them to absorb more than 98% of incident sunlight. NREL's new process, a one-step immersion in a chemical bath, creates a highly antireflective

Parabolic trough solar power for competitive U.S. markets  

SciTech Connect (OSTI)

Nine parabolic trough power plants located in the California Mojave Desert represent the only commercial development of large-scale solar power plants to date. Although all nine plants continue to operate today, no new solar power plants have been completed since 190. Over the last several years, the parabolic trough industry has focused much of its efforts on international market opportunities. Although the power market in developing countries appears to offer a number of opportunities for parabolic trough technologies due to high growth and the availability of special financial incentives for renewables, these markets are also plagued with many difficulties for developers. In recent years, there has been some renewed interest in the U.S. domestic power market as a results of an emerging green market and green pricing incentives. Unfortunately, many of these market opportunities and incentives focus on smaller, more modular technologies (such as photovoltaics or wind power), and as a result they tend to exclude or are of minimum long-term benefit to large-scale concentrating solar power technologies. This paper looks at what is necessary for large-scale parabolic trough solar power plants to compete with state-of-the-art fossil power technology in a competitive US power market.

Instead, using a combination of x-ray scattering and microscopy techniques, researchers have found that excitons may actually not fare so well in mixed domains but need access to pure aggregates to efficiently convert into charges.

The type of cooker distributed by Solar Cookers International consists of two parts: a heat-resistant plastic bag placed around a dark-colored cooking pot. When sunlight passes through the bag and hits the pot, it's converted into heat energy. The heat energy can't get out of the plastic bag as easily as the light got in, which traps the heat inside. This allows cookers to reach temperatures around 250 degrees Fahrenheit, high enough to boil water. January's devastating earthquake made Haiti's previous power infrastructure problems even worse. According to the World Bank, Haitians meet about 70 percent of their power needs by burning firewood or charcoal.

Quantum Dots Promise to Significantly Boost Solar Cell Efficiencies (Fact Sheet)  

SciTech Connect (OSTI)

In the search for a third generation of solar-cell technologies, a leading candidate is the use of 'quantum dots' -- tiny spheres of semiconductor material measuring only about 2-10 billionths of a meter in diameter. Quantum dots have the potential to dramatically increase the efficiency of converting sunlight into energy -- perhaps even doubling it in some devices -- because of their ability to generate more than one bound electron-hole pair, or exciton, per incoming photon. NREL has produced quantum dots using colloidal suspensions; then, using molecular self-assembly, they have been fabricated into the first-ever quantum-dot solar cells. While these devices operate with only 4.4% efficiency, they demonstrate the capability for low-cost manufacturing.
