An examination of the regional supply and demand balance for renewable electricity in the United States through 2015
by Lori Bird
(
)
2 editions published between 2009 and 2010 in English and held by 416 WorldCat member libraries worldwide This report examines the balance between the demand and supply of new renewable electricity in the United States on a regional basis through 2015. It expands on a 2007 NREL study (NREL/TP-670-42266) that assessed the supply and demand balance on a national basis. As with the earlier study, this analysis relies on estimates of renewable energy supplies compared to demand for renewable energy generation needed to meet existing state renewable portfolio standard (RPS) policies in 28 states, as well as demand by consumers who voluntarily purchase renewable energy. However, it does not address demand by utilities that may procure cost-effective renewables through an integrated resource planning process or otherwise

Economic development benefits from wind power in Nebraska a report for the Nebraska Energy Office
by Eric Lantz
(
)
4 editions published between 2008 and 2009 in English and held by 411 WorldCat member libraries worldwide This report focuses on the economic development impacts estimated from building and operating 7,800 MW of new wind power in Nebraska. This level of development is on the scale envisioned in the Department of Energy (DOE) report, "20% Wind Energy by 2030." A practical first step to building 7,800 MW of wind is completing 1,000 MW. Thus, we also include the estimated economic impacts to Nebraska from building 1,000 MW of wind power. Our primary analysis indicates that the development and construction of approximately 7,800 MW of wind energy in Nebraska by 2030 will support 20,600 to 36,500 annual full-time equivalents (AFTE). In addition, operating the full 7,800 MW of wind energy could support roughly 2,000 to 4,000 full-time workers throughout the operating life of the wind facilities (LFTE). Nebraska's economy is estimated to see an average annual boost in economic activity ranging from $140 million to $260 million solely from construction and development related activities between 2011 and 2030. An additional boost of $250 - $442 million annually is estimated from operating 7,800 MW of wind capacity
Linearity testing of photovoltaic cells preprint
(
)
3 editions published in 2006 in English and held by 404 WorldCat member libraries worldwide Photovoltaic devices are rated in terms of their peak power with respect to a specific spectrum, total irradiance, and temperature. To rate photovoltaic devices, a reference detector is required whose response is linear with total irradiance. This paper describes a procedure to determine the linearity of the short-circuit current (Isc) versus the total irradiance (Etot) by illuminating a reference cell with two lamps. A device is linear if the current measured with both lamps illuminating the cell is the same as the sum of the currents with each lamp illuminating the cell. The two-lamp method is insensitive to the light spectra or spatial nonuniformity changing with irradiance. The two-lamp method is rapid, easy to implement, and does not require operator intervention to change the irradiances. The presence of room light only limits the lowest irradiance that can be evaluated. Unlike other methods, the two-lamp method does not allow the current to be corrected for nonlinear effects
Profiling the built-in electrical potential in III-V multijunction solar cells
(
)
3 editions published in 2006 in English and held by 399 WorldCat member libraries worldwide We report on a direct measurement of the electrical potential on cross-sections of GaInP2/GaAs multiple-junction solar cells by using an ultrahigh-vacuum scanning Kelvin probe microscope (UHV-SKPM). The UHV-SKPM allows us to measure the potential without air molecules being adsorbed on the cross-sectional surface. Moreover, it uses a GaAs laser with photon energy of 1.4 eV for the atomic force microscope (AFM) operation. This eliminated the light-absorption-induced bottom-junction flattening and top-junction enhancement, which happened in our previous potential measurement using a 1.85-eV laser for the AFM operation. Combining scanning tunneling microscopy (STM) and SKPM measurements, we found that the potential height at steps of the GaAs substrate depends on the step direction, which is probably a direct result of unbalanced cations and anions at the steps

Analysis of biodiesel blend samples collected in the United States in 2008
by T. L Alleman
(
)
2 editions published in 2010 in English and held by 390 WorldCat member libraries worldwide The quality of B20 (20 vol% biodiesel, 80 vol% petroleum diesel fuel) in the United States was sampled in 2008. Thirty-two samples from retail locations and fleets using B20 were tested against the proposed D7467 B6-B20 specification, which took effect later in 2008. Sixty percent were ±2% (nominally) B20. Twenty-five percent failed the proposed minimum induction period stability of 6 hours; the overall average was 8.4 hours. All B20 samples met proposed specifications for acid value, cetane, and ash. Ion chromatography was used to determine free and total glycerin in B20 blends. Results showed that all the B100 used for blending met D6751 glycerin specifications. Samples were analyzed by multidimensional gas chromatography to determine the B100 feedstock; most was soy-derived; some was animal-derived. The average dissolved water in B20 samples was 130 ppm, 30% higher than the typical saturation level of diesel fuel. Particulate contamination in the B20 was below 20 mg/L in every case but one
On the effect of the film hydrogen content and deposition type on the grain nucleation and grain growth during crystallization of a-Si:H films
(
)
3 editions published in 2006 in English and held by 389 WorldCat member libraries worldwide We report the effect of the initial film hydrogen content (CH) on the crystallization kinetics, crystallite nucleation rate and grain growth rate when HWCVD and PECVD a-Si:H films are crystallized by annealing at 600°C. We compare the results for HWCVD films of different film CH, and also for HWCVD and PECVD a-Si:H films containing the same initial film CH. We also perform Raman measurements on fully crystallized HWCVD films to explore whether film disorder plays a role in the different XRD FWHMs when different amounts of film hydrogen are evolved
Investigation of Cd1-xMgxTe alloys for tandem solar cell applications
(
)
3 editions published in 2006 in English and held by 389 WorldCat member libraries worldwide Theoretical modeling of two-junction tandem solar cells shows that for optimal device performance, the bandgap of the top cell should be in the range of 1.6 to 1.8 eV. Cd1-xMgxTe (CMT) alloys have a lattice constant close to that of CdTe, and the addition of a small amount of Mg changes the bandgap considerably. In this paper, we present our work on developing CMT for solar cell applications

Characterization of 19.9%-efficient CIGS absorbers preprint
(
)
2 editions published in 2008 in English and held by 377 WorldCat member libraries worldwide We recently reported a new record total-area efficiency, 19.9%, for CuInGaSe2 (CIGS)-based thin-film solar cells. Current-voltage analysis indicates that improved performance in the record device is due to reduced recombination. The reduced recombination was achieved by terminating the processing with a Ga-poor (In-rich) layer, which has led to a number of devices exceeding the prior (19.5%) efficiency record. This paper documents the properties of the world-record-efficiency CIGS solar cell by a variety of characterization techniques, with an emphasis on identifying near-surface properties associated with the modified processing more
