This book was released on 2015-07-02 with total page 230 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present dissertation focuses on the development and characterization of industrially feasible, silicon-based low concentrator solar cells that can be manufactured on existing production lines. Both, theoretical and experimental approaches are introduced and discussed. Novel solar cell architectures such as metal-wrap-through as well as conventional designs are presented and specific advantages emphasized. The theoretical work is based on the extension of known expressions for the series resistance and its impact on the open-circuit-voltage. An experimental approach is introduced to extract the local recombination of the metal contacted emitter region. Furthermore, it is shown that the influence of the boron-oxygen complex, known to degrade p-type silicon is reduced for the concentrator application. The work concludes with the introduction of a novel unit cell design based on the metal-wrap-through architecture.

This book was released on 1996 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report presents a summary of the major results from a program to develop a manufacturable, high-efficiency silicon concentrator solar cell and a cost-effective manufacturing facility. The program was jointly funded by the Electric Power Research Institute, Sandia National Laboratories through the Concentrator Initiative, and SunPower Corporation. The key achievements of the program include the demonstration of 26%-efficient silicon concentrator solar cells with design-point (20 W/cm2) efficiencies over 25%. High-performance front-surface passivations; that were developed to achieve this result were verified to be absolutely stable against degradation by 475 days of field exposure at twice the design concentration. SunPower demonstrated pilot production of more than 1500 of these cells. This cell technology was also applied to pilot production to supply 7000 17.7-cm2 one-sun cells (3500 yielded wafers) that demonstrated exceptional quality control. The average efficiency of 21.3% for these cells approaches the peak efficiency ever demonstrated for a single small laboratory cell within 2% (absolute). Extensive cost models were developed through this program and calibrated by the pilot-production project. The production levels achieved indicate that SunPower could produce 7-10 MW of concentrator cells per year in the current facility based upon the cell performance demonstrated during the program.

This book was released on 1994 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the final report of a program to develop a commercial, high-efficiency, low-cost concentrator solar cell compatible with Spectrolab's existing manufacturing infrastructure for space solar cells. The period covered is between 1991 and 1993. The program was funded through Sandia National Laboratories through the DOE concentrator initiative and, was also cost shared by Spectrolab. As a result of this program, Spectrolab implemented solar cells achieving an efficiency of over 19% at 200 to 300X concentration. The cells are compatible with DOE guidelines for a cell price necessary to achieve a cost of electricity of 12 cents a kilowatthour.

Book excerpt: Research directed at improving the energy conversion efficiency of silicon concentrator solar cells over the year ending October 1987is described. The most promising approach identified for fabricating high -efficiency, bifacially contacted cells is one whereby the effects of top metallization shading can be negated, such as by the use of prismatic covers. This approach is shown to be capable of producing 25% cell efficiency for relatively large -area cells for concentration in the 100-500 suns range. Increase beyond this efficiency figure is dependent upon improvements in rear surface passivation. Results reported include the first demonstration of 19% lens/cell efficiency with silicon, the demonstration of improved performance levels for bifacially contacted high -resistivity cells, and the demonstration of the feasibility of applying the laser -grooved approach to large -area, low-cost concentrator cells. The theory of sublinear effects in high -resistivity cells is developed and shown to accurately describe experimental results. Finally, a new light -trapping scheme based on tilted pyramids and slats is analysed and shown to perform better than any other scheme analysed to date.

Book excerpt: This report describes work conducted between December 1990 and May 1992 continuing research on silicon concentrator solar cells. The objectives of the work were to improve the performance of high-efficiency cells upon p-type substrates, to investigate the ultraviolet stability of such cells, to develop concentrator cells based on n-type substrates, and to transfer technology to appropriate commercial environments. Key results include the identification of contact resistance between boron-defused areas and rear aluminum as the source of anomalously large series resistance in both p- and n-type cells. A major achievement of the present project was the successful transfer of cell technology to both Applied Solar Energy Corporation and Solarex Corporation.
