High Efficiency GaAs-GaAlAs Solar Cells for Very High Concentration Systems

摘要

Basic data on design and processing of GaAs-GaAlAs solar cells for high concentration ratios are briefly reported. Conversion efficiencies up to 23% at 100 suns and 17% at 925 suns have been measured. The temperature variation of conversion efficiency was also checked up to 200 exp 0 C and a close correlation between theoretical and experimental results was generally found. (ERA citation 05:017486)
