GaAsP Top Solar Cells for Increased Solar Conversion Efficiency
Abstract
The development of multijunction solar cells is the key to achieving large increases in solar power conversion efficiency over current state-of-the- art technology. In the optimal multijunction design, the top solar cell is the most critical since, by itself, it generates two-thirds of the total power generated by the solar cell stack. There are two viable technical approaches for the top solar cell for the mechanically-stacked tandem solar cell: GaAsP/GaP and AlGaAs/AlGaAs. Both top solar cell approaches have demonstrated good device properties. No other approach has made acceptable devices.
