Abstract

We model the performance of two-junction solar cells at very high temperatures up to ~400 degrees C for applications such as hybrid PV/solar-thermal power production. We show that high-temperature operation reduces the sensitivity of the cell efficiency to spectral content, but increases the sensitivity to concentration, both of which have implications for energy yield in terrestrial PV applications. For other high-temperature applications such as near-sun space missions, our findings indicate that concentration may be a useful tool to enhance cell efficiency.
