Theoretical Study of Multiple Solar Cells System as a Function of Temperature

Abstract

A simulation model has been performed on materials as Ge, Si, GaAs, AlGaAs and the values of gaps E_gk of hypothetical materials, the calculation of the corresponding maximum efficiency was carried out for multigap solar cells systems coupled in splitting mode. The effects of an optical coupling by a dichroic mirror between independent solar cells, and solar cells coupled in series has been analysed. One particular result of our study is that the coupling by a dichroic mirror between an independent cell gives an interesting efficiency.
