Difficulties and their solutions found during the determination of parameters of impurities in thin GaInNAs solar cells, by means of spectroscopic capacitance measurements, are presented in this work. The parameters of impurities present in the GaInNAs pn junctions are determined by an iterative method, comparing experimental capacitance transients with calculated ones. The results disagree with the...
The first version of a solar cell simulator specifically designed for the analysis of multijunction solar cells is presented. The simulation program solves the Poisson and continuity equations by using a procedure optimized for multilayer structures. It includes the radiative interband, Shockley-Read-Hall and Auger recombination mechanisms, and computes the generation function of electron-hole pairs...
