In this paper, a discussion is made of the design of silicon cells to be used in a six-junction tandem solar cell structure as part of the Very High Efficiency Solar Cell (VHESC) program. Minority carrier recombination at surfaces and in the volume, internal quantum efficiency, resistance losses, free carrier parasitic absorption, optical reflection, light trapping, and light absorption must be traded...
In order to improve the efficiency of Czocharalski - Si (Cz-Si) photovoltaic cells, we have studied the distribution losses from recombination in Cz-Si commercial standard cell (Isofoton S.A.) by means of I-V measurements under solar simulation illumination with a surface irradiance of 1000 W/m2 and a light spectrum corresponding to a relative air mass of 1.5 G and the PC-ID software. The quantum...
