Abstract: In this article, the study of CIGS solar cells is carried out by employing 1-dimensional numerical simulations using the simulator AFORS-HET. Here simulation of the conventional structure of Al/SLG/ZnO: Al/i-ZnO/ZnSnO/CIGS/Mo solar cell is done in which experimental values are used for the verification of the simulation. Also, a novel architecture is designed by incorporating the cuprous oxide (p-type Cu2O) layer as an electron blocking layer (EBL)at back-contact for the reduction of the minority carrier recombination loss. The parameters of the cell are optimized at different concentrations of doping and thickness to get better performance. The obtained efficiency of the proposed structure is raised by 9.62% in comparison to the experimental work.
