Abstract

Thin film solar cells based on Cu2ZnSnS4 (CZTS) absorbers are proposed with the structure glass/Mo/CZTS/buffer/ZnO. In this work we have simulated CZTS thin film solar cell using solar cell capacitance simulator (SCAPS). The influences of thickness of (CZTS) absorber, thickness of (CdS) buffer layer and Zinc oxide window Layer (ZnO) on the photovoltaic cell parameters are studied. It can be seen after reviewing the results, that for high conversion efficiency, the cell should have a thin buffer layer and a thick absorber layer. In addition, the effect of operating temperature on the cell performance shows that the efficiency will be strongly affected by the increased temperature.
