Compound semiconductor CZTSe is a popular absorber layer for thin film solar cells. Instead of single semiconductor buffer layer, a hybrid buffer layer is used with CZTSe absorber layer. To reduce further usage of toxic materials(CdS) and simultaneously to increase the solar cell efficiency, Ag doped buffer layer was proposed and a numerical studies were performed using SCAPS 1-D simulation programme. Also the thickness and the carrier density of the different layers in the solar cell were optimized to achieve the above goals. After the simulation process, the toxic materials usage was reduced by 62% and the efficiency was increased from 12.24% to 12.69%
