In this paper, first, a physical model for a CdZnS / CdTe thin film solar cell with a ZnTe electron reflection layer is proposed, and then a new cell with the structure Cd .Zn.S/Cd ZnS/CdTe proposed for better performance. In this study, the effect of the thickness of the Cd ZnS buffer layer and also, the effect of zn concentration in Cd ZnS buffer layer on cell performance, analyzed. The results of our study show that optimum Cd ZnS buffer layer thickness for Cd ZnS buffer layer is 70 nanometer and optimal Zn concentration in this layer is 90%. Finally, an optimized CdTe solar cell Cd.Zn.S/Cd. Zn.)S/CdTe with performance parameters Voc=0.956 v, J=25.46 mA⁄cm!, ff=75.26%, Ƞ=16.28% has been designed.
