An Efficient CZTS Solar Cell from Numerical Analysis

The Copper Zinc Tin Sulfide (CZTS) is considered as one of the promising semiconductor materials in Kesterite family for potential solar cells absorber material. This work focuses on the numerical model and simulation of efficient CZTS based thin-film solar cell. Popular thin-film solar cell simulator wxAMPS was used for simulation of (Al:ZnO/i-ZnO/CdS/CZTS/Mo)structured solar cell and the effects of different layer properties on cell performance parameters were analyzed. An optimized cell with 15.84% (%FF=72.86, Voc=0.78Volt and Jsc=27.98 mA/cm2) energy conversion efficiency has proposed. The temperature coefficient (TC) of 0.02%/°C had shown the higher stability of the proposed cell. All of the simulated results had encouraged towards fabrication of high performance thin-film CZTS solar cells.
