This research work presents a numerical simulation of CZTS based solar cell by using one dimensional solar cell simulation program called solar cell capacitance simulator (SCAPS). In this work, the influence of In2S3 buffer layer thickness and natural defect density on the performance and the J-V characteristics of CZTS based solar cells has been studied. The simulation results illustrate that the optimal In2S3 buffer layer thickness is 50 nm. We observed that the defect density is perfect from1015 to 1017 cm – 3. The optimal photovoltaic parameters have been achieved with an efficiency of 20.95 % with JSC ( 26.85 mA/cm2 and VOC ( 0.78 V.
