Simulation and Improvement of the Efciency of the CFTS Solar Cell Using SCAPS-1D

Abstract

A simulation of the AZO/i-ZnO/CdS/CFTS solar cell was carried out using SCAPS software. The results were obtained(Voc ¼ 0.55 V, Jsc ¼ 6.2 mA/cm2, FF ¼ 39%, ɳ ¼ 1.35%). Simulation results were compared with experimental researchand we got convergence in the results (Voc ¼ 0.56 V, Jsc ¼ 6.5 mA/cm2, FF ¼ 37%, ɳ ¼ 1.37%). The simulated solar cell isimproved by increasing the doping concentration and thickness of the buffer and absorption layers. The efficiency of thesolar cell was improved to ɳ ¼ 4.29%, fill factor FF ¼ 52.92%, open circuit voltage Voc ¼ 0.74 V and short circuit currentJsc ¼ 10.8 mA/cm2.
