Description

In this study, a numerical simulation of a BaZrS3-based perovskite solar cell was performed using SCAP-1D. An attempt was made to optimize the performance of the solar cell configuration FTO/ZnO/BaZrS3/WSe2 by varying several parameters. The effect of the variation of the thicknesses of the hole transport layer (HTL), electron transport layer (ETL), absorber (perovskite) layer, acceptor dopant density (ADD) of the HTL and perovskite layer, donor dopant density (DDD) of the ETL, series and shunt resistances and operating temperatures on the overall performance of the perovskite solar cell were investigated. A PCE of 30.03%, FF of 90.02 %, Jsc of 25.19 mA/cm-2, and Voc of 1.3242 V were obtained after several cell optimizations. The PCE obtained exceeded the highest reported PCE for BaZrS3-based perovskite solar cell (8.547 %) by 71.5%. The results obtained indicate that BaZrS3 can contribute to the development of non-toxic, efficient perovskite solar cells.
