ABSTRACT: This study presents a high-efficiency perovskite solar cell structure, incorporating a Cs0.05(FA0.77MA0.23)0.95Pb(I0.77Br0.23)3 as absorber, PCBM as the electron transport layer (ETL), and CuSbS2 as the hole transport layer (HTL). First-principles calculations were conducted to explore the electronic and optical properties of these materials, revealing a high absorption coefficient of approximately 105 cm-1, making the perovskite an excellent absorber. The SCAPS-1D simulation tool was employed to evaluate the photovoltaic performance of the ITO/PCBM/mixed perovskite/CuSbS2/Ag device. Various factors such as different HTLs and ETLs, absorber thickness, ETL and
