This research explores the performance of inverted perovskite solar cells (IPSC) using the General-purpose Photovoltaic Device Model (GPVDM) software. Alternatively, inorganic p-type semiconductors, especially NiOx which is the most widely used HTL, can provide intrinsically higher stability and exhibit lower cost than organic polymer-based HTL. The device structure in the simulation comprises ITO/NiOx/MAPbI3/C60/BCP/Ag. Various factors, including layer thickness, electrical parameters, absorption coefficient and refractive index of each layer, can influence the simulated IPSC's performance. GPVDM provides a comprehensive simulation platform to investigate the impact of these factors on the power conversion efficiency (PCE) of IPSCs. The simulation results from GPVDM exhibit a remarkable match and good agreement with achieving efficiencies of 17.35% and 17.57%. To optimize the results, two cases are analyzed and compared. Notably in Case 2, which employs experimental data for α and n from earlier research, outperforms the preceding journal with an efficiency of 18.23% compared to 17.57%. These simulation findings serve as a valuable guide for the fabrication of IPSCs utilizing NiOx, BCP, and C60 as active layers, offering insights into enhancing their performance.
