Optimation of Layers Thickness Design of Perovskite Solar Cell (PSC) Using GPVDM Simulation

Abstract

In this research, perovskite solar cells by configuring ITO/PEDOT:PSS/CH₃NH₃PbI₃/ZnO/Al changed to optimize their performance. Modifications are made by varying the thickness of each layer to increase the ideal thickness with an optimal power conversion efficiency (PCE) value. This research used GPVDM software to study several power conversion efficiency (PCE) parameters of ITO/PEDOT:PSS/CH₃NH₃PbI₃/ZnO/Al solar cells. The results of the study show that the power conversion efficiency (PCE) can be increased by adjusting the thickness of the coating, in this study the ideal thickness with the highest power conversion efficiency 25.75% in 1x10^-8 m of ITO, 1x10^-6 m of PEDOT:PSS, 4x10^-7 m of CH₃NH₃PbI₃, 1x10^-8 m of ZnO and 1x10^-9 m of Al.
