Investigation of a Perovskite Solar Cell and Various Parameters Impact on Its Layers and the Effect of Interface Modification by Using P3HT as an Ultrathin Polymeric Layer Through SCAPS-1D Simulation

Recently, renewable energy sources such as solar have gained much attention for electricity generation because of their easy access and infinite resources. Solar cells are a good choice this goal. Among the various that already been studied, perovskite (PSCs) recently is interested in researchers due to tremendous improvement system performance efficiency. This type cell divided into several layers, each which has its role structure cell. Front Contact/Electron transporting material/Absorbent (perovskite)/Hole layer/Back Contact. The overall these shown maximum efficiency about 22% cells. However, suffers from stability problems, especially at junction point between HTM (absorber) layer, despite cost-effectiveness advantages. To solve problem, recent studies transferred study called interface engineering. In study, mentioned interfaces modified by some materials regular stable structures polymers. Many polymeric modifiers studied years. them, P3HT (Poly(3-hexylthiophene-2,5-diyl)) provided best results. paper, first, effect different layer properties thickness charge carrier density were investigated optimal parameters obtained one using SCAPS-1D (Solar Cell Capacitance Simulator) software. Then we simulated modifier structure. results showed adding an ultrathin film perovskite, device was improved enhanced. final with 26.5%.
