Photovoltaic performance analysis of CH3NH3PbI3 perovskite solar cell using SCAPS simulation

Abstract

This study is focused on the design and photovoltaic performance analysis of lead (Pb) based perovskite solar cell using Solar Cell Capacitance Simulator (SCAPS). Perovskite materials display high power conversion efficiency and cheap manufacturing costs. This makes them an exciting candidate for the application in renewable energy technology. This work is focused on the construction and design of perovskite solar cell by introducing TiO₂ as electron transporting layer (ETL) and PEDOT:PSS as hole transporting layer (HTL). The device structure for the simulation is Au/PEDOT:PSS/CH₃NH₃PbI₃/TiO₂/ITO. Numerical simulation on photovoltaic parameters such as open circuit voltage (V_OC), short circuit current density (J_SC), fill factor (FF), and power conversion efficiency (PCE), as well as short-circuit current density versus voltage (J-V) characteristics, have been studied. The consequences of doping concentration, absorber layer thickness, electron affinity of absorber layer, thickness of ETL, and HTL on photovoltaic performance have been investigated. The simulated perovskite solar cell offers an efficiency of 23.10%, an open circuit voltage (V_OC) of 1.093 ​V, and a short-circuit current density (J_SC) of 24.634 ​mA/cm². The optimum thickness of the absorber layer, HTL, and ETL layer has also been calculated for better power conversion efficiency of the device.
