Model the effect of different Hole Transport Inorganic materials on performance of perovskite solar cells

Abstract

Effect of different Hole transport material inorganic materials on performance of perovskite solar cells is investigated using Comsol Multiphysics by solving the Helmholtz equation derived from Maxwell’s equation. The study aims to highlight the change in perovskite solar cell performance caused by using different kinds of inorganics materials as hole transporting materials such as (MoO_3 ,Cu_2 O ,CuI ,CuSCN ,NiO_x). The J -V characteristics for different inorganic materials as hole transporting materials are simulated. The simulation results show that perovskite solar cells based on MoO_3 as hole transporting materials has higher Voc , better fill factor (FF) and an overall power conversion efficiency (18.15%). While, CuSCN has the lowest efficiency 10.34 % due to the high potential barrier faced by hole transporting materials in CuSCN/CH3 NH3 PbI3 interface. Thus, inserting MoO_3 in perovskite solar cell design may possibly be considered as novel designing for future perovskite solar cells.
