Abstract

In this paper, the impact of ETL/Absorber interface layer has been studied on the efficiency of perovskite solar cell using perovskite materials such as methyl ammonium lead trihalide (MAPbX3, MA=CH3NH3, X: I, Br, Cl) through the SCAPS tool. Modeling and the numerical simulation have been performed with electrical properties of the MAPbX3 material used as the active layer and calculated different parameters such as open-circuit voltage (Voc), power conversion efficiency (PCE), short-circuit current density (Jsc) and fill factor (FF) correspondingly. The interface layer occurs between ETL (TiO2) as the electron transport layer and absorber layer (CH3NH3PbX3, X: I, Br, Cl) have been considered in the construction of perovskite solar cell with inorganic CuI material acting ashole transport layer (HTL). The capacitance–frequency (C-F) and capacitance-voltage (C-V) characteristics for all above-studied perovskite solar cell have been calculated. The simulated results show that consideration of ETL/Absorber interface layer effects on the MAPbI3 has better performance parameters (FF=75.59, PCE=15.51, Voc=0.74, Jsc=27.71mAcm-2) in comparison of MAPbBr3 and MAPbCl3.
