Investigating the Performance Parameters of Nanostructure Lead Free Perovskite Solar Cell

Abstract

This paper describes how an organic/inorganic nanostructure perovskite photovoltaic solar cell is simulated and optimized. The simulated solar cell consists of a sandwiching of ETL/ Perovskite/Cu2O with Cu2O Hole Transportation Layer (HTL) and as a ETL layer different materials like TiO2, ZnO, SnO2, CdZnS , C60, Ws2 PCBM, Cds and IGZO being the electron transport layer (ETL) and).The experimental results in the study effort were in excellent agreement with the device features and various materials are modeled. The gadget had a typical n-i-p intersection configuration. The optimum absorber thickness effects of absorbing quality, interface defect density, ETM & HTM effects and the front and rear interface contact electrodes were all investigated. CH3NH3SnI3, HTL/ CH3NH3SnI3, and ETL/ CH3NH3SnI3 are the main characteristics of the open circuit voltage. The current is primarily measured by the thickness of CH3NH3SnI3 in short-circuit systems, since both the VBO (Valence Band Offset) and the LBO (Leading Band Offset) values are controlled. The front-back electrode interface significantly affects the filling factor. It is worth noting that in ideal conditions, power conversion efficiency is reached. Real devices with a PCE were produced after the initial optimization of the CH3NH3SnI3 absorber layer preparation. From a theoretical and experimental standpoint, it may be useful in recommending and enhancing device strategy.
