摘要

Perovskite solar cells (PSC) have made a great contribution to all-round development in the field of solar cells. This work focuses on lead-free perovskite with improved performance. The proposed perovskite for designing the solar cell (SC) is CH3NH3SnI3 (MASnI3). The choice of proper charge transport layers (CTL) for PSC structures is key to achieving greater efficiency and stability. Here, ZnMgO is used as the electron transport layer (ETL) and CBTS as the hole transport layer (HTL).To improve all photovoltaic performance parameters, the SCAPS-1D simulation software is used to investigate, a novel solar cell structure (ITO/ZnMgO/ \(\:{\text{M}\text{A}\text{S}\text{n}\text{I}}_{3}\) /CBTS/Au). Series and shunt resistance are kept off, and other parameters such as the thickness of different layers, donor and acceptor densities, and temperature are varied to optimize the power conversion efficiency. The optimized power conversion efficiency of the device with the proposed structure is 30.17%, which provides a channel to develop more efficient SC and opens another gateway for experimentalists to design high-performing solar cells. Enhanced efficiency can be explained on the basis of the increased range of absorption spectrum of radiation.
