Analysis and Optimization of MASnPbI3-based Single Junction Solar Cells for High Power Conversion Efficiency

The MASnPbI3-based perovskite solar cells were thoroughly analysed in the SCAPS study, which revealed their high power conversion efficiency and low production cost, making them a promising technology for photovoltaic applications.

. This result emphasizes the importance of optimizing the thickness of the MASnPbI3 material to enhance the performance of perovskite-based solar cells. Optimizing the thickness of the MASnPbI3 layer is critical to improving the PCE of MASnPbI3 based solar cells, which is vital for their widespread commercialization and deployment. Also the bulk defect density (BDD) of the MASnPbI3 layer should be as low as possible for the best PV characteristics of the cell. The results of the SCAPS study serve as a basis for future research in advancing the development of high-performance perovskite solar cells and their integration into photovoltaic systems.
