In this work, our aim is to perform modeling and numerical simulation of a solar cell using the SCAPS-1D simulation program. The studied solar cell has an N-I-P type structure, with its active layer based on a hybrid (organic-inorganic) semiconductor called “methylammonium tin triiodide perovskite” (CH3NH3SnI3). This semiconductor has demonstrated its efficiency in the field of photovoltaics.

The objective of this study is primarily focused on improving the performance of the solar cell, specifically enhancing the reproducibility and stability of perovskite solar cells, as they tend to degrade rapidly. To achieve this, we have proposed the use of ZnO and Spiro-OMeTAD as charge transport layers (ETL and HTL, respectively) and varying the thickness of the active layer to obtain the optimal parameters that ensure the proper functioning of the cell.
