Parametric Optimization and Mathematical Analysis of Dual Halide Lead Free Perovskite Solar Cell

The scientific community has recently taken an interest in perovskite solar cells, often known as PSCs. Dual halide PSC has the best efficiency reported in the literature at 20.9%. The purpose of this work is to improve a lead-free dual halide photovoltaic (PSC) by modifying the material of the hole transport layer (HTL) and the electron transport layer (ETL), as well as regulating the thickness of the absorber layer. In order to evaluate the device, the following metrics are taken into consideration: fill factor (FF), power conversion efficiency (PCE), open circuit voltage (VOC), and short circuit current density (JSC). With optimization, the gadget can reach an efficiency level of 24.03%. Further investigation into a tandem or dual structure method may be possible with this work.
