Optimization of the Perovskite Layer for High Efficiency Perovskite Solar Cells

Perovskite solar cells are among the most widely researched emerging solar cells in recent years because of their improved energy conversion efficiency. However, its stability remains one of the issues for its large-scale deployment. We fabricated and optimized the Perovskite layer using spin coating methods. Characterization tools such as scanning electron microscope, X-ray fluorescence and UV-Visible Spectroscopy were used to optimize the performance of the Perovskite layer and thereby improving the overall efficiency of the solar cell. We investigated the effects of layers’ thickness and Perovskite’s doping concentration. We used SCAPS-1D Numerical simulations to confirm the experimental results.
