Improve Efficiency and Reduce Cost of Perovskite-Based Solar Cell

This work utilizing "RSOFT’s Diffract MOD and solar Cell Utility" based on RCWA calculation to analyze the behavior of the solar cell and to compute the PCE (power conversion efficiency) (RSoft CAD photonic device tools) was used to study the effect of the materials used in the different layers of the perovskite-based solar cell on the efficiency of this cell. We used perovskite as the active layer, PDMS as a window layer, ZnS as ETL (electron transport layer) and AZO as HTL (hole transport layer). and make a change of reflective layer from Au (Gold) to different reflective layers candidate have been suggested. So that in the beginning we used gold as a reflective layer, we found the efficiency of this cell estimated at 21.43%, we changed the reflective gold layer with different other reflective layers such as (Al, Cr, Be, Ni, Ti…) in order to increase the efficiency of this solar cell and reduce the cost because the cost of gold is high, we found that the efficiency increased in most of the candidates to reach 24.23% when Be was placed as a reflective layer, and this is a significant increase in the efficiency of the solar cell.
