Numerical Modeling and Optimization of Lead-Free Hybrid Double Perovskite Solar Cell by Using SCAPS-1D

Abstract

The highest power conversion efficiency (PCE) for organic-inorganic perovskite solar cells based on lead is reported as 25.2% in 2019. Lead-based hybrid perovskite materials are used in several photovoltaics applications, but these are not highly favored due to the toxicity of lead and volatility of organic cations. On the other hand, hybrid lead-free double perovskite has no such harm. In this research study, SCAPS numerical simulation is utilized to evaluate and compare the results of perovskite solar cell based on double perovskite FA2BiCuI6 and standard perovskite CH3NH3PbI3 as an active layer. The results show that the power conversion efficiency obtained in the case of FA2BiCuI6 is 24.98%, while in the case of CH3NH3PbI3, it is reported as 26.42%. This indicates that the hybrid organic-inorganic double perovskite FA2BiCuI6 has the ability to replace hybrid organic-inorganic perovskite CH3NH3PbI3 to expand next-generation lead-free harmless materials for solar cell applications.
