Simulation Insights into Perovskite Active Layers for Enhancing Solar Cell Efficiency

Abstract

This study explores the performance of perovskite solar cells with various absorber materials, including MASnI3, CH3NH3SnI3, CsPbI3, and CsSnGeI3, analyzing key metrics such as efficiency, open-circuit voltage (Voc), short-circuit current density (Jsc), and fill factor (FF). Simulations using SCAPS software provided baseline data, which were further validated and extended using advanced computational techniques. Sensitivity analyses revealed the impact of parameters like bandgap energy and carrier mobility, while layer optimization and circuit modeling offered insights into enhancing device performance. Comparative analysis and real-world simulations bridged the gap between lab results and practical applications, supported by machine learning models to predict efficiencies for novel materials. This comprehensive approach aids in optimizing perovskite solar cells for future applications.
