Thermal Stability and Photovoltaic Enhancement of Double Perovskite (Cs₂InSbCl₆) Based Solar Cell (p-i-n) through Thickness and Bandgap Optimization
This study utilizes SCAPS-1D simulations to demonstrate that optimizing the thickness and bandgap of a Cs₂InSbCl₆-based p-i-n solar cell with an Fe/CuO/CdS/TiO₂ heterostructure yields a high power conversion efficiency of nearly 28% with reduced recombination losses and acceptable thermal stability, establishing it as a promising candidate for next-generation photovoltaics.
