Abstract

Halide-based perovskite materials offer significant advantages like high efficiency, ease of production, and costeffectiveness. Recently, lead-free titanium-based inorganic perovskite solar cells (PSCs) have gained attention due to environmental concerns about lead. Titanium’s non-toxicity, durability, and affordability make it a promising alternative. Using SCAPS-1D software, this study optimized the PSC performance by adjusting parameters such as perovskite layer thickness, defect density, and doping concentration. The optimized CH3NH3SnBr3/Cs2TiBr6 PSC achieved a power conversion efficiency of 27.86%, highlighting its potential for advancing research in lead-free PSCs.
