Perovskite solar cells have garnered significant attention due to their outstanding optoelectronic properties, ease of fabrication, and cost-effectiveness, making them a promising candidate for next-generation photovoltaic technologies. However, CsPbIBr2-based perovskites currently face critical challenges regarding limited efficiency relatively poor long-term stability, hindering broader commercial applications. In this study, we systematically investigated the morphological effects induced by different solvents, including dimethylformamide (DMF), N-methyl-2-pyrrolidone (NMP), dimethyl sulfoxide (DMSO), on formation characteristics lead bromide (PbBr2) complexes. Further optimization was achieved through innovative incorporation trimesoyl chloride (TMC) doping into perovskite precursor solution. The optimized solution subsequently processed using spin-coating annealing method, resulting in high-quality CsPbIBr2 thin films with improved properties. experimental results demonstrated remarkable enhancement power conversion (PCE), an increase from initial value 6.2% up 10.2%. Furthermore, exhibited excellent maintaining over 80% after continuous aging 250 h ambient air conditions. This study presents effective strategy controlled compositional engineering wide-bandgap materials, providing step forward advancement technology.
