This study presents the fabrication, characterization, and optimization of planar-heterojunction Cs₃Bi₂I₉ perovskite solar cells, supported by SCAPS-1D simulations. Experimental results reveal that among fabricated devices (A1, A2, A3), sample A3 demonstrates highest efficiency, with a 0.72% improvement over its counterparts. superior performance is attributed to larger crystallite size, reduced strain, minimal dislocation density, enhanced carrier mobility. These properties collectively minimize recombination losses, increase lifetime, improve charge transport collection. To further understand enhance devices, was employed simulate model. By experimental parameters such as minority lifetime absorber layer thickness, efficiency device improved significantly in simulated optimized model, achieving notable short-circuit current density (JSC). The highlights importance balancing material architecture losses efficiency. work also explores relationship between diffusion length, film emphasizing their combined impact on cell performance. While minor discrepancies were observed data, they fell within an acceptable range, validating simulation approach. findings underline potential targeted structural push cells closer theoretical limits. success offers valuable insights for advancing photovoltaics.
