Perovskite solar cells (PSCs) are regarded as extremely efficient and have significant potential for upcoming photovoltaic technologies due to their excellent optoelectronic properties. However, a few obstacles, which include the instability high costs of production lead-based PSCs, hinder commercialization. In this study, performance cell with configuration FTO/CdS/BaZrS3/HTL/Ir was optimized by varying thickness perovskite layer, hole transport temperature, electron layer (ETL)’s defect density, absorber energy band, work function back contact. Various layers (HTLs), including Cu2O, CuSCN, P3HT, PEDOT:PSS, were assessed select best materials that would achieve stability in PSC devices. At optimal levels, PEDOT:PSS reached maximum power conversion efficiency (PCE) 18.50%, while Cu2O exhibited PCE 5.81, 10.73, 9.80%, respectively. The attributed better band alignment between and, thus, low recombination photogenerated charges. other parameters device short-circuit current density (Jsc) 23.46 mA cm−2, an open-circuit voltage (Voc) 8.86 (V), fill factor (FF) 8.90%. This study highlights chalcogenide-based PSCs stable alternative traditional cells, successful optimization paving way future research on eco-friendly scalable methods.
