Despite achieving record levels of power conversion efficiency (PCE), the commercialization of Pb-based PSCs has been hindered by factors such as lead toxicity and stability. As a potential alternative, Pb-free Bi-based all-inorganic PSCs show promising efficiency. In this study, we utilized the Solar Cell Capacitance Simulator (SCAPS-1D) to optimize a Bi2FeCrO6-based (BFCO) PSC and analyzed the impact of absorber thickness, doping concentration, and external parameters on its PV performance. We have found that an optimized n-i-p architecture with an absorber thickness of 150 nm yielded a maximum PCE of 7% at ambient temperature (with open-circuit voltage, short-circuit current density, and fill factor of 1.12 V, 12 mA/cm2, and 53.7%, respectively). Furthermore, we found that decreasing the defects density Nt of the BFCO layer below 1013 cm−3 could increase the PCE to above 10%. Our findings also revealed that the temperature had a negative effect on the solar cell, and the optimum conditions were at ambient 300 K. These results are encouraging for advancing Pb-free PSCs and enhancing their design and integration into tandem SCs. © 2024 The Authorseninfo:eu-repo/semantics/closedAccessBFCOPerovskitePV parametersSCAPS-1DSolar cell simulationThin filmArticle10.1016/j.ijleo.2024.1716593022-s2.0-85187232374Q1
