Özet
In recent years, perovskite solar cells (PSCs) have gained significant attention as highly efficient photovoltaic (PV) devices. 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 Authors
