“…But it's important to recognize that the specific lead-containing perovskite compounds, such MAPbI 3 , raise questions about stability and environmental effect, which might prevent them from being widely used in solar cell technology. Development of a bifacial structure is one way to address this issue, utilizing superior optoelectronic characteristics including a less exciton binding energy, better absorption coefficient, and higher carrier transport 5 – 7 . This bifacial structure corresponds to a group in the periodic table that is similar to its lead-containing counterpart, with a direct bandgap of 1.3 eV falling within the absorber range 8 .The fundamental layers of the typical PSC structure are contact electrodes, transparent glass, the hole transport layer (HTL), the absorber layer (Abs), and the electron transport Layer (ETL) (see Fig.…”

The most rapidly expanding type of solar cells are the Perovskite Solar Cells (PSCs), because of its high device performance, ease of synthesis, high open-circuit voltage, and affordability. Despite these advantages, the development of perovskite-based solar cells continues to be impeded by the issues with perovskite stability and the utilization of the hazardous heavy element lead (Pb). The study emphasizes on the bifacial structure that maintains the conventional absorber layer and electron transport layer (ETL) in the optimized PSC structure. This study employs SCAPS software for device simulation to comprehensively analyze how various parameters affect the performance of solar cells. Additionally, doping concentration variation in both ETL and HTL are explored. The simulation reveals that changing device structure from monofacial to bifacial significantly influences PSC performance, demonstrating that optimizing individual layers effectively enhances overall solar cell performance. The optimized structure achieves impressive PSC performance metrics through parametric analysis, such as voltage (VOC) of 1.18 V, fill factor (FF) of 82.24%, current density (JSC) of 27.12 mA/cm2, power conversion efficiency (PCE) of 27.90% for an incident solar spectrum from the ETL side, and power conversion efficiency (PCE) of 19.86% for an incident solar spectrum from the HTL side, the calculated bifaciality factor (BF) for this structure is 71.18%.
