摘要

The La2NiMnO6 double perovskite material holds significant potential for photovoltaic applications due to its exceptional magnetic and electronic properties. This research scrutinizes the performance optimization of La2NiMnO6-based Perovskite Solar Cell (PSC) through simulations conducted using the Simulation Software SCAPS-1D. The domination of resistances, Rs (series), Rsh (shunt) and absorber layer thickness on the photovoltaic Standards- fill factor (FF), efficiency, open-circuit voltage (Voc), and short-circuit current density (Jsc) - was systematically analyzed. Optimal performance was achieved at an absorber breadth of 400 nm, with Rs and Rsh values finely tuned to balance resistive losses and leakage currents. The optimized device exhibits a maximum power conversion efficiency (PCE) of 19.28%, with a short-circuit current density (Jsc) of 27.08 mA/cm² and a fill factor (FF) of 36.93% at an absorber thickness of 400 nm. The results highlight the significant influence of resistive parameters and thickness optimization on device performance. The study underscores the pivotal significance of interfacial and material optimization in enhancing the overall efficiency of PSC. Additionally, it offers an in-depth strategy for boosting the performance of lead-free perovskite materials, addressing the urgent demand for eco-friendly variants to lead-based perovskites. The findings contribute to advancing effort of advancing renewable energy technologies by offering practical guidelines for material selection and device architecture.
