چکیده

The Cs2AgBi0.75Sb0.25Br6 based perovskite solar cell (PSC) has demonstrated a high power conversion efficiency (PCE > 16%) and exceptional air stability. A comprehensive study of the interfaces in perovskite solar cells, coupled with the optimization of many parameters, is still necessary for further enhancement in PCE. This study quantitatively analyzes lead-free Cs2AgBi0.75Sb0.25Br6 utilizing a solar cell capacitance simulator (SCAPS–1D). The electron transport layer (ZnO) and the hole transport layer (Cu2O) were analyzed comparably. The work function, temperature, and thickness of the PSC layers have been meticulously examined. The results indicate that the efficiency of the device is significantly influenced by the thickness of the absorber layer. The simulation determined the maximum PCE of Cs2AgBi0.75Sb0.25Br6-based PSCs to be 16.23%, at thickness 0.1μm of absorber layer with an open circuit voltage (Voc) of 1.3666 V, a short-circuit current density (Jsc) of 23.825 mA/cm², and a fill factor (FF) of 49.84%. Our exceptional results unequivocally indicate that Cs2AgBi0.75Sb0.25Br6- based PSCs are poised to emerge as the most efficient single-junction solar cell technology in the near future.
