CsBiAgI is a lead-free inorganic perovskite material exhibits exceptional photoelectric characteristics and great environmental stability. HTL/CsBiAgIis/ETLs solar cells was investigated numerically by using SCAPS 1-D Capacitance Simulator. IGZO, TiO, WO, MoO, and SnO have been chosen as ETLs, while CuO, CuI, and MoO are as HTLs. The values of electrical parameters were calculated as function of thickness of the absorber layer, ETLs, HTLs, interface defect densities, doping densities, and working temperature. Comparative study shows that best configuration of obtain solar cell is MoO/CsBiAgI/IGZO. The obtain value of Jsc, Voc, FF and PCE are 23.80 mA/cm, 1.193 V, 83.46 %, 23.711 % respectively. The value of quantum efficiency is 80-90 % in the range of 350-750 nm. These results will open the door for the widespread use of stable and environmentally friendly perovskite solar cells by providing theoretical recommendations for high performance of Cs2BiAgI6 based photovoltaic solar cells (PSCs).
CsBiAgI是一种无铅无机钙钛矿材料，具有优异的光电特性和良好的环境稳定性。利用SCAPS 1-D电容模拟器对HTL/CsBiAgIis/ETLs太阳能电池进行了数值研究。已选择IGZO、TiO、WO、MoO和SnO作为电子传输层（ETLs），而CuO、CuI和MoO作为空穴传输层（HTLs）。计算了电学参数值与吸收层、电子传输层、空穴传输层厚度、界面缺陷密度、掺杂密度和工作温度的函数关系。对比研究表明，获得的最佳太阳能电池结构是MoO/CsBiAgI/IGZO。获得的短路电流密度（Jsc）、开路电压（Voc）、填充因子（FF）和光电转换效率（PCE）值分别为23.80 mA/cm²、1.193 V、83.46%、23.711%。在350 - 750 nm范围内，量子效率值为80 - 90%。这些结果将为基于Cs2BiAgI6的高性能光伏太阳能电池（PSCs）提供理论建议，为稳定且环保的钙钛矿太阳能电池的广泛应用打开大门。
