In this work a lead free perovskite solar cell structure is proposed with NiO as the hole transport material (HTM), CH₃NH₃SnI₃ as the perovskite absorber material and PCBM (phenyl C₆₁ butyric acid methyl ester) as the electron transport material (ETM). Numerical analysis of the designed solar cell is performed using Solar Cell Capacitance Simulator (SCAPS-1D) program. The power conversion efficiency (PCE) of the optimized device stack is found to be above 29% with V_oc = 0.98 V, J_sc = 34.86 mA/cm², FF = 85.64%. The lead free perovskite solar cell with different HTM and ETM may be investigated for high PCE.

以NiO为空穴传输材料，PCBM为电子传输材料的高效无铅钙钛矿太阳能电池的数值分析

在这项工作中，提出了一种无铅钙钛矿太阳能电池结构，其中NiO作为空穴传输材料（HTM），CH ₃ NH ₃ SnI ₃作为钙钛矿吸收材料，PCBM（苯基C ₆₁丁酸甲酯）作为电子传输材料（ETM）。使用太阳能电池电容模拟器（SCAPS-1D）程序对设计的太阳能电池进行数值分析。发现最佳器件堆叠的功率转换效率（PCE）高于29％，其中V _oc  = 0.98 V，J _sc  = 34.86 mA / cm ²，FF = 85.64％。可以对具有不同HTM和ETM的无铅钙钛矿太阳能电池进行高PCE研究。
