Abstract

Lead-free perovskite materials have emerged as the most feasible option for photovoltaics to address the issue of toxicity and better performance. This study aims to design and enhance the performance of lead-free methylammonium (MA) and formamidinium (FA) compound (FAMASnGeI₃)-based flexible perovskite solar cell (FPSC) by utilizing the solar cell capacitance simulator 1-D (SCAPS-1D). The optimization of various geometrical parameters and charge densities of the absorber and charge transport layers show the improvement in power conversion efficiency (PCE). We have obtained

${V} _{\text {oc}}$

of 0.87V,

${J} _{\text {sc}}$

of 45.7 mA/cm², fill factor (FF) of 75.3%, and PCE of 29.9%. The obtained results were compared with similar existing research based on various absorber layers. It was found that the selected absorber layer improves the performance of FPSCs.

无铅柔性钙钛矿太阳能电池的设计与性能提升：数值方法

无铅钙钛矿材料已成为光伏发电解决毒性和更好性能问题的最可行选择。本研究旨在利用太阳能电池电容模拟器1-D （SCAPS-1D）设计并提高无铅甲基铵（MA）和甲脒（FA）化合物（FAMASnGeI3）基柔性钙钛矿太阳能电池（FPSC）的性能。对吸收层和电荷输运层的几何参数和电荷密度进行优化，可以提高功率转换效率。我们得到${V} _{\text {oc}}$为0.87V, ${J} _{\text {sc}}$为45.7 mA/cm2，填充系数（FF）为75.3%，PCE为29.9%。并将所得结果与已有的基于不同吸收层的类似研究结果进行了比较。结果表明，所选择的吸收层可以提高FPSCs的性能。
