Methylammonium lead halide (${{\rm MAPbI}_3}$) is widely used as perovskite absorber material in thin-film solar cell technology because of its eminent cell performance. Recently, formamidinium lead iodide perovskite (${{\rm FAPbI}_3}$) has received great attention because of its optimum bandgap value closer to the infrared single junction range. In this paper, a suitable combination of hole transporting material (HTM) and electron transporting material (ETM) is determined to achieve higher efficiency compared to existing structures utilizing an ${{\rm FAPbI}_3}$ absorber. The proposed structure uses two stable metal oxides as HTM (${{\rm NiO}_X}$) and ETM (${{\rm SnO}_2}$). A comparative numerical analysis of solar cell performance is shown among four different HTM materials using the Solar Cell Capacitor Simulator (SCAPS-1D). Performance evaluation is also carried out for three different compositions of ${{\rm FAPbI}_3}$ having different band gaps with respect to absorber thickness. Optimized absorber thickness, HTM and ETM doping density, and absorber defect density are enumerated using numerical simulation. By deploying the optimized parameters, maximum power conversion efficiency is found to be 26.23%. Later on, effects of ${R_{\rm{series}}}$ and ${R_{\rm{shunt}}}$ on ideal solar cell performance are analyzed using numerical simulation.

高效FAPbI ₃基钙钛矿太阳能电池的性能评估和比较分析

甲基铵卤化铅（$ {{rm MAPbI} _3} $）由于其出色的电池性能而被广泛用作薄膜太阳能电池技术中的钙钛矿吸收材料。最近，甲酰胺碘化钛酸钙钛矿（$ {{\ rm FAPbI} _3} $）由于其最接近红外单结范围的最佳带隙值而备受关注。在本文中，与使用$ {{\ rm FAPbI} _3} $吸收剂的现有结构相比，确定了合适的空穴传输材料（HTM）和电子传输材料（ETM）的组合以实现更高的效率。拟议的结构使用两种稳定的金属氧化物作为HTM（$ {{\ rm NiO} _X} $）和ETM（$ {{\ rm SnO} _2} $）。使用太阳能电池电容器模拟器（SCAPS-1D）显示了四种不同的HTM材料之间的太阳能电池性能的比较数值分析。还针对具有相对于吸收体厚度的不同带隙的三种不同成分的$ {{rm FAPbI} _3} $进行了性能评估。使用数值模拟列举了优化的吸收体厚度，HTM和ETM掺杂密度以及吸收体缺陷密度。通过部署优化参数，发现最大功率转换效率为26.23％。随后，使用数值模拟分析了$ {R _ {\ rm {series}} $和$ {R _ {\ rm {shunt}}} $对理想太阳能电池性能的影响。
