Abstract

In this investigation, a numerical modeling was developed out using SCAPS-1D to optimize produvtivity levels of a perovskite photovoltaic (PV) cell device utilizing Formamidinium tin Iodide as an active layer (

{FA = C H ({NH}_{2})}_{2}

) with graphene oxide (GO) serving as the buffer layer. The exceptional electronic and optical characteristics resulted in a notable enhancement of the performance of hybrid organic–inorganic halide perovskite. This paper aims to examine various parameters that influence the effectiveness of the PV cell, including the layers thickness of the absorber (FASnI₃) and the GO buffer, the temperature effects, defect density for the GO/

interface, and the resistance R_s in series and in shunt R_SH. The FTO/

FTO/GO/FASnI3/Cu太阳能电池的性能最大化：使用SCAPS-1D进行高级分析，效率达到20.63%

在这项研究中，利用SCAPS-1D建立了一个数值模型，以优化钙钛矿光伏（PV）电池器件的生产力水平，该器件利用碘化甲脒锡作为活性层(FASnI3；FA=CH(NH2)2)，氧化石墨烯（GO）作为缓冲层。特殊的电子和光学特性使杂化有机-无机卤化物钙钛矿的性能得到显著提高。本文旨在研究影响光伏电池效率的各种参数，包括吸收层（FASnI3）和氧化石墨烯缓冲层的厚度、温度效应、氧化石墨烯/氧化石墨烯接口的缺陷密度，以及串联和并联RSH中的电阻Rs。FTO/FASnI3/GO/Cu结构的峰值性能为：开路电压（VOC）为1.044 V，短路电流（JSC）为28.69 mA·cm-2，填充系数（FF）为68.88%，功率转换效率（PCE）为20.63%。该器件参数的优化，表明了合成高效无铅fasni3基光伏电池的可能性。
