摘要

三碘化铯锡锗（CsSn0.5Ge0.5I3）是一种性能优良的无机卤化物，近年来受到广泛关注。在本研究中，设计了一种无铅钙钛矿太阳能电池结构，其中硒化锌作为电子传输层（ETL），CsSn0.5Ge0.5I3作为钙钛矿吸收层，PTAA[聚（双[4-苯基]{2,4,6-trimethylphenyl}amine)]作为空穴传输层（HTL）。为了更实际地理解太阳能电池，已经检查了几个参数，如吸收层厚度、缺陷密度、吸收层掺杂浓度、界面缺陷和工作点温度。SCAPS-1D模拟器用于对所提出的装置进行分析。该装置的PCE为23.15%，VOC=1.07 V、 JSC=27.24 mA/cm2，在800时FF=78.82% nm厚度的CsSn0.5Ge0.5I3吸收层。选择最佳的材料参数和易于制造适用于开发高效环保的钙钛矿太阳能电池。

Theoretical study of lead-free perovskite solar cell using ZnSe as ETL and PTAA as HTL

Cesium tin germanium triiodide (CsSn0.5Ge0.5I3) is one of the proficient inorganic halides the perovskites for better stability that has received wide attention in recent years. In the present study, a lead-free perovskite solar cell structure is designed with Zinc selenide as the electron transport layer (ETL), CsSn0.5Ge0.5I3 as the perovskite absorber layer, and PTAA [Poly(bis[4-phenyl]{2,4,6-trimethylphenyl}amine)] as the hole transport layer (HTL). For a more practical understanding of the solar cell, several parameters such as absorber thickness, defect density, doping concentration of absorber layer, interface defects, and working point temperature have been examined. SCAPS-1D simulator is used for the analysis of the proposed device. The PCE of the device has been obtained as 23.15% with VOC = 1.07 V, JSC = 27.24 mA/cm2, FF = 78.82 % at 800 nm thickness of CsSn0.5Ge0.5I3 absorber layer. Selecting the best material parameters and easy fabrication is suitable for developing highly efficient and environmentally friendly perovskite solar cells.
