%X 本文利用Scaps-1d软件设计了甲基铵碘化锗(MAGeI<sub>3</sub>)作为光吸收层&#65292;硫氰酸亚铜(CuSCN)作为空穴传输层&#65292;TiO<sub>2</sub>作为电子传输层&#65292;ITO和Au分别为前、后接触电极的Ge基钙钛矿太阳能电池。研究了空穴传输层的带隙、受主掺杂浓度、钙钛矿吸收层的缺陷态密度&#65292;以及MAGeI<sub>3</sub>/CuSCN界面缺陷等关键参数对器件性能的影响&#65292;优化后&#65292;器件的光电转换效率为33.82%&#65292;相比初始参数下得到的光电转化效率24.07%&#65292;提高了9.75%。<br>This paper designs a perovskite solar cell based on Ge-based using Scaps-1d software, with methylammonium germanium iodide (MAGeI<sub>3</sub>) as the light absorption layer, copper(I) thiocyanate (CuSCN) as the hole transport layer, TiO<sub>2</sub> as the electron transport layer, and ITO and Au as the front and back contact electrodes, respectively. The effects of key parameters such as the bandgap of the hole transport layer, acceptor doping concentration, defect state density of the perovskite absorption layer, and interface defects between MAGeI<sub>3</sub> and CuSCN on device performance are investigated. After optimization, the power conversion efficiency of the device reaches 33.82%, which is 9.75% higher than the initial efficiency of 24.07%.
