基于CuBr<sub>2</sub>二维钙钛矿的全固态太阳能电池

摘要

制备了2种基于CuBr₂的有机无机二维钙钛矿，（p-F-C₆H₅C₂H₄-NH₃）₂-CuBr₄（P1）、（CH₃（CH₂）₃NH₃）₂-CuBr₄（P2），将其作为新型的空穴传输材料应用于全固态太阳能电池；采用紫外可见吸收光谱（UV/Vis）、X射线衍射（XRD）、扫描电镜（SEM）对P1、P2薄膜进行了物理表征，并对器件进行了光电性能测试和阻抗分析；研究了三氟甲磺酰亚胺锂盐（Li-TFSI）和叔丁基吡啶（TBP）掺杂P1、P2对器件性能的影响。结果表明：Li-TFSI和TBP的掺杂可提高P1、P2的空穴电导率，改善电荷转移能力；掺杂后基于P1、P2的器件分别获得了0.50%和0.56%的光电转化效率。

Abstract：

Two two-dimensional organic-inorganic cupric bromide perovskites (p-F-C₆H₅C₂H₄-NH₃)₂-CuBr₄(P1)and (CH₃(CH₂)₃NH₃)₂-CuBr₄(P2)were prepared and applied to solid solar cells as novel hole transport materials (HTMs). The P1 and P2 films were characterized by UV/Vis、XRD and SEM. The photocurrent measurement and electrochemical impedance spectroscopy (EIS) were performed for devices based on P1 or P2. The effect of the additions of Li-TFSI and TBP to P1 and P2 was also researched. The results show that the additions of Li-TFSI and TBP can improve the hole conductivities of P1 and P2 and their charge transfer abilities. The P1 and P2 based devices with additives of Li-TFSI and TBP achieve 0.50% and 0.56% of PCE, respectively.
