The electrical and optical properties of the hole transport layer (HTL) are critical for organic and halide perovskite solar cell (OSC and PSC, respectively) performance. In this work, we studied the effect of Mg doping on CuCrO (CCO) nanoparticles and their performance as HTLs in OSCs and PSCs. CCO and Mg doped CCO (Mg:CCO) nanoparticles were hydrothermally synthesized. The nanoparticles were characterized by various experimental techniques to study the effect of Mg doping on structural, chemical, morphological, optical, and electronic properties of CCO. We found that Mg doping increases work function and decreases particle size. We demonstrate CCO and Mg:CCO as efficient HTLs in a variety of OSCs, including the first demonstration of a non-fullerene acceptor bulk heterojunction, and CHNHPbI PSCs. A small improvement of average short-circuit current density with Mg doping was found in all systems.
空穴传输层(HTL)的电学和光学性质对于有机太阳能电池和卤化物钙钛矿太阳能电池(分别为OSC和PSC)的性能至关重要。在本工作中,我们研究了Mg掺杂对CuCrO(CCO)纳米颗粒的影响及其在OSC和PSC中作为HTL的性能。通过水热法合成了CCO和Mg掺杂的CCO(Mg:CCO)纳米颗粒。采用各种实验技术对纳米颗粒进行表征,以研究Mg掺杂对CCO的结构、化学、形态、光学和电子性质的影响。我们发现Mg掺杂会增加功函数并减小粒径。我们证明了CCO和Mg:CCO在各种OSC中是有效的HTL,包括首次展示的非富勒烯受体体异质结以及CHNHPbI PSC。在所有系统中均发现,Mg掺杂使平均短路电流密度有小幅提高。
