Hybrid organic-inorganic perovskite solar cells have recently emerged as one of the most promising low-cost photovoltaic technologies. The remarkable progress of perovskite photovoltaics is closely related to advances in interfacial engineering and development of charge selective interlayers. Herein, we present the synthesis and characterization of a fused azapolyheteroaromatic small molecule, namely anthradi-7-azaindole (ADAI), with outstanding performance as a hole-transporting layer in perovskite solar cells with inverted architecture. Its molecular arrangement, induced by hydrogen-bond-directed self-assembly, favors a suitable morphology of the perovskite layer, reducing the effects of recombination as revealed by light intensity dependence, photoluminescence, and electroluminescence studies.
有机-无机杂化钙钛矿太阳能电池最近已成为最有前途的低成本光伏技术之一。钙钛矿光伏的显著进展与界面工程的进步和电荷选择性中间层的开发密切相关。在此，我们展示了一种稠合氮杂多芳族小分子，即蒽并-7-氮杂吲哚（ADAI）的合成与表征，它作为倒置结构钙钛矿太阳能电池中的空穴传输层具有出色的性能。由氢键导向的自组装诱导的分子排列有利于钙钛矿层形成合适的形态，如光强依赖性、光致发光和电致发光研究所揭示的那样，减少了复合效应。
