It is highly desirable to develop novel n-type organic small molecules as an efficient electron-transport layer (ETL) for the replacement of PCBM to obtain high-performance metal-oxide-free, solution-processed inverted perovskite solar cells (PSCs) because this type of solar cells with a low-temperature and solution-based process would make their fabrication more feasible and practical. In this research, the new azaacene QCAPZ has been synthesized and employed as non-fullerene ETL material for inverted PSCs through a solution-based process without the need for additional dopants or additives. The as-fabricated inverted PSCs show a power conversion efficiency up to 10.26 %. Our results clearly suggest that larger azaacenes could be promising electron-transport materials to achieve high-performance solution-processed inverted PSCs.
开发新型n型有机小分子作为高效电子传输层（ETL）以替代PCBM来获得高性能的无金属氧化物、溶液处理的倒置钙钛矿太阳能电池（PSC）是非常可取的，因为这种具有低温和基于溶液工艺的太阳能电池将使其制造更加可行和实用。在本研究中，新型氮杂并苯QCAPZ已被合成，并通过基于溶液的工艺用作倒置PSC的非富勒烯ETL材料，无需额外的掺杂剂或添加剂。所制备的倒置PSC显示出高达10.26%的功率转换效率。我们的结果清楚地表明，更大的氮杂并苯可能是实现高性能溶液处理倒置PSC的有前途的电子传输材料。
