We report a novel electron-rich molecule based on 3,4-ethylenedioxythiophene (H101). When used as the hole-transporting layer in a perovskite-based solar cell, the power-conversion efficiency reached 13.8 % under AM 1.5G solar simulation. This result is comparable with that obtained using the well-known hole transporting material 2,2',7,7'-tetrakis(N,N-di-p-methoxyphenylamine)-9,9'-spirobifluorene (spiro-OMeTAD). This is the first heterocycle-containing material achieving >10 % efficiency in such devices, and has great potential to replace the expensive spiro-OMeTAD given its much simpler and cheaper synthesis.
我们报告了一种基于 3,4-亚乙基二氧噻吩（H101）的新型富电子分子。当将其用作基于钙钛矿的太阳能电池中的空穴传输层时，在 AM 1.5G 太阳模拟下，其功率转换效率达到了 13.8%。这一结果可与使用著名的空穴传输材料 2,2',7,7'-四[N,N-二（对甲氧基苯基）氨基]-9,9'-螺二芴（spiro-OMeTAD）获得的结果相媲美。这是首例在这类器件中效率超过 10%的含杂环材料，鉴于其合成更为简单、廉价，有望替代昂贵的 spiro-OMeTAD。
