A low-cost carbazole-based small-molecule material, 1,3,6,8-tetra(N,N-p-dimethoxyphenylamino)-9-ethylcarbazole, was designed and synthesized through a facile three-step synthetic route. The material was characterized and applied as a hole-transport material (HTM) for low-temperature-processed planar perovskite solar cells (PSCs). Devices based on this new HTM exhibit a high power-conversion efficiency of 17.8 % that is comparable to that of PSCs based on the costly 2,2',7,7'-tetrakis[N,N-di(4-methoxyphenyl)amino]-9,9'-spirobifluorene (Spiro-OMeTAD) (18.6 %) .
一种低成本咔唑基小分子材料，1,3,6,8-四（N,N-二对甲氧基苯基氨基）-9-乙基咔唑，通过简便的三步合成路线设计和合成。对材料进行了表征，并将其用作低温处理的平面钙钛矿太阳能电池（PSCs）的空穴传输材料（HTM）。基于这种新型 HTM 的器件表现出 17.8%的高光能量转换效率，与基于昂贵的 2,2',7,7'-四[N,N-二（4-甲氧基苯基）氨基]-9,9'-螺二芴（Spiro-OMeTAD）（18.6%）的 PSCs 相当。
