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
A-咔唑低成本的小分子材料,1,3,6,8-四(Ñ,ñ - p -dimethoxyphenylamino)-9-乙基咔唑,设计并合成通过容易的三步合成路线。对该材料进行了表征,并作为空穴传输材料(HTM)应用于低温处理的平面钙钛矿太阳能电池(PSC)。基于这种新型HTM的设备展现出17.8%的高功率转换效率,与基于昂贵的2,2',7,7'-四[ N,N-二(4-甲氧基苯基)氨基的PSC的功率转换效率相当] ‐9,9'‐螺二芴(Spiro‐OMeTAD)(18.6%)。
