New heterocyclic quinoid-based hole transporting materials (HTMs) with a rigid quinoid core [3,6-di(2H-imidazol-2-ylidene)cyclohexa-1,4-diene] have been synthesized. The new HTMs have good hole mobility (>10 cm V s ) and very intense absorption in the near-infrared region extending to >800 nm. High performance perovskite solar cells can be fabricated using these HTMs without dopant. The best cell efficiency under simulated AM 1.5 G illumination reaches 12.22 %, which is comparable with that (12.58 %) using doped 2,2',7,7'-tetrakis-(N,N-di-4-methoxyphenylamino)-9,9'-spirobifluorene (spiro-OMeTAD) as the HTM.
已合成出具有刚性醌核[3,6-二(2H-咪唑-2-亚基)环己-1,4-二烯]的新型杂环醌基空穴传输材料(HTMs)。这些新型HTMs具有良好的空穴迁移率(>10 cm² V⁻¹ s⁻¹)，并且在延伸至>800 nm的近红外区域有非常强烈的吸收。使用这些无掺杂剂的HTMs可以制备出高性能的钙钛矿太阳能电池。在模拟AM 1.5 G光照下，最佳电池效率达到12.22%，这与使用掺杂的2,2',7,7'-四-(N,N-二-4-甲氧基苯基氨基)-9,9'-螺二芴(spiro-OMeTAD)作为HTM时的效率(12.58%)相当。
