Three new hole-transporting materials (HTMs), composed of N³,N⁶-bis(di-4-anisylamino)-9H-carbazole and anthracene moieties, have been developed for perovskite solar cell (PSC) application. Two of the new HTMs have better hole mobility and hole-extraction ability compared to spiro-OMeTAD. Accordingly, the best PSC based on mixed ion perovskite of Cs_0.05FA_0.79MA_0.16PbI_2.49Br_0.51 and doped HTMs has better power conversion efficiency (18.65%) than the corresponding PSC based on doped spiro-OMeTAD (17.90%). Moreover, the PSCs based on these HTMs have negligible hysteresis and good temporal stability.

双（二苯胺）拴在一起的咔唑基蒽衍生物作为稳定和高性能钙钛矿太阳能电池的空穴传输材料

已经开发出三种由N ³，N ^6-双（二-4-茴香基氨基）-9 H-咔唑和蒽部分组成的新型空穴传输材料（HTM），用于钙钛矿太阳能电池（PSC）应用。与spiro-OMeTAD相比，其中两个新的HTM具有更好的空穴迁移率和空穴提取能力。因此，基于Cs _0.05 FA _0.79 MA _0.16 PbI _2.49 Br _0.51的混合离子钙钛矿和掺杂HTM的最佳PSC具有比基于掺杂螺-OMeTAD的相应PSC（17.90％）更好的功率转换效率（18.65％）。此外，基于这些HTM的PSC具有可忽略的滞后性和良好的时间稳定性。
