我们设计并合成了三种新型的苯并二噻唑类空穴传输材料（HTMs），分别命名为BTT-TPA，BTT-OMe和BTT-Me。采用1H、13 C NMR、FTIR、元素分析、UV-维斯分光光度计和循环伏安法对这些新型HTMs进行了表征。在钙钛矿太阳能电池（PSC）中成功地评估了这些HTM的光伏性能。因此，基于BTT-TPA、BTT-MeandBTT-OMeHTMs的PSC分别显示出12.81 mA cm−2、11.87 mA cm−2、13.85 mA cm−2的Jsc，0.88 V、0.83 V、0.87 V的Voc，0.62、0.63、0.63的FF以及（η）6.99%、6.20%和7.44%的总功率转换效率。 简单的合成路线和纯化技术提供了这些HTM作为未来PSC开发的可行性。
We have designed and synthesized a family of three novel benzodithiazole‐based hole‐transporting materials (HTMs) named asBTT‐TPA, BTT‐OMeandBTT‐Me. These new HTMs are characterized by using1H,13C NMR, FTIR, elemental analysis, UV‐Vis spectrophotometer, and cyclic voltammetry. The photovoltaic performances of these HTMs were successfully evaluated in perovskite solar cells (PSCs). Consequently, the PSCs based onBTT‐TPA,BTT‐MeandBTT‐OMeHTMs showed Jscof 12.81 mA cm−2, 11.87 mA cm−2, 13.85 mA cm−2, Vocof 0.88 V, 0.83 V, 0.87 V, a FF of 0.62, 0.63, 0.63 and the overall power conversion efficiency of (η) 6.99%, 6.20% and 7.44%, respectively. The easy synthetic route and purification technique provides the viability of these HTMs as future PSCs development.
