Two novel and simple donor-π-bridge-donor (D-π-D) hole-transporting materials (HTMs) containing two units of the p-methoxytriphenylamine (TPA) electron donor group covalently bridged by means of the 3,4-dimethoxyselenophene spacer through single and triple bonds are reported. The optoelectronic and thermal properties of the new selenium-containing HTMs have been determined using standard experimental techniques and theoretical density functional theory (DFT) calculations. The selenium-based HTMs have been incorporated in mesoporous perovskite solar cells (PSCs) in combination with the triple-cation perovskite [(FAPbI3)0.87(MAPbBr3)0.13]0.92 [CsPbI3]0.08. Limited values of power conversion efficiencies, up to 13.4 %, in comparison with the archetype spiro-OMeTAD (17.8 %), were obtained. The reduced efficiencies showed by the new HTMs are attributed to their poor film-forming ability, which constrains their photovoltaic performance due to the appearance of structural defects (pinholes).

用于钙钛矿太阳能电池的硒吩基空穴传输材料
两种新型简单的供体-π-桥-供体（D-π-D）空穴传输材料（HTM），含有两个通过3,4-二甲氧基硒吩共价桥联的对甲氧基三苯胺（TPA）电子供体基团单元报道了通过单键和三键的间隔基。新型含硒 HTM 的光电和热性能已使用标准实验技术和理论密度泛函理论 (DFT) 计算确定。硒基 HTM 已与三重阳离子钙钛矿 [(FAPbI 3 ) 0.87 (MAPbBr 3 ) 0.13 ] 0.92 [CsPbI 3 ] 0.08结合并入介孔钙钛矿太阳能电池（PSC）中。与原型 spiro-OMeTAD (17.8%) 相比，获得了高达 13.4% 的有限功率转换效率值。新型HTM效率降低的原因在于其成膜能力差，结构缺陷（针孔）的出现限制了其光伏性能。
