Organic thermally-activated delayed fluorescence (TADF) materials have been widely applied in organic optoelectronics, biological oxygen sensing, fluorescence probes, and imaging. Inspired by sulfonyldibenzene-based TADF materials with considerable charge transport abilities and distorted structures, we design and synthesize three sulfonyldibenzene-based molecules (CS-01, CS-02, and CS-03) as hole transport materials (HTMs) for perovskite solar cells (PSCs). The CS series HTMs are endowed with excellent thermal stability, good solubility, and suitable energy level matched with perovskite material. As a result, the CS-01-based PSC devices deliver an impressive power conversion efficiency (PCE) of 19.94% and excellent thermal stability.

高效钙钛矿太阳能电池的不对称基于磺酰基二苯的空穴传输材料：有机热激活延迟荧光分子的启发。

有机热激活延迟荧光（TADF）材料已广泛应用于有机光电，生物氧传感，荧光探针和成像。受具有大量电荷传输能力和扭曲结构的基于磺酰二苯的TADF材料的启发，我们设计和合成了三种基于磺酰二苯的分子（CS-01，CS-02和CS-03）作为钙钛矿太阳能电池的空穴传输材料（HTM）。 （PSC）。所述CS系列HTMS被赋予了优异的热稳定性，良好的溶解性，并用钙钛矿材料匹配合适的能量水平。结果，CS-01基于PSC的器件可实现19.94％的出色功率转换效率（PCE）和出色的热稳定性。
