In this work, incorporating donor-acceptor structured AIE molecule (TPE-TCF) into the perovskite precursor solution can improve the morphology of perovskite film and suppress nonradiative carrier recombination, leading to perovskite solar cells with reduced trap density and negligible hysteresis. The power conversion efficiency (PCE) of TPE-TCF-treated PSCs achieved a remarkably enhanced from 15.63 to 19.66 % with high charge transport and defects passivation under air condition without a glovebox.

当聚集诱导发射遇到钙钛矿时：钙钛矿太阳能电池环境制造的高效缺陷钝化和电荷转移

在这项工作中，将供体-受体结构的 AIE 分子 (TPE-TCF) 加入钙钛矿前驱体溶液中可以改善钙钛矿薄膜的形态并抑制非辐射载流子复合，从而使钙钛矿太阳能电池具有降低的陷阱密度和可忽略的滞后现象。在没有手套箱的情况下，TPE-TCF 处理的 PSC 的功率转换效率 (PCE) 从 15.63% 显着提高到 19.66%，具有高电荷传输和缺陷钝化。
