Non-fullerene ETMs are emerging as a hot topic in the field of PSCs due to the inherent shortcomings of fullerene derivatives. Herein, the potential of SubPcs as ETMs in PSCs has been evaluated. To this end, ETMs based on two SubPcs (with chlorine or fluorine at the axial position) have been incorporated in PSCs, where the perovskite is deposited by either solution processing (CsFAMAPbIBr) or thermal evaporation (MAPI). The device performance and morphology of these devices are analyzed in depth using several techniques, and the interfacial effects induced by the SubPcs are studied using PL and TR-PL. In all cases, the SubPc with axial chlorine led to higher efficiencies. Thus, a maximum PCE of 10.8% was achieved with the champion device using a SubPc/C60 double-layer ETM.

用于钙钛矿太阳能电池的亚酞菁基电子传输材料
由于富勒烯衍生物的固有缺点,非富勒烯 ETM 正在成为 PSC 领域的热门话题。在此,已经评估了 SubPcs 作为 PSC 中 ETM 的潜力。为此,基于两个 SubPcs(在轴向位置带有氯或氟)的 ETM 已被纳入 PSC,其中钙钛矿通过溶液处理 (CsFAMAPbIBr) 或热蒸发 (MAPI) 沉积。使用多种技术对这些器件的器件性能和形态进行了深入分析,并使用 PL 和 TR-PL 研究了 SubPcs 引起的界面效应。在所有情况下,带有轴向氯的 SubPc 导致更高的效率。因此,使用SubPc/C 60双层 ETM的冠军设备实现了 10.8% 的最大 PCE 。
