Here we report for the first time an efficient fullerene-based compound, FU7, able to act as hole-transporting material (HTM) and electron blocking contact. It has been applied on perovskite solar cells (PSCs), obtaining 0.81 times the efficiency of PSCs with the standard HTM, spiro-OMeTAD, with the additional advantage that this performance is reached without any additive introduced in the HTM layer. Moreover, as a proof of concept, we have described for the first time efficient PSCs in which both selective contacts are fullerene derivatives, to obtain unprecedented "fullerene sandwich" PSCs.
在这里，我们首次报道了一种有效的富勒烯基化合物 FU7，它能够作为空穴传输材料（HTM）和电子阻挡接触。我们将其应用于钙钛矿太阳能电池（PSCs）中，获得了比使用标准 HTM 即 spiro-OMeTAD 的 PSCs 效率提高 0.81 倍的结果，而且具有无需在 HTM 层中添加任何添加剂的额外优势。此外，作为概念验证，我们首次描述了在其中两个选择性接触均为富勒烯衍生物的高效 PSCs，以获得前所未有的“富勒烯夹层”PSC。
