The development of the simple synthesis schemes of organic semiconductors can have an important contribution to the advancement of related technologies. In particular, one of the fields where the high price of the hole‐transporting materials may become an obstacle toward successful commercialization is perovskite solar cells. Herein, enamine‐based materials that are capable of undergoing cross‐linking due to the presence of two vinyl groups are synthesized. It is shown that new compounds can be thermally polymerized, making the films resistant to organic solvents. This can allow the use of a wet‐coating process for the deposition of the perovskite absorber film, without the need for orthogonal solvents. Cross‐linked films are used in perovskite solar cells, and, upon optimization of the film thickness, the highest power conversion efficiency of 18.1% is demonstrated.

钙钛矿太阳能电池的基于烯胺的可交联空穴传输材料

有机半导体简单合成方案的发展可以为相关技术的发展做出重要贡献。特别是，钙钛矿型太阳能电池是空穴传输材料高昂价格可能成为成功商业化的障碍的领域之一。本文合成了由于存在两个乙烯基而能够发生交联的烯胺基材料。结果表明，新化合物可以进行热聚合，从而使该膜具有抗有机溶剂的能力。这可以允许使用湿涂工艺来沉积钙钛矿吸收膜，而无需正交溶剂。交联膜用于钙钛矿太阳能电池，并且通过优化膜厚度，可以达到18的最高功率转换效率。
