Perovskite solar cells are among the most promising photovoltaic technologies in academia and have the potential to become commercially available in the near future. However, there are still a few unresolved issues regarding device lifetime and fabrication cost of perovskite solar cells in order to be competitive with existing technologies. Herein, we report small organic molecules with introduced vinyl groups as hole transporting materials, which are capable of undergoing thermal polymerization, forming solvent-resistant 3D networks. Novel compounds have been synthesized from relatively inexpensive starting materials and their purification is less time-consuming when compared to polymers; therefore this type of hole transporter can be a promising alternative to lower the manufacturing cost of perovskite solar cells.
钙钛矿太阳能电池是学术界最具前景的光伏技术之一，并且有潜力在不久的将来实现商业化。然而，为了与现有技术竞争，钙钛矿太阳能电池在器件寿命和制造成本方面仍存在一些未解决的问题。在此，我们报道了引入乙烯基的小分子作为空穴传输材料，它们能够进行热聚合，形成耐溶剂的三维网络。新型化合物由相对廉价的起始材料合成，与聚合物相比，其纯化耗时更少；因此，这种类型的空穴传输体有望成为降低钙钛矿太阳能电池制造成本的替代方案。
