钙钛矿太阳能电池作为一个研究热点，显示了界面控制的必要性。在本研究中，在钙钛矿/空穴输运材料界面上自组装了一层绝缘的烷基链层，成功地展示了双重功能：同时阻止电子复合和抵抗水分。提高了太阳能转换效率，提高了装置的稳定性。
Perovskite solar cells as a hot research topic show the necessity of controlling the interface. In this work, an insulating alkyl chain layer is self-assembled at the perovskite/hole transport material interface, which successfully exhibits a dual function: blocking electron recombination and resisting moisture at the same time. Improved solar energy conversion efficiency and stability of the device are both achieved.
