摘要
钙钛矿太阳能电池(Perovskite solar cells, PSCs)因其迅速发展的能量转换效率而备受关注.提高PSCs性能特别是稳定性仍是人们研究的热点.金属有机框架(Metal-organic frameworks, MOFs)因其高比表面积的孔隙结构、功能结构可设计性强等优点,被应用在钙钛矿太阳能电池中,表现出优异的性能.总结了MOFs在调控钙钛矿的结晶、钝化缺陷、提高载流子的迁移率和其他功能方面的研究,并提出了目前PSCs研究中MOFs存在的卡脖子问题及可优化的方向,对进一步提高MOFs在增强PSCs器件的效率和稳定性方面的价值具有重要意义.
Perovskite solar cells(PSCs) have attracted wide attention for their dramatically improved energy conversion efficiency.Improving the performance of PSCs, especially its stability, is still a research hotspot.Due to their pore structure with large specific surface area and strong designability of functional structure, metal-organic frameworks(MOFs) have been used in perovskite solar cells and have shown excellent performance.This article summarizes the research of MOFs in regulating perovskite crystallization, passivating defects, improving the carrier mobility and other functions, points out the bottleneck problem of MOFs in PSCs research, and puts forward the direction of optimization, which is of great significance to further promote the value of MOFs in improving the efficiency and stability of PSCs devices.
