Interface Defects of Perovskite Solar Cells and Their Suppression Methods

中文摘要英文摘要

目前,绝大多数高效有机-无机卤化物钙钛矿(OIHP)太阳能电池都是由多晶钙钛矿薄膜构成,这些多晶薄膜表面或晶界往往含有大量的缺陷,将导致光生载流子发生非辐射复合,并诱导OIHP材料分解,从而使器件的光电转换效率(PCE)和稳定性降低.本综述分析了钙钛矿太阳能电池的缺陷类型及缺陷对钙钛矿太阳能电池(PSCs)性能的影响,详细介绍了通过钝化电极与传输层,或传输层与钙钛矿层间的界面缺陷以获得更高效率和高稳定性的钙钛矿太阳能电池方面的研究进展,展望了钝化分子的设计思路及钙钛矿光伏商业化应用所面临的挑战.

At present,most high-efficiency organic-inorganic halide perovskite(OIHP)solar cells are made of polycrystalline perovskite films,and the surface or grain boundaries of these polycrystalline films often contain a large number of defects.The defects in the OIHP film will lead to non-radiative recombination of photogenerated carriers and induce the decomposition of the OIHP material,resulting in a decrease in the power conversion efficiency(PCE)and stability of the device.In this review,the types of defects in perovskite solar cells and the effects of defects on the performance of perovskite solar cells(PSCs)were analyzed.The progress of passivation of interface defects between electrode and charge transport layer or between charge transport layer and perovskite layer to obtain higher efficiency and stability of perovskite solar cells is introduced in detail.The design ideas of passivation molecules and the challenges facing the commercial application of perovskite photovoltaics are prospected.
