摘　　要：铅卤钙钛矿太阳能电池因其优良的光电转换效率以及相对低廉的制备成本而受到广泛关注。然而铅卤钙钛矿太阳能电池的长期稳定性限制了其商业化的进程。界面非辐射复合导致铅卤钙钛矿太阳能电池产生能量损失、影响器件稳定性,是造成器件性能恶化的主要原因。界面工程作为一种有效的策略被用于抑制界面非辐射复合,在制备高效稳定的铅卤钙钛矿太阳能电池方面取得了切实的成效。本文阐述了铅卤钙钛矿太阳能电池的工作原理以及界面上的非辐射复合过程,分析了界面非辐射复合产生的原因,总结了近期n-i-p正式结构铅卤钙钛矿太阳能电池中界面工程的研究进展,讨论了其作用机制。基于目前铅卤钙钛矿太阳能电池中的界面工程发展现状,对其未来的发展方向进行了展望。Lead halide perovskite solar cells have attracted extensive attention on account of their excellent photoelectric conversion efficiency and relatively low fabrication cost.However,the poor long-term stability becomes a barrier that hinders the commercialization of lead halide perovskite solar cells.It is reported that interfacial non-radiative recombination in lead halide perovskite solar cells is the main cause that leads to energy loss,affects device stability and then deteriorates the device performance.To solve this issue,interface engineering is applied as a valid strategy to suppress interfacial non-radiative recombination and fabricate efficient and stable lead halide perovskite solar cells,achieving tangible results.In this review,the working principle of lead halide perovskite solar cells and interfacial non-radiactive recombination process are explained in detail.The origin of interfacial non-radiative recombination is also analyzed,which highlights the important role of interface engineering for lead halide perovskite solar cells.Meanwhile,the recent research advances of interface engineering in lead halide perovskite solar cells with normal n-i-p structure are summarized with the discussion of the modification mechanism.What’s more,based on the development status of the interface engineering in lead halide perovskite solar cells,we prospect the development directions for the interface engineering in lead halide perovskite solar cells in the future.
