摘要：
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.
