The rapid and continuous progress made in perovskite solar cell (PSC) technology has drawn considerable attention from the photovoltaic research community, and the application of perovskites in other electronic devices (such as photodetectors, light-emitting diodes, and batteries) has become imminent. Because of the diversity in device configurations, optimization of film deposition, and exploration of material systems, the power conversion efficiency (PCE) of PSCs has been certified to be as high as 25.2%, making this type of solar cells the fastest advancing technology until now. As demonstrated by researchers worldwide, controlling the morphology and defects in perovskite films is essential for attaining high-performance PSCs. In this regard, interface engineering has proven to be a very efficient way to address these issues, obtaining better charge collection efficiency, and reducing recombination losses. In this review, the interfacial modification between perovskite films and charge-transport layers (CTLs) as well as CTLs and electrodes of PSCs has been widely summarized. Grain boundary (GB) engineering and stress engineering are also included since they are closely related to the improvement in device performance and stability.
钙钛矿太阳能电池（PSC）技术取得的快速且持续的进展引起了光伏研究界的广泛关注，并且钙钛矿在其他电子器件（如光电探测器、发光二极管和电池）中的应用已迫在眉睫。由于器件结构的多样性、薄膜沉积的优化以及材料体系的探索，PSC的功率转换效率（PCE）已被证实高达25.2%，使这类太阳能电池成为迄今为止发展最快的技术。正如全球研究人员所表明的那样，控制钙钛矿薄膜的形貌和缺陷对于获得高性能PSC至关重要。在这方面，界面工程已被证明是解决这些问题、获得更好的电荷收集效率以及减少复合损失的一种非常有效的方法。在这篇综述中，已广泛总结了钙钛矿薄膜与电荷传输层（CTL）以及PSC的CTL与电极之间的界面修饰。还包括晶界（GB）工程和应力工程，因为它们与器件性能和稳定性的提高密切相关。
