Rapid progress in the domain of perovskite solar cells (PSCs) has boosted the power conversion efficiency (PCE) of such cells to 25.2%. However, the long‐term stability of a high‐performance PSCs is still the foremost concern that hinders its practical application. The interfaces are considered as the key part that determines the overall device performance and longevity. These interfaces include the intralayer grain boundaries (GBs) inside the perovskites, the interface between perovskites with electron/hole transport layer (ETL/HTL), and the interface of ETL/HTL with top/down contacts. To acquire a deep and detailed understanding of the impacts of interfacial properties, herein, a concise overview of recent interfacial engineering strategies with the aim of minimizing traps, promoting carrier extraction, and improving stability are summarized.

高性能，稳定钙钛矿太阳能电池接口工程的最新进展

钙钛矿太阳能电池（PSC）领域的快速发展已将此类电池的功率转换效率（PCE）提高到25.2％。但是，高性能PSC的长期稳定性仍然是阻碍其实际应用的首要问题。接口被认为是决定整体设备性能和寿命的关键部分。这些界面包括钙钛矿内部的层内晶界（GBs），钙钛矿与电子/空穴传输层（ETL / HTL）之间的界面以及ETL / HTL与上下接触的界面。为了获得对界面性质的影响的深入和详细的理解，在本文中，总结了对最近的界面工程策略的简要概述，其目的是使陷阱最小化，促进载流子提取和提高稳定性。
