Self‐assembled monolayers (SAMs), owing to their unique and versatile abilities to manipulate chemical and physical interfacial properties, have emerged as powerful nanomaterials for improving the performance of perovskite solar cells (PSCs). Indeed, in the last six years, a collection of studies has shown that the application of SAMs to PSCs boosts the performance of devices compared to the pristine PSCs. This review describes recent studies that demonstrate the direct advantages of SAM‐based interfacial engineering to power conversion efficiency (PCE) of PSCs. This review includes 1) a brief introduction on SAMs as interfacial engineering nanomaterials; 2) a thorough survey of molecules used in SAM‐engineered PSCs and analysis of chemical structures; 3) an extensive discussion on how SAMs affect the morphology of perovskite film and the electronic function of devices; and 4) a comprehensive summary of various types of approaches for producing SAM‐engineered PSCs. This review provides an insightful perspective to stimulate new ideas and innovation in the development of PSCs for the next‐generation photovoltaics and beyond.

自组装单层作为钙钛矿太阳能电池中的界面工程纳米材料

自组装单分子膜（SAMs）由于其独特的通用性来控制化学和物理界面特性，已成为增强钙钛矿太阳能电池（PSC）性能的强大纳米材料。实际上，在过去的六年中，大量研究表明，与原始PSC相比，将SAM用于PSC可以提高设备的性能。这篇综述描述了最近的研究，这些研究证明了基于SAM的界面工程对PSC的功率转换效率（PCE）的直接优势。这篇综述包括：1）SAMs作为界面工程纳米材料的简要介绍；2）对SAM工程的PSC中使用的分子进行彻底的调查，并对化学结构进行分析；3）关于SAM如何影响钙钛矿薄膜形态和器件电子功能的广泛讨论；和4）关于生产SAM工程的PSC的各种方法的综合总结。这篇综述提供了一个有见地的观点，可以激发下一代光伏及其后续产品的PSC开发中的新思路和创新。
