Self-assembled monolayers (SAMs) have been a game-changer for perovskite solar cells (PSCs), significantly boosting their power conversion efficiency (PCE) to 27% in recent years. This breakthrough has garnered unprecedented attention, leading to significant advancements in the design and synthesis of SAM molecules (SAMols). Additionally, SAMs hold significant promise in addressing the lifetime of PSCs and facilitating their commercialization in terms of diversity, flexibility, and multifunctionality. To date, despite the development of numerous types of SAMols, challenges remain in designing and synthesizing optimal SAMols and achieving ultrastable devices that maintain outstanding PCEs. In this review, we systematically present recent advances in the design of SAMols, focusing on representative examples that have been employed in PSCs. Subsequently, a comprehensive overview of various synthetic pathways for these SAMols is provided for screening the most suitable synthesis method for target SAMols. Finally, challenges and potential opportunities for PSCs applications are highlighted.
自组装单分子层（SAMs）已成为钙钛矿太阳能电池（PSCs）的一个变革因素，近年来显著提高了其功率转换效率（PCE），达到27%。这一突破引起了前所未有的关注，推动了SAM分子（SAMols）设计与合成的重大进展。此外，SAMs在解决PSCs的寿命问题以及在多样性、灵活性和多功能性方面促进其商业化方面具有巨大潜力。迄今为止，尽管已开发出多种类型的SAMols，但在设计和合成最佳SAMols以及实现保持出色PCE的超稳定器件方面仍存在挑战。在本综述中，我们系统地介绍了SAMols设计的最新进展，重点关注PSCs中使用的代表性实例。随后，提供了这些SAMols各种合成途径的全面概述，以筛选出最适合目标SAMols的合成方法。最后，强调了PSCs应用面临的挑战和潜在机遇。
