Well-engineered buried interfaces play a pivotal role in achieving high-performance perovskite solar cells (PSCs). A superior buried interface involves controlled perovskite crystallization, efficient charge transfer across interfaces, and robust interfacial bonding. Here, a class of innovative additives, benzoyl sulfonyl molecules including 4-sulfobenzoic acid monopotassium salt (K-SBA), and 4-sulfamoylbenzoic acid (SBA) is introduced to tailer the SnO2/perovskite buried interface, aiming to meet these essential criteria. Among them, K-SBA performed better. The findings reveal that the functional groups of K-SBA establish interactions with both SnO2 and perovskite, leading to effective bilateral passivation and mitigation of interface stress. This results in the formation of a pore-free buried interface and high-quality perovskite films with substantial crystal sizes. Consequently, PSCs incorporating K-SBA exhibited a notable increase in efficiency, achieving 24.56% efficiency compared to the control device's 22.27%. Furthermore, these K-SBA-enhanced PSCs maintain 90% of their original efficiency even after 500 h of maximum power point tracking. This work provides valuable insights for further refinement and advancement of buried interfaces in PSCs.

用于高性能钙钛矿太阳能电池埋入界面双边钝化和晶体调节的苯甲酰磺酰分子
精心设计的埋入界面在实现高性能钙钛矿太阳能电池（PSC）方面发挥着关键作用。优异的埋入界面涉及受控的钙钛矿结晶、跨界面的高效电荷转移以及牢固的界面键合。这里引入了一类创新添加剂，苯甲酰磺酰分子，包括4-磺基苯甲酸单钾盐（K-SBA）和4-氨磺酰苯甲酸（SBA）来修饰SnO 2 /钙钛矿埋入界面，旨在满足这些基本标准。其中，K-SBA表现较好。研究结果表明，K-SBA 的官能团与 SnO 2 和钙钛矿建立相互作用，从而实现有效的双边钝化和界面应力减轻。这导致形成无孔埋入界面和具有较大晶体尺寸的高质量钙钛矿薄膜。因此，采用 K-SBA 的 PSC 的效率显着提高，达到 24.56% 的效率，而控制装置的效率为 22.27%。此外，即使在最大功率点跟踪 500 小时后，这些 K-SBA 增强型 PSC 仍能保持其原始效率的 90%。这项工作为进一步完善和改进 PSC 中埋入界面提供了宝贵的见解。
