Abstract Perovskite solar cells (PSCs) have shown remarkable progress in laboratory‐scale devices, but their scalability to large‐area perovskite modules (PSMs) remains challenging due significant performance loss. Here, a multi‐site passivation strategy is reported by employing Bis(2,5‐dioxopyrrolidin‐1‐yl) 2,2′‐(propane‐2,2‐diylbis(sulfanediyl)) diacetate (TK‐NHS) as an interfacial modifier address the critical issues of interface recombination and stability both PSCs PSMs. TK‐NHS effectively inactivates common defects, modifying surface films through synergistical interactions. Additionally, stable dipole layer formed at optimizes energy level alignment, facilitating efficient electron extraction transport. The resulting film exhibited smoother more homogeneous surface, thus improving contact reducing nonradiative recombination. Consequently, TK‐NHS‐treated achieved champion power conversion efficiency (PCE) 26.16%, with significantly improved open‐circuit voltage ( V oc ) 1.188 fill factor (FF) 85.3%. scalable potential this has been verified corresponding PSMs, delivering impressive PCE 22.25%. Notably, devices exceptional operational stability, retaining 91.4% 90% initial after 1000 800 h continuous illumination, respectively. Thereby advancing scaled‐up production modules.
