Abstract Upscaling the perovskite solar cell (PSC) while avoiding losses in power conversion efficiency presents a substantial challenge, especially when transitioning from ≤1 cm 2 cells to ≥10 modules. In addition fabrication of key functional layers, scalable technologies for surface passivation, considered indispensable achieving high‐performance PSCs, are urgently required. However, studies on this topic remain limited. study, an industry‐ready slot‐die coating method effective passivation films as practical alternative is developed spin‐coating procedures commonly used research. The conditions and molecular structure agent systematically optimized achieve high‐quality film morphology substantially suppress interface recombination. 2‐chloro‐5‐(trifluoromethyl)‐phenylammonium bromide exhibited best results, improving open‐circuit voltage subcells module by 80 ± 4 72 10 mV, respectively. Correspondingly, larger‐area (active area: ) modules sustained highest 21.9% under simulated 1‐sun irradiation. encapsulated devices retained 94% their initial performances after 750 h continuous operation. proposed surface‐passivation technology compatible with high‐throughput processes employable large‐scale PSC fabrication.
