Buried interface in perovskite solar cells (PSCs) is a critical determination for the performance and stability because it dominates crystallization of layer, non-radiative recombination, ion migration at interfaces. Herein, novel versatile modifier, potassium sucrose octasulfate (K8SOS) which rich sulfonic groups ions, introduced bridging buried SnO2 interface, to improve interfacial states further device performance. It found that K8SOS serves as bridge can not only passivate defects through multi-site strengthening chemical binding, thus effectively inhibiting non-radiation recombination suppressing migration, but also optimize surface state absorber, ultimately achieving gratifying efficiency 25.32% with negligible hysteresis. What's more, optimized delivers admirable sustaining over 90% initial power conversion after being aged under continuous 85 °C heating stress 40 ± 5% RH humidity ≈600 ≈1200 h 1-sun illumination, respectively.
