A Versatile Bridging Molecule Managed the Buried SnO2/Perovskite Interface for Efficient and Stable Perovskite Solar Cells

layer, improve the crystallization of perovskite absorber, thus ultimately achieving a gratifying efficiency of 25.32% with negligible hysteresis. What's more, the optimized device delivers admirable stability sustaining over 90% of initial power conversion efficiency after being aged under continuous 85 °C heating stress with 40 ± 5% RH humidity for ≈600 and ≈1200 h under continuous 1-sun illumination, respectively.
