英文摘要Layered Ruddlesden-Popper (RP) perovskites have good moisture- and photostability. However, thermal stability of the RP perovskites is still a challenge. In this work, through a joint theoretical and experimental study, we report an intralayer A-site compositional engineering strategy to enhance the thermal stability of the RP perovskite solar cells. The triple-A-site-cation BA(2)(MA(0.76) FA(0.19)Cs(0.05)) Pb4I13 (labeled as T-RP) cells retain 80% of the initial efficiency after being stressed at a constant temperature of 85 degrees C for over 1400 h in the dark, which is a significant enhancement as compared to the FA-free or Cs-free double-A-sitecation reference devices. Enhanced stability is attributed to improved structural stability, film quality with larger and more compact micrometer grains, and lower trap densities of the T-RP, as compared to the double-A-site-cation RP perovskites. When appropriate excess PbI2 is introduced in the T-RP layer, a power conversion efficiency of perovskite solar cells with high thermal stability. 15.58% is obtained for RP perovskite solar cells with high thermal stability.
