N2 - It is challenging to improve the long-term stability of perovskite solar cells (PSCs) without sacrificing efficiency. The perovskite absorbers degrade from the film surface/interfaces, which follows entangled mechanisms that have not been fully revealed yet. Herein, we decouple and elaborate two distinctive pathways regarding film degradation based on FACsPbI3 perovskites. Moreover, a dual interfacial modification strategy has been developed for improving the material’s intrinsic stability, thus leading to the film degrading in a more retardant pathway. The corresponding PSCs achieve a stable power output efficiency of 23.75%. More importantly, the unencapsulated PSCs devices retain over 93% of their initial PCE after the maximum power point (MPP) tracking under the continuous 1-sun illumination and show significantly improved stability after aged under the thermal treatment or stored in ambient atmosphere for over 1500 hours without obvious PCE decay.
