We investigate degradation mechanisms of perovskite solar cells under different atmospheres via in-situ grazing-incidence X-ray scattering methods. We reveal that the atmosphere has a significant influence on degradation mechanisms for materials. This results in the degradation of the performances of the relative perovskite solar cells. Compared with the performance evolution of perovskite solar cells under vacuum, they show better stability under nitrogen.
