Seasonal Effects on Outdoor Stability of Perovskite Solar Cells

Abstract: The critical challenge for the commercialization of perovskite solar cells (PSCs) is their operational stability. PSCs’ outdoor operation exposes the cells to a combination of stress factors that are difficult to reproduce by indoor testing due to diurnal and seasonal variations. This highlights the need for outdoor testing under operational conditions. The effect of climate conditions on outdoor operational lifetime/degradation of n‐i‐p PSCs is systematically studied herein. Their lifetime indicators are determined in different seasons, and correlated with the outdoor irradiance and temperatures measured simultaneously. Based on this outdoor measurement analysis and indoor light cycling stability tests, it is suggested that ambient temperatures induce a more significant effect than the irradiance on the PSC's lifetime/degradation. The study also suggests different roles played by the temperatures during the diurnal light versus dark periods: the day/light time maximum temperatures have a more significant effect on the long‐term degradation. In contrast, minimum temperatures during the night/dark cycles significantly affected the diurnal reversible degradation and the initial fast degradation. The results show that the commonly used lifetime indicators T80 and T50 are climate‐dependent, and their use for comparative purposes is valid only if measured in similar climatic conditions.
