Abstract

Hybrid organic-inorganic perovskite materials are of current interest as promising light-harvesting materials for photovoltaics. However, the main problem of their industrial implementation is the stability in various temperature and humidity conditions. The change in the crystal structure of hybrid perovskite thin films under ambient conditions was studied using X-ray diffraction. In particular, during degradation of the films, the formation of a monohydrate as an intermediate phase was detected. In addition, X-ray diffraction data indicated layer-by-layer degradation of the films.
