On the degradation mechanism of functioning solar cells based on organic-inorganic perovskites

Abstract

This paper presents the first attempt to build a model and detect the degradation mechanism of organic-inorganic photovoltaic solar cells based on perovskites. The cross section of the process of the formation of a close Frenkel pair in the sublattice of iodine is obtained and its annealing channels are found. It is concluded that there is a nonmonotonic dependence of the stationary number of defects on the intensity of solar radiation, which allows one to analyze the properties of the radiation resistance of a device to ionizing radiation.
