Mechanisms of radiation degradation of solar cells based on organic-inorganic perovskites

The basic processes of perovskite radiation resistance are discussed for photo- and high-energy electron irradiation. It is shown that ionization of iodine ions and a staged mechanism of elastic scattering (upon intermediate scattering on light ions of an organic molecule) lead to the formation of a...

Description
Summary:The basic processes of perovskite radiation resistance are discussed for photo- and high-energy electron irradiation. It is shown that ionization of iodine ions and a staged mechanism of elastic scattering (upon intermediate scattering on light ions of an organic molecule) lead to the formation of a recombination center I i . The features of ionization degradation of interfaces with both planar and fractal structures are considered. A special type of fractality is identified, and its minimum possible level of photodegradation is predicted.
