  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 Ii. 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. By using the methodology of classical radiation physics, the Hoke
effect was also studied, as well as the synergetics of cooperative phenomena in
tandem systems. The principal channels for counteracting the radiation
degradation of solar cells based on hybrid perovskites have been revealed.
