This paper is devoted to interpretation of the research of a hybrid metalorganic perovskite film of the methylammonium-Pb-halogen3 type modified with detonation-synthesized nanodiamonds. The most striking of these results is the ability of the film to partially restore their differential conductivity G after a significant initial decrease during the periods of several to tens of days. The interpretation is based on modeling the rather complex structure of fields generated by functional groups at the periphery of the nanodiamond particles, which reach values on the order of interatomic fields. Keywords: halide perovskites, nanodiamonds, detonation synthesis, differential conductivity, quantum chemical modeling.
