This study demonstrated the feasibility of creating solid-state X-ray detectors with reduced human exposure to radiation doses based on perovskite CH3NH3PbBr3. Using voltammetry and impedance spectroscopy, investigated the effects of visible and 0.15 nm X-ray photons on the electrical structure (equivalent circuit parameters), diffusion time, and charge carrier mobility of the planar organic and inorganic perovskite. The results were interpreted within the diffusion approximation of transport theory in the low-frequency range of alternating electric field oscillations. It was shown that an electric field (direct bias current) changes the charge carrier concentration and influences the conditions of their transport by altering the diffusion time (the lifetime of charges during their transport). The identified combined radiation effects reveal a novel form of synergistic interaction, whereby ionization of atomic chains at successive stages promotes defect formation, while subsequent shock-wave propagation and the recombination of thermalized electrons at defect sites contribute to partial defect healing and enhancement of material properties relative to the initial state.
