The method of obtaining ZnO thin films for use as an electron transport layer was optimized. The influence of aluminum, gallium, and bismuth impurities on the morphological, optical, and electronic properties of zinc oxide thin films was investigated, in particular, the relationship between the amount of dopant and the electronic structure of ZnO thin films was established. The morphological features of the synthesized materials - components of solar cells based on perovskites have been determined. The change in the width of their of the band gap. It was found that the design of the structure of calcium apatites by isomorphic substitutions in the cationic and anionic sublattices makes it possible to control the width of the energy band gap. The dependence of the thermal stability of hybrid organic-inorganic perovskites CH3NH3PbX3 (X= Cl, Br, I) on the nature of the halogen atom was studied and the mechanisms for controlling the thermal stability of perovskites by varying the halogen atom in their structure were described. The ZnO-apatite encapsulating layer was developed in the form of conductive composite films. The structural and morphological features of composite films with different concentrations of apatite were comprehensively investigated. The peculiarities of redistribution of electronic charge during perovskite degradation and formation of the ZnO/apatite interface have been established. It was determined that the ZnO-apatite encapsulating layer with a ratio of components of 3:1 has the most optimal characteristics. Product Description popup.authors Ivanov Oleksii V.
