The aim of the project is the development of physical and chemical bases of technology for the nanostructured zinc oxide arrays, and also SnS and Cu2ZnSnS4 films with controlled structural characteristics and electrical properties. Moreover, the purpose of the project includes the development on the base of new structural and technological solutions of QD-sensitized hybrid solar cells (SC), antireflective coatings for SC and selective coatings for thermal collectors. Methods of research are comprehensive analysis of technological modes, structural, optical and electrical properties of the nanostructured zinc oxide layers as well as SnS and Cu2ZnSnS4 films. The main scientific and technical results are the following. Physical and chemical basics of the laboratory technology for the creation of ZnO, SnS and Cu2ZnSnS4 nanostructured functional thin layers have been developed. Physical and chemical principles of the influence of the pulsed electrodeposition mode on the crystal structure and physical properties of the obtained one-dimensional ZnO arrays reveiled, which allow the formation of the nanostructured layers with predetermined properties. For the first time, we have offered a processing of the ZnO nanostructures by the ultraviolet radiation for the reversible transition of the ZnO surface from high hydrophobicity to hydrophilicity. New Ni/ZnO nanocomposite selective coatings have been obtained for the use in solar heat collectors. The base layer of a new SC with extra-thin absorber on the base of ZnO nanostructures with Se nanoparticles obtained. Experimental sample of highly selective ultraviolet detector with Al/ZnO/FTO/Al composition created. New n-ZnS/p-Cu2ZnSnS4 composition for thin film kesterite solar cell was developed on the base of Cu2ZnSnS4 layer obtained by two economic liquid-phase methods, namely by the electrodeposition and by the SILAR method. Perspective heterostructures Al/ZnS/Cu2ZnSnS4/Mo/Al and Al/Zn(O,S)/SnS/Mo/Al for SCs of a new generation have been created.
