The purpose of the work is to establish the patterns of influence of technological production factors, chemical composition and formation of solid solutions on the physicochemical properties of materials based on lead and cadmium chalcogenides, transition metal oxides for the creation energy of thermoelectric, photoelectric and electrochemical sources. The research method is to analyze the influence of technological factors of production, chemical composition and morphology of synthesized materials on thermoelectric, photoelectric and electrochemical properties for the creation of renewable energy sources. The theoretical and experimental studies of the structural, electrophysical and physicochemical properties of materials carried out by scientists of the department made it possible to establish optimal technological conditions for their production for the creation of alternative energy sources on their basis (thermal generators, photovoltaic batteries and batteries). In particular, lead telluride (8%) doped with a pipe leads to a sharp increase in the thermoelectric figure of merit (from 0.6 to 1.6) due to a decrease in the thermal conductivity coefficient. The prospects for using CdTe-based surface diodes in solar energy have been proven and methods for modifying their physical properties have been proposed. The chemical composition has been established and the technological factors for obtaining solid solutions based on PbTe and PbSnAgTe compounds with a high thermoelectric figure of merit (ZT=1.25 at 470 K), which are suitable for the manufacture of electric thermogenerators, have been determined. The promise of synthesized composite nanostructures based on transition metal compounds and cellular carbon for the creation of efficient electr Product Description popup.authors VAKALIUK Vasyl M.
