Аннотация
The paper presents the results of a study of the possibility of highly efficient conversion of solar energy and heat using photothermoelectric converters (FTC). Design solutions of the device are shown. In this article, we conducted a literature analysis of the development of technology for the development and research of highly efficient combined solar and thermoelectric generators that simplify the operation of renewable energy sources, as well as increase the efficiency of photothermal devices. The theory of thermoelectric compatibility was explored to provide analytical solutions for device efficiency in idealized materials with temperature dependent properties. The methods of theoretical calculation of the mechanism of absorption and refraction of light were analyzed. The article presents the radiation of a selected wavelength in the volume of a photoelectric converter and the design of an efficient photothermal converter with a fixed slit. The possibility of optimal distribution of the light spectrum on the frontal surfaces of the solar cell and thermoelectric converter has been studied. According to the results of experimental studies, it was concluded that the efficiency of the photoconverter increases by 3 times compared to analogues, but operating without a thermal converter. A comparative analysis of the results of both foreign and domestic scientific developments is given.
