COMBINED PRODUCTION OF HEAT AND ELECTRIC ENERGY FOR RESIDENTIAL AND INDUSTRIAL BUILDINGS WITH APPLICATION OF SOLAR ENERGY Russian patent published in 2014 - IPC H01L31/42 H01L35/30 B82B1/00 

FIELD: electricity.

SUBSTANCE: in accordance with the invention claimed solar-powered generator (100) contains thermoelectric elements adjoining solar elements and located below solar elements. Concentrated flow of solar energy is provided. Heat sink (104), with changeable temperature and efficiency, contacts with cold soldered seam (108) of thermoelectric device (103). Thermal resistance is calculated with respect to energy flow, which results in creation in thermoelectrical device (103) of temperature gradient equal to several hundreds of Kelvin degrees. Solar element preferably contains semiconductor with large width of prohibited energy zone. Generator (100) preserves relatively suitable efficiency (efficiency factor) in some range of cold seam (108) temperature. System of hot water can serve as heat sink (104). High values of efficiency factor are obtained due to application of nanocomposite thermoelectrical materials. One-piece construction of solar element and thermoelectrical elements provides additional advantages.

EFFECT: uniformly but sparsely distributed thermoelectrical segments in matrix from material with high heat-insulating properties reduces quantity of material required for segments without impairment of working characteristics.
