DETAILED DESCRIPTION - The photovoltaic and thermoelectric power generating device comprises a structure and a thermoelectric converter. The structure includes a photovoltaic cell (100) and a thermally conductive backsheet. The thermally conductive backsheet is disposed below the cell. The thermoelectric converter: is thermally coupled to the structure at a high-temperature end of the thermoelectric converter to receive a portion of generated heat such that a temperature differential is achieved across the thermoelectric converter; is electrically coupled to feed current to the photovoltaic cell; is electrically coupled to feed current separate sources; is located at harmonically optimum locations to increase a vibration; and comprises a hard ferromagnet, a soft ferromagnetic material and pairs of P-type and N-type thermoelectric elements. The photovoltaic cell: has a thermally conductive substrate comprises a material to absorb a spectrum not absorbed by an absorber layer in the photovoltaic cell; and is formed on a solar selective metal absorber with a thermal conductivity of 40 k-W/(m.K). The solar-electrical generator exhibits a solar energy conversion of 4%. A temperature difference between the high-temperature and a low-temperature ends of the thermoelectric converter is 50 degrees C. The thermally conductive substrate comprises a metal foil, a metallized plastic, or polymer. The thermoelectric converter and the photovoltaic cell are thermally and physically integrated by physically separated by the back sheet, and are electrically integrated. An elastic material is sandwiched the hard ferromagnet and the soft ferromagnetic material to improve a rebound effect and facilitate an oscillation. Each pairs of P-type and N-type thermoelectric elements are electrically coupled in series and thermally coupled in parallel between first and second thermally conductive plates. Heat is received from the solar absorber by a hot side of the thermoelectric converter. Electricity is generated the thermoelectric converters. The heat is provided heat from a cold side of a set of thermoelectric converters to a fluid that is provided into a solar fluid heating system or a solar thermal to electrical conversion plant.
