Solar photoelectric and photothermal conversion device

The invention discloses a solar photoelectric and photothermal conversion device, comprising a chassis and top glass. The device is characterized in that a hollow ceramic plate is arranged in a sealed cavity which is vacuumized and positioned between the chassis and the top glass; the hollow ceramic plate is formed by a thermodynamic medium outlet pipe and a thermodynamic medium inlet pipe which are separated from each other; a ceramic joint is provided with a thermodynamic medium outlet and a thermodynamic medium inlet; supports are arranged between the top glass and the chassis in the sealed cavity. A solar energy conversion layer is fixed at the top of the hollow ceramic plate. The solar cell converts the collected solar energy into electricity, and the radiation energy transmitting the solar cell is absorbed by the thermodynamic medium in the hollow ceramic plate and the thermodynamic medium serves as a thermo-carrier to output useful energy. The device has the advantages of comprehensively utilizing the
