Description

technical field [0001] The invention relates to a thermoelectric direct conversion device, in particular to a general thermal photovoltaic power generation system using electric heating as an alternative energy source. Background technique [0002] The thermal photovoltaic system heats the radiator through a heat source (isotope energy, solar energy, combustion, etc.), and effectively modulates the radiation band through the thermal radiator to obtain high conversion efficiency. The principle is: heat the radiator through the heat source to make it reach a higher temperature, so as to emit radiant energy to the outside. A spectral filter is set between the radiator and the photocell, so that the radiant energy within the convertible wavelength range of the battery reaches the battery through the filter, and is converted into electrical energy by the photocell for external output, while the energy that the battery cannot convert is reflected back by the filter The radiator c...

Problems solved by technology

[0006] It can be seen that compared with the existing thermoelectric conversion forms such as thermoelectric power generation systems, the efficiency of thermo-photovoltaic systems has been improved to a certain extent. There are two forms of solar heating, and the system structure is relatively diverse, but it lacks versatility. In order to achieve future interface matching with isotope heat sources, it is necessary to design a general-purpose thermoelectric conversion device that has certain versatility and can be used by directly replacing the heat source.
