Description

technical field

[0001] The invention relates to a cascaded utilization device of solar energy, in particular to an electric-heat combination device of a solar cell. Background technique

[0002] In the future, the large-scale utilization of solar energy will be used to generate electricity and realize the transformation from supplementary energy to alternative energy. The basic principle of photoelectric conversion is to use the photovoltaic effect to directly convert solar radiation energy into electrical energy, and its basic device is a solar cell. At present, the main obstacle to the large-scale popularization and application of solar cell power generation is the high cost.

[0003] Solar cells become less efficient as their temperature increases. So how to effectively take away the solar radiant heat that is not converted into electricity by the solar cell is a problem. At present, the cooling methods of photovoltaic cells are divided into active and passive. The he...
