Problems solved by technology

However, due to this combination method, due to the poor heat conductor in the solar cell module, the combined heat transfer area between the heating body and the solar cell back plate is small, the heat transfer efficiency is low, and the cost is high.
The current liquid immersion cooling method, due to the problem of liquid flow control, the heat transfer effect of the battery is not very good, and the uneven temperature distribution has an impact on the battery efficiency

Abstract

This invention discloses a common use device for electricity and heat of a solar cell including a liquid container with heat collection working fluid, in which, hot tubes are set on the side walls of the container and set with phase change heat- carry working fluid, a solar cell is connected with the tubes in the container fixedly, an inlet is set at the bottom of the container and an outlet is set at the top of the container, the bottom face is transmissive, heat preservation materials are set at outside of the top and outside of the side wall of the container. This invention can carry away solar heat not changed to electricity quickly by dipping a solar cell in a heat-collection working fluid and connecting to the hot tubes.

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...
