The photoelectric conversion of solar energy depends on the cells in the solar cell components. The cells have a good light absorption effect. The cells can use the photoelectric effect to directly convert light energy into electrical energy. With the continuous improvement of solar cell components, solar energy The photoelectric conversion efficiency of the battery sheet in the battery module has reached a relatively high level, so people continue to develop and improve the light transmittance of the glass plate used as the cover material in the solar battery module, in order to further improve the entire solar power to photoelectric conversion efficiency. Purpose, because the solar cells will generate heat while generating electricity under the irradiation of sunlight, resulting in an increase in temperature, the impact of the increase in the temperature of the solar panel will affect the photoelectric conversion efficiency and reduce the power generation efficiency

[0003] At present, the Chinese invention CN211695476U discloses a heat-insulating solar glass plate, through the first glass plate and the second glass plate, cooperate with the first left side plate, the second left side plate, the first right side plate and the second right side board, to achieve the effect that the device can form a cavity, and then through the vent pipe and the water tank, the middle section of the vent pipe position is located inside the water tank, which achieves the effect of reducing the temperature of the cavity, thus making the device have a heat insulation Although it can realize the function of slowing down the temperature rise of the cells of the solar device, the structure of the device is relatively complicated, and it is not light enough. It requires a large installation space to be installed on the roof, and it needs to be used by a water pump, which will cause power consumption. , affecting the power generation of photovoltaic power generation
