Description

Technical Field

[0001] The utility model relates to a solar photovoltaic cell assembly, in particular to a high-efficiency liquid-cooled solar photovoltaic cell assembly, belonging to the field of renewable energy. Background Art

[0002] The energy from the sun reaching the ground every second is as high as 800,000 kilowatts. If 0.1% of the solar energy on the earth's surface is converted into electricity, and the conversion rate is 5%, the annual power generation can reach 5.6×1012 kilowatt-hours, which is equivalent to 40 times the current energy consumption in the world. Therefore, with abundant solar energy resources, the photovoltaic power generation industry has great development prospects.

[0003] With the requirements of low-carbon development in my country, solar photovoltaic power generation has flourished and has become a trend. At present, conventional flat-plate silicon photovoltaic cell power generation devices do not track the sun, and the technology is highly mature and reliable. However, the photoelectric conversion efficiency of commercial photovoltaic cells is generally 10% to 20%. In other words, nearly 80% of solar energy is not reasonably utilized and converted into heat energy, which leads to an increase in the temperature of photovoltaic cells. For every 1 degree increase in the temperature of photovoltaic cells, the efficiency decreases by about 0.5%. That is, if the surface temperature of photovoltaic cells is too high, it will seriously affect the power generation efficiency of photovoltaic cells. Moreover, monocrystalline silicon photovoltaic cells will produce hot spot effects due to foreign matter blocking, affecting their power generation and even damaging photovoltaic cells.

[0004] At present, photovoltaic cells use natural heat dissipation, which relies on natural cooling of air. Due to the slow air flow, the cooling effect is not good. In addition, the conventional solar photovoltaic cell modules have poor heat storage capacity. Under sunlight, the temperature of photovoltaic cells rises sharply. When the sun sets, the temperature of photovoltaic cell modules drops rapidly, which is completely against the natural ecology. The temperature of photovoltaic cell modules is very high during the day and drops rapidly at night, which increases the temperature difference between day and night in the area where photovoltaic cell modules are installed, and the upward airflow cannot be continuously generated, resulting in an inversion layer phenomenon in the atmosphere.

[0005] Moreover, when the photovoltaic cell curtain wall is combined with the building, in the summer, the waste heat generated by the photovoltaic cells will increase the indoor temperature and affect the comfort of the indoor environment. In winter, the photovoltaic cell power generation module has a poor indoor insulation and heating effect, resulting in a waste of heat energy. Therefore, reducing its temperature during illumination, improving the power generation efficiency of photovoltaic cells, and solving its hot spot effect have become the key points of technical research. Therefore, there is an urgent need for a low-cost, reliable, building material that can be used as a building material, achieve integration with buildings, reduce power generation costs, and imitate the natural environment, and avoid the problem of high temperature of photovoltaic cells during the day, rapid cooling at night, and increased temperature difference between day and night. It can generate continuous updrafts to solve the problem of inversion layer, which will become the development direction of photovoltaic power generation. Summary of the invention
