Description

Technical Field

[0001] The invention relates to a solar double-sided photovoltaic cell assembly, in particular to a liquid light funnel reflective focusing high-efficiency liquid-cooled double-sided photovoltaic cell assembly, belonging to the field of renewable energy. Background Art

[0002] The energy reaching the ground from the sun is as high as 800,000 kilowatts per second. 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 broad 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, relying on natural air cooling. Due to the slow air flow, the cooling effect is not good. In addition, the conventional solar double-sided photovoltaic cell modules have poor heat storage capacity. Under sunlight, the temperature of the photovoltaic cells rises sharply. When the sun sets, the temperature of the photovoltaic cell modules drops rapidly, which is completely against the natural ecology. The temperature of the 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 the photovoltaic cell modules are installed, and the rising air flow 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

A light funnel module corresponding to the hollow interlayer is placed, and a transparent antifreeze solution with a refractive index similar to that of the tempered glass is filled. Therefore, under the condition of little influence on the sunlight transmittance, because the specific heat of the transparent antifreeze solution is much higher than that of air and glass, it has a good cooling and heat storage effect on the solar double-sided photovoltaic cell assembly, so that the transparent antifreeze solution cools down at night and heats up during the day, and maximizes the good restriction and buffering effect on the temperature rise of the solar double-sided photovoltaic cell assembly. And because its structure is a sandwich between ultra-white tempered glass and the base, it is filled with a transparent antifreeze solution under negative pressure or vacuum, and the transparent antifreeze solution is an incompressible liquid medium, so that the light and photovoltaic cell utilization rate of the liquid light funnel reflection and concentration high-efficiency liquid-cooled double-sided photovoltaic cell power generation assembly is high. At the same time, the device is tightly pressed under the action of atmospheric pressure, and the force is evenly applied, which greatly improves its strength and safety, and solves the problem that the solar bifacial photovoltaic cell module has a high surface temperature, which reduces the power generation efficiency of the solar bifacial photovoltaic cell module. Due to the scattering effect of sunlight in glass and transparent antifreeze solution, the hot spot effect of the solar bifacial photovoltaic cell module caused by the obstruction of debris is reduced. The solar bifacial photovoltaic cell module heats up and cools down quickly, which leads to a large temperature difference between day and night in the installation area, and the inversion layer cannot be continuously generated at night due to the inability to generate rising airflow.

The gap between the interlayer between the glass vacuum tube row and the concave bottom plate is interconnected, and the closed-loop concave bottom glass plate is sealed and connected as a whole along the support head frame through a bonding agent and a tempered glass plate of corresponding size, forming a photovoltaic cell assembly and a concave bottom plate clamping a glass vacuum tube row plate.

[0072] The antifreeze solution is filled into the gaps between the photovoltaic cell assembly, the concave bottom plate and the glass vacuum tube row through the injection nozzle, and then the injection nozzle is closed after evacuation. Alternatively, the high-temperature transparent antifreeze solution is filled into the gaps between the photovoltaic cell assembly, the concave bottom plate and the glass vacuum tube row, and then the injection nozzle is closed to allow the transparent antifreeze solution to cool and shrink to form negative pressure, thereby forming a high-efficiency liquid-cooled double-sided photovoltaic cell power generation assembly that clamps the glass vacuum tube row and is placed in a liquid light funnel for reflection and focusing.

[0074] After the antifreeze solution fills the gaps between the photovoltaic cell assembly, the concave bottom plate and the glass vacuum tube row, it has a good thermal insulation effect. At the same time, because the specific heat of the transparent antifreeze solution is much higher than that of gas and glass, it plays a good buffering role in the temperature rise and fall heat exchange on both sides of the liquid light funnel reflective focusing high-efficiency liquid-cooled double-sided photovoltaic cell power generation assembly. And because the transparent antifreeze solution is filled under negative pressure or vacuum after the photovoltaic cell assembly, the gaps between the concave bottom plate and the glass vacuum tube row are filled, and the transparent antifreeze solution is an incompressible liquid medium, the liquid light funnel reflective focusing high-efficiency liquid-cooled double-sided photovoltaic cell power generation assembly is tightly combined under the action of atmospheric pressure, so that the force is uniform, and the strength and safety are greatly improved.
