The implementation, functional features and advantages of the objects of the present invention will be further explained with reference to the accompanying drawings.
Detailed Description
The invention provides a solar photovoltaic module with heat insulation and cooling functions.
In an embodiment of the present invention, as shown in FIG. 1; the solar photovoltaic module with the heat insulation and temperature reduction functions comprises a back film 1, a battery piece 2, tempered glass 3 and a transparent heat insulation and temperature reduction coating 4; the thickness of the transparent heat-insulation and temperature-reduction coating 4 is 10-30 mu m, and the components and parts by weight of the transparent heat-insulation and temperature-reduction coating 4 are as follows:
55% of thermoplastic acrylic resin, 8% of micron powder, 8% of nano barium sulfate, 8% of ceramic powder, 7% of vacuum glass beads, 2% of siloxane coupling agent, 0.5% of polytetrafluoroethylene wax, 0.3% of organic silicon defoamer, 8% of mixture of xylene and butyl acetate, 3% of coating additive, and 50% of each station of xylene and butyl acetate in the mixture of xylene and butyl acetate. Wherein the micrometer powder is titanium dioxide (TiO)2) The particle size of the micron powder is 10-30 microns, and the coating additive is a dispersing agent.
And (3) coating the transparent heat-insulating and temperature-reducing coating 4 on the upper surface of the toughened glass 3 by a spraying method, and curing at the temperature of 100-200 ℃ for 0.5-1 h.
The solar photovoltaic module with the heat insulation and temperature reduction functions has the advantages that the photoelectric conversion efficiency is remarkably improved, the solar photovoltaic module is subjected to sunshine with the energy density of 800W/m2 under the condition that the air temperature is 300K (about 27 ℃), and the surface temperature of an unmeasured solar cell is increased to 342.3K (about 69 ℃). The power generation performance of the outdoor type solar cell is mostly rated at a temperature of 25 ℃. Moreover, the crystalline silicon solar cell has poor tolerance to temperature rise, and the output power decreases by 0.45% for every 1K rise in temperature. At a surface temperature of 69 c, the temperature rises by about 42K from the nominal condition, resulting in a drop in output power of about 19%. In the case of a solar cell with a 20% conversion efficiency rating, the conversion efficiency actually exhibited under this condition is only about 16%. The invention can control the temperature rise amplitude under 800W/m2 sunshine at 17.6K. In this case, the surface temperature of the solar cell is only about 52 ℃, and the output power is reduced by only about 11%. The solar cell having the above conversion efficiency of 20% actually operates at a conversion efficiency of about 18%.
Meanwhile, the existing photovoltaic module is cooled by using other materials or combination forms on the back surface, and the structure is complex. The invention adopts a mode of cooling from the front side of the photovoltaic module and has strong infrared heat insulation and cooling functions. Therefore, the combination form of the present invention is original.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
