A solar photovoltaic power generation system is arranged on the artificial floating island to provide electric energy for the operation of the above-water aeration equipment, a photovoltaic module structure is adopted at present, and due to the difference of refractive indexes between photovoltaic glass and air, the photovoltaic glass still has partial reflection on visible light. The transmittance of light can be greatly improved by coating an antireflection layer on the surface of the photovoltaic glass, so that the power of the photovoltaic cell module is improved. Antireflection glass is also increasingly used due to its higher light transmittance and higher light conversion efficiency.
At present, the antireflection glass for the components mainly adopts methods such as magnetron sputtering, chemical deposition or chemical corrosion to prepare a single-layer or multi-layer porous oxide film structure on the surface of the glass.

Comparative example
Commercially available antireflective photovoltaic glass.
In order to obtain the optimal addition amount of each raw material in the film layer formula for protecting the antireflection layer of the photovoltaic panel, a large number of experimental screenings are performed on each material (examples 1 to 13), and the infrared transmittance, light transmittance, hardness, wear resistance and heat dissipation performance of the film layer after the materials with different proportions are added are tested and counted, which is specifically shown in table 1.
The following test methods were used for each property:
1. thermal infrared transmittance: an Agilent Cary 5000 ultraviolet visible near-infrared spectrophotometer is adopted for testing, and the testing wave band is mainly concentrated at 1100-3000 nm;
2. testing of light transmittance: according to a total light transmittance (standard JIS7361) test method, an Agilent Cary 5000 ultraviolet visible near infrared spectrophotometer is adopted for testing;
3. and (3) testing pencil hardness: the pencil hardness was measured using a hand-held pencil hardness tester according to JIS K5600, with a load of 750g, using a mitsubishi special pencil.
4. And (3) testing weather resistance: the method comprises the steps of simulating sunlight irradiation by utilizing fluorescent ultraviolet rays, simulating rain by spraying distilled water, testing a tested material in an illumination cycle program (4H illumination and 4H condensation cycle) at a certain temperature (60 ℃ illumination and 50 ℃ condensation), testing the appearance of a film layer after testing for several days or weeks, namely, detecting the gloss, color change, bubbles, cracks and size stability of the film layer, and determining the film layer to be qualified if no change exists.
TABLE 1
As can be seen from table 1, the material ratio in the film layer formulation for protecting the antireflective layer of the photovoltaic panel has an important influence on the performance after film formation, and the optimal ratio can be obtained through reasonable screening.
Examples 1 to 5 show that the film layer formulation is: 50-70 parts of epoxy modified polyacrylic resin, 1-5 parts of curing agent, 2-8 parts of infrared reflection filler, 1-5 parts of heat dissipation filler, 1-10 parts of self-cleaning filler, 0.2-0.6 part of flatting agent and 15-30 parts of solvent, the light transmittance of the photovoltaic panel is not reduced by the film layer, the infrared transmittance is greatly reduced due to the addition and reasonable proportion of the infrared reflection filler, the heat dissipation filler and the self-cleaning filler, the temperature of the inner layer can be greatly reduced, the efficiency of the component in the actual use process is improved, meanwhile, the surface hardness of the coating is higher, the hardness is more than 2H, the scratch and scratch resistance is realized, and the weather resistance is good.
Examples 6 and 7 showed that the film-forming effect was not good and the weather resistance was not satisfactory as compared with example 1, and thus 50 to 70 parts of the epoxy-modified polyacrylic resin and 1 to 5 parts of the curing agent showed the best film-forming effect, and the obtained film layer showed the lowest infrared transmittance and the best light transmittance.
Compared with the example 1, the examples 8 and 9 show that when the infrared reflective filler is used in a small amount or is not used, the infrared transmittance is high, and the light transmittance is high; when the infrared reflection filler is large in material consumption, the film forming effect is poor, the light transmittance is reduced, and the infrared transmittance of the film layer is high, so that the optimal material consumption of the infrared reflection filler is 2-8 parts.
Examples 10 and 11 compare with example 1, and it is clear that when the heat dissipation filler is small or absent, the infrared transmittance is small and the light transmittance is large; when the heat dissipation filler is large in material consumption, the film forming effect is poor, the light transmittance is reduced, and the infrared transmittance of the film layer is high, so that the optimal material consumption of the heat dissipation filler is 1-5 parts.
Examples 12 and 13 show that, when the self-cleaning filler is used in a small amount or is absent, the infrared transmittance is small and the light transmittance is high, as compared with example 1; when the heat dissipation filler is large in material consumption, the film forming effect is poor, the light transmittance is reduced, and the infrared transmittance of the film layer is high, so that the optimal material consumption of the self-cleaning filler is 1-10 parts.
In the photovoltaic industry, the energy of infrared light and photons is too low to excite carriers, and the solar cell does not respond to the infrared light, so that the solar cell cannot generate electricity at night. The quantum efficiency of most solar cells is reduced by recombination effects. By "recombination effect" is meant that the excited charge carriers do not efficiently enter the external circuit (power generation). For example, the significant recombination of short wavelength light (violet or ultraviolet) at the front surface, which is absorbed in close proximity to the cell surface, will affect the solar cell quantum efficiency of the solar cell in the vicinity of that wavelength. That is, the solar cell has a low utilization rate for light having a short wavelength. Light of medium wavelength is absorbed by the main body of the solar cell, excited carriers easily enter an external circuit, and quantum efficiency is high.
Therefore, in general, solar cells respond better to light of a medium wavelength (e.g., blue, green, red). Infrared light, short wavelength light (violet light or ultraviolet light) are not only not well-suited for solar cells, but also affect the efficiency of photovoltaic modules, including photovoltaic panels. According to the invention, through the synergistic effect of the components, the light transmittance of the photovoltaic panel is maintained, infrared rays are reflected, and the self-cleaning of the photovoltaic panel is realized by using ultraviolet rays.
The above-mentioned embodiments only express the specific embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
