Embodiment 1

[0058] Honeycomb golden UV coating formula (raw material mass percentage):

[0059]

[0060] Stir the components in the above formula evenly, and use a 200-mesh screen plate to print the above-mentioned color coating on the surface of the photovoltaic glass to obtain a color coating with a thickness of 25 microns; preheat at 50 ° C for 30 seconds, so that the coating is fully defoamed and leveled; UV light curing, the irradiation energy is 800 mJ / cm2; a green laser with a wavelength of 532 nm and a power of 10 watts is used to make holes at an angle of 45 degrees to the glass, the aperture is 15 microns, and the ratio of the hole to the coating area is 10%; The glass after the hole is left to dry naturally at room temperature for 18 hours, and a honeycomb golden solar glass panel is obtained. Long-distance viewing is golden glass with uniform color, and physical and chemical indicators such as light transmittance are measured, see Appendix 1.

Embodiment 2

[0062] Honeycomb silver UV coating formula (raw material mass percentage):

[0063]

[0064] Stir the components in the above formula evenly, apply a color coating with a thickness of 18 microns on the surface of the photovoltaic glass by roller coating; preheat at 50 °C for 30 seconds to fully defoaming and level the coating; UV light curing, irradiation energy of 600 Millijoule / square centimeter; the light-cured glass is perforated with a green laser with a wavelength of 532 nm and a power of 10 watts at an angle of 45 degrees to the glass, the aperture is 15 microns, and the ratio of the hole to the coating area is 20%; after perforation The glass was placed at room temperature for 24 hours to further dry and solidify the coating, that is, a honeycomb silver solar glass panel was obtained.

Embodiment 3

[0066] Honeycomb white UV coating formula (raw material mass percentage):

[0067]

[0068] Stir the components in the above formula evenly, and use a 200-mesh screen plate to print the above-mentioned color coating on the surface of the photovoltaic glass to obtain a color coating with a thickness of 22 microns; preheat at 50 ° C for 30 seconds, so that the coating is fully defoamed and leveled; UV light curing, irradiation energy 1000 mJ / cm2. Use a green laser with a wavelength of 532 nanometers and a power of 10 watts to drill holes at a 45-degree angle to the glass, with a pore size of 15 microns and a hole-to-coating area ratio of 25%. A white honeycomb glass coating was prepared, which was viewed from a long distance as white glass with uniform color. When viewed from a close distance, there were many oblique light-transmitting small holes distributed on the surface of the coating.

Abstract

The invention discloses a solar panel with a honeycomb-shaped color coating, a production method thereof, and a color solar photovoltaic assembly. The production method comprises the following steps: coating a UV color coating on a transparent substrate, and preheating the transparent substrate; After preheating, ultraviolet light is used to irradiate the UV color coating, and the UV color coating is initially cured; the laser beam is used to obliquely punch or scribe the UV color coating after preliminary curing to form light-transmitting holes or grooves, so that the The UV color coating forms a honeycomb structure; the UV color coating after perforation is post-cured to form a solar panel with a honeycomb color coating; in terms of the mass percentage of raw materials, the UV color coating includes: photopolymerization 50-70% of organic matter; 10-25% of low-viscosity photoactive diluent; 1-5% of photosensitizer; 1-15% of pigment; 0.5-2% of UV absorber; 0.01-3% of leveling agent. The UV color coating of the present invention has a honeycomb structure, so that the light transmittance of the solar panel is significantly improved.

Description

technical field [0001] The invention relates to the field of solar photovoltaic, in particular to a solar panel with a honeycomb-shaped color coating, a production method thereof, and a color solar photovoltaic assembly. Background technique [0002] my country's building carbon emissions account for more than 1 / 3 of the total carbon emissions, and the new building area is about 2 billion square meters every year. Building-integrated photovoltaics (BIPV) are emerging as the solution for creating green buildings. [0003] BIPV is a technology that integrates solar power generation products into buildings. Literally, it means to allow buildings to generate electricity by themselves, and to directly combine photovoltaic cells and building materials into components, such as wall tiles, tiles, and curtain walls. As one of the best routes for the development of photovoltaic scenario-based applications in the future, BIPV has important demonstration and promotion significance for ...
