Embodiment 1

[0056] Mesh-shaped golden LED coating formula (mass percentage of raw materials):

[0057]

[0058] Stir the components in the above formula evenly, and print the above golden paint on the glass surface with a 200-mesh dot-shaped screen plate to obtain a color coating with a thickness of 21 microns, a light-transmitting aperture of 1 mm, and a light-transmitting area of ​​10%. The light-curing wavelength is 395nm, and the irradiation energy is 700mJ / cm2; the light-cured glass is heated at 160°C for 10 minutes to obtain a mesh-shaped golden solar glass panel.

[0059] When viewed from a distance, it looks like golden glass with uniform color, and when viewed closely, the surface is distributed with light-transmitting sieve holes. The physical and chemical indicators such as light transmittance are measured, see attached table 1.

Embodiment 2

[0061] Mesh-shaped silver-white LED coating formula (mass percentage of raw materials):

[0062]

[0063] Stir the components in the above formula evenly, and print the above golden paint on the glass surface with a 200-mesh dot-shaped screen plate to obtain a color coating with a thickness of 17 microns, a light-transmitting aperture of 1 mm, and a light-transmitting area of ​​17%. The light-curing wavelength is 395nm, and the irradiation energy is 500mJ / cm2; the light-cured glass is heated at 170°C for 8 minutes to obtain a mesh-shaped silver-white solar glass panel.

[0064] The color is uniform and silvery-white glass when viewed from a distance, and the surface is distributed with light-transmitting sieve holes when viewed from a close distance. The physical and chemical indicators such as light transmittance are measured, see Attached Table 1.

Embodiment 3

[0066] Mesh-shaped red LED coating formula (mass percentage of raw materials):

[0067]

[0068] Stir the components in the above formula evenly, and print the above colored paint on the surface of the photovoltaic glass with a 200-mesh dot-shaped screen plate to obtain a red mesh coating with a thickness of 22 microns, a light-transmitting aperture of 1 mm, and a light-transmitting area of ​​25%; The wavelength of LED light curing is 395nm, and the irradiation energy is 1000 mJ / cm2; the light-cured glass is heated at 180°C for 5 minutes to obtain a mesh-shaped red solar glass panel.

[0069] From a long distance, it looks like red glass with a uniform color, and from a close view, there are light-transmitting sieve holes on the surface, and the physical and chemical indicators such as light transmittance are measured, see attached table 1.

Abstract

The invention discloses a solar panel with a sieve-hole-shaped colored coating and a production method of the solar panel. The production method comprises the following steps: (1) designing and manufacturing a screen printing plate with a dotted array photosensitive pattern; (2) through-printing the LED curing colored paint on a transparent substrate through a screen printing plate to form a sieve-hole-shaped colored coating with light-transmitting through holes; (3) irradiating the coating with LED ultraviolet light to preliminarily cure the coating; (4) heating and curing the primarily cured coating to form a solar panel with a sieve-hole-shaped colored coating. The LED curing color paint comprises the following raw materials in percentage by mass: 45-65% of an LED photosensitive polymer; 12-27% of a photoactive diluent; 1-5% of a photosensitizer; 1-2% of an adhesion promoter; 3-15% of a pigment; 0.5-2% of an ultraviolet light absorber; and 0.01-3% of a leveling agent. The invention also discloses an application of the solar panel in a colored solar photovoltaic module. The contradiction that the attractiveness and the light transmittance of a solar product cannot be unified is creatively solved.

Description

technical field [0001] The invention relates to the field of solar photovoltaics, in particular to a solar panel with a sieve-shaped colored coating, a production method thereof, and a colored solar photovoltaic module. Background technique [0002] If photovoltaics want to enter the city, aesthetics must come first. For solar energy to enter the city, it must meet the aesthetic needs of the public. Aesthetics is the premise. No matter how high the power generation efficiency of solar energy is, if it does not change its original appearance of black, ugly, and stupid, it will not be able to be promoted in large quantities in cities. Colored solar energy is the key to urban carbon. and the rigid demand. [0003] Since the solar cells are dark blue or black, the solar modules are also dark. How to make blue-black photovoltaic modules present bright colors without reducing light transmittance or affecting photoelectric conversion efficiency has become a technical obstacle for...
