Embodiment 1

[0039] Such as Figure 1-2 , a panel for solar photovoltaic cells, comprising a substrate 1, on which a pattern area 2 is distributed, and a plurality of pattern area optical structural unit configurations 3 are arranged and fixed on the pattern area 2. The optical structural unit configuration 3 in the pattern area forms a brick-shaped pattern, and there are blank areas 4 between the pattern areas, that is, contrast areas. The optical structural unit configuration 3 in the pattern area is a square (also can be linear, curved, or one or more of circular, elliptical, rhombus, triangle, rectangular, trapezoidal, parallelogram, linear, curved) Regular or irregular shapes composed of shapes, preferably rhombus, triangle.).

Embodiment 2

[0041] Such as Figure 3-4 , a panel for solar photovoltaic cells, comprising a substrate 1, a pattern area 2 is distributed on the substrate 1, and a plurality of pattern area optical structural unit configurations 3-1 are arranged and fixed on the pattern area 2. The optical structural unit configuration 3-1 in the pattern area forms a tile-shaped pattern (also can be a marble pattern or a bluestone pattern).

[0042] The optical structure unit configuration 3-1 in the pattern area is a square (also can be linear, curved, or one of circular, elliptical, rhombus, triangular, rectangular, trapezoidal, parallelogram, linear, and curved) Regular or irregular shapes composed of one or more shapes, preferably rhombus, triangle.).

[0043]The optical structural unit configurations 3-1 in the pattern area are closely arranged. The optical structural unit configuration 3-1 in the pattern area achieves the three-dimensional effect of the pattern through the arrangement density and t...

Embodiment 3

[0047] Embodiment 3 The preparation method of the glass panel that solar photovoltaic cell is used

[0048] Transfer UV-curable transparent transfer adhesive on the substrate according to the pattern to form the configuration of the optical structural unit in the pattern area; the transfer UV-curable transparent transfer adhesive includes the following steps:

[0049] Embossing film: use high-precision laser engraving technology to make UV-curable transparent transfer adhesive into embossed transfer film with different texture patterns;

[0050] Lamination film: Cover the transfer film with the pattern to be transferred on the outer surface of the substrate coated with UV-curable transparent transfer adhesive;

[0051] Curing: irradiated with UV lamp;

[0052] Release: the transfer film is peeled off from the substrate to obtain a glass panel with an optical structural unit configuration in the pattern area.

[0053] The substrate is preferably glass coated with a mirror-eff...

Abstract

The invention belongs to the field of assembled green energy-saving building and solar energy comprehensive utilization technologies and relates to a glass panel for the thin film power generation field of glass curtain walls or glass roofs for building facades, in particular to a glass panel for a solar photovoltaic cell and a preparation method of the glass panel. The panel for the solar photovoltaic cell comprises a substrate; a pattern area is distributed on the substrate; a plurality of pattern area optical structure unit configurations are arranged and fixed on the pattern area. With theglass panel for the solar photovoltaic cell and a preparation method of the glass panel of the invention adopted, luminous flux is not changed, and the sharp decrease of the light transmittance of incident light can be avoided, and power generation efficiency can be ensured; the change of the degree of color shading is generated by means of the structural change of the geometric configurations, and therefore, the visual impact of decorative patterns can be highlighted; and the decorativeness of photovoltaic glass curtain walls and roofs can be enhanced, and production costs will not be significantly increased.

Description

technical field [0001] The invention belongs to the technical field of prefabricated green energy-saving buildings and comprehensive utilization of solar energy, and in particular relates to a glass panel in the field of thin-film power generation for glass curtain walls or glass roofs used on building facades, in particular to a glass panel for solar photovoltaic cells and its preparation method. Background technique [0002] According to data, building energy consumption accounts for about 1 / 4 of my country's total energy consumption. Therefore, with the rapid economic development and the acceleration of urbanization, energy demand continues to increase, which intensifies the energy crisis. How to promote building energy conservation has become a hot issue that needs to be solved urgently. At present, prefabricated green and energy-saving buildings have become a bright spot in building energy conservation due to their advantages such as fast construction speed, labor-savi...
