Embodiment 1

[0037] Such as figure 1As shown, a double-glass photovoltaic module, the photovoltaic module includes a front glass 1, a front sealing adhesive film 2, a battery string 3, a rear sealing adhesive film 4 and a back glass 5 arranged in sequence; the front glass 1 and The back glass 5 adopts double-sided coated glass; the double-sided coated glass includes glass 6 and grid-shaped glaze layer 7 and anti-reflection film layer 8 respectively arranged on two opposite surfaces of glass 6; wherein : the glaze layer 7 on the front glass 1 mainly plays the role of shielding and improving the aesthetics, and the glaze layer 7 arranged on the back glass 5 is coated with a highly reflective material to increase the utilization of interstitial light;

[0038] The preparation process of the above-mentioned double-sided coated glass comprises the following steps:

[0039] S1. Glass pretreatment: cut the glass 6 as required, then polish the surroundings of the glass to make it smooth, and wash...

Embodiment 2

[0046] The difference between embodiment 2 and embodiment 1 is that what the front glass 1 in embodiment 2 adopts is the single-sided coated glass that is only coated with the anti-reflection film layer 8, and the glaze layer 7 is not provided; the remaining conditions of embodiment 2 are all the same. Same as Example 1.

Abstract

The invention discloses a double-glass photovoltaic module and a preparation method thereof. The photovoltaic module sequentially comprises front glass, a front packaging adhesive film, a battery string, a rear packaging adhesive film and back glass; the front glass and the back glass adopt double-sided coated glass; the preparation process of the double-sided coated glass comprises the following steps: S1, cutting glass into a required size, carrying out polishing, and carrying out cleaning to remove surface impurities; S2, printing glaze on the surface of the glass to form a glaze layer; S3, curing and cooling the glass; S4, turning over the glass, and then coating the glass with antireflection film coating liquid to form an antireflection film layer; and S5, tempering the glass, detecting a finished product, and packaging the glass. The preparation process of the double-glass photovoltaic module comprises the following steps that a lead hole is formed in the back glass, a front packaging adhesive film, a battery string, a rear packaging adhesive film and the back glass are sequentially laid on the front glass, the front packaging adhesive film and the rear packaging adhesive film are attached to the glaze layers on the front glass and the back glass respectively, positive and negative leads in the battery string are led out from the lead hole, and the double-glass photovoltaic module is manufactured through lamination.

Description

technical field [0001] The invention relates to the technical field of solar power generation, in particular to a double-glass photovoltaic module and a preparation method thereof. Background technique [0002] The basic structure of crystalline silicon solar double-glass modules includes front glass, upper packaging material, cell layer, lower packaging material and back glass in sequence. [0003] At present, the technical route of double-glass components is developed from single-sided double-glass transparent components to double-sided double-glass transparent components, double-sided double-glass grid AR components, double-sided double-glass grid AR components, and to double For double-sided glass grid anti-reflection and anti-reflection components, the back glass needs to be coated on both sides, one side is coated with grid glaze to increase the utilization of gap light, and the other side needs to be coated with an anti-reflection film layer to increase the back light...
