Detailed Description

Embodiments of the present invention are described in detail below, and the embodiments described with reference to the drawings are exemplary.

A glazing 100 for a photovoltaic module (not shown) according to an embodiment of the invention is described below with reference to fig. 1-3.

As shown in fig. 1 to 3, a glass member 100 for a photovoltaic module according to an embodiment of the present invention may include a body 1.

Specifically, the two side surfaces in the thickness direction of the body 1 are a first surface 10 and a second surface 11, respectively, at least one of the first surface 10 and the second surface 11 is provided with a pattern portion 12, the pattern portion 12 is located at the edge of the at least one of the first surface 10 and the second surface 11, and the pattern portion 12 extends in the circumferential direction of the body 1.

Here, the phrase "the pattern portion 12 is located at the edge of the at least one of the first surface 10 and the second surface 11" may mean that the pattern portion 12 is located only at the edge of the first surface 10, or the pattern portion 12 is located only at the edge of the second surface 11, or the pattern portion 12 is located at both the edge of the first surface 10 and the edge of the second surface 11. Fig. 2 to 3 show the case where the pattern portion 12 is located at the edge of the first surface 10.

Accordingly, by providing the embossed portion 12 at the edge of the at least one surface of the glass member 100 for a photovoltaic module, the roughness of the at least one surface of the glass member 100 is increased, and the adhesive force of the glass member 100 to the silicone gel may be enhanced, so that the silicone gel is not easily detached from the edge of the glass member 100.

Specifically, when the glass member 100 is applied to a photovoltaic module, the surface of the first surface 10 and the second surface 11 of the glass member 100 having the pattern portion 12 at the edge thereof may be disposed on the side away from the photovoltaic cell group, for example, when a laminated photovoltaic module is framed such as an aluminum alloy frame, silicone gel may be coated in a groove of the frame such as the aluminum alloy frame and the edge of the glass member 100 provided with the pattern portion 12 may be bonded to the silicone gel, so that the glass member 100 may be bonded to the aluminum alloy frame by the silicone gel. Because the roughness of the edge of the glass piece 100 provided with the pattern part 12 is large, the bonding strength between the edge of the glass piece 100 and silica gel is large, so that the glass piece 100 is firmly bonded with the frame, the structural stability of the photovoltaic module is improved, and the service life of the photovoltaic module is prolonged.

According to the utility model discloses a glass piece 100 for photovoltaic module, through set up pattern portion 12 in the edge of at least one in its body 1's thickness direction's first surface 10 and second surface 11, and pattern portion 12 extends along the circumference of body 1, and the roughness of the edge of above-mentioned at least one surface of glass piece 100 is great. When the glass piece 100 is applied to the photovoltaic module, the bonding force between the edge of the at least one surface of the glass piece 100 and the silica gel is strong, so that the structural stability of the photovoltaic module can be improved, and the service life of the photovoltaic module can be prolonged.

Further, in the case where the edge of one of the first surface 10 and the second surface 11 is provided with the pattern 12, optionally, the other of the first surface 10 and the second surface 11 is textured. When the glass piece 100 is applied to a photovoltaic module, the reflection of light by the glass piece 100 can be reduced and the absorption of light by the glass piece 100 can be enhanced while the strong adhesion between the one surface of the glass piece 100 and silica gel is ensured, so that the light absorption rate of the whole photovoltaic module is improved.

Optionally, the edge of the first surface 10 and the edge of the second surface 11 are both provided with a pattern 12. When the glass member 100 is applied to a photovoltaic module, for example, the first surface 10 is farther from the photovoltaic cell than the second surface 11, since the edges of the first surface 10 and the second surface 11 are provided with the patterned portions 12, the roughness is increased, for example, the edge of the first surface 10 is firmly bonded to the aluminum alloy frame by the silicone, and for example, the edge of the second surface 11 is more strongly bonded to the ethylene-vinyl acetate copolymer (ethylene-vinyl acetate copolymer) layer in the photovoltaic module.

According to some embodiments of the present invention, the pattern part 12 is provided on the entire edge of the above at least one of the first surface 10 and the second surface 11. Thereby, the roughness of the entire edge of the above-mentioned one surface of the glass member 100 can be made large, thereby further increasing the adhesive strength of the edge of the glass member 100 with the silicone gel.

According to other embodiments of the present invention, the pattern portion 12 includes a plurality of sub-pattern portions 12 (not shown), and the plurality of sub-pattern portions 12 are provided along the circumferential direction of the body 1 at intervals. In the description of the present invention, "a plurality" means two or more. By the arrangement, the adhesive force between the edge of the glass piece 100 and the silica gel is strong, the usage amount of the silica gel is saved, and the cost is saved. Alternatively, the plurality of sub-patterns 12 may be arranged at regular intervals or non-regular intervals in the circumferential direction of the body 1.

According to some embodiments of the present invention, referring to fig. 3, the outer periphery of the pattern 12 extends to be flush with the side surface 13 of the body 1. Therefore, the bonding area between the edge of the at least one surface of the glass piece 100 and the silica gel can be increased, so that the bonding strength is further increased, and the reliable bonding between the glass piece and the silica gel can be effectively ensured. Of course, the present invention is not limited thereto, and as shown in fig. 2, the outer periphery of the pattern portion 12 may not extend to the side surface 13 of the body 1, and the outer periphery of the pattern portion is spaced apart from the side surface of the body in the radial direction.

Alternatively, referring to fig. 1, the width of the pattern portion 12 is w, where w satisfies: w is more than 0 and less than or equal to 20 mm. So set up, when glass piece 100 is applied to photovoltaic module, both can make the edge of glass piece 100 and for example frame pass through silica gel and adhere powerfully, can guarantee that the light absorbing capacity of photovoltaic cell group is not influenced again.

According to some embodiments of the present invention, referring to fig. 2, the pattern portion 12 includes a plurality of protrusions 121, one end of each protrusion 121 is connected to the at least one of the first surface 10 and the second surface 11, the other end of each protrusion 121 extends toward a direction away from the at least one of the first surface 10 and the second surface 11, and a cross-sectional area of the other end of each protrusion 121 is smaller than a cross-sectional area of the one end of the corresponding protrusion 121. With such an arrangement, while the strong adhesive force between the edge of the at least one surface of the glass member 100 and the silicone rubber is ensured, the connection area between the protrusion 121 and the body 1 is large, so that the structure of the protrusion 121 can be more stable.

Alternatively, as shown in fig. 2, the plurality of protrusions 121 are spaced apart from each other so that a larger amount of silicone gel may contact the at least one surface of the glass member 100, for example, the first surface 10, thereby increasing the adhesive strength of the silicone gel to the at least one surface of the glass member 100, for example, the first surface 10. Or alternatively, as shown in fig. 3, the one ends of the adjacent protrusions 121 are connected to each other, so that a greater number of protrusions 121 can be provided on the edge of the at least one surface of the glass member 100, such as the first surface 10, to further increase the roughness of the edge, thereby increasing the adhesive strength of the edge with the silicone.

Alternatively, each protrusion 121 may be hemispherical (as shown in fig. 2), polygonal pyramid (as shown in fig. 3), truncated cone (not shown), or the like. The projections 121 are regular in shape, easy to manufacture and convenient for mass production. But is not limited thereto.

Further, the plurality of protrusions 121 on the edge of the at least one surface of the glass member 100 may have the same shape for easy manufacturing. Of course, the shape of the plurality of protrusions 121 on the edge of the at least one surface of the glass piece 100 may also be different to further increase the roughness of the edge of the glass piece 100.

Alternatively, the pattern part 12 is pressed by a press roller. The manufacturing process of the pattern part 12 is simple and efficient. For example, the pattern portion 12 may be pressed by a press roll whose edge is provided with a pattern complementary to the pattern portion 12. Wherein the press roll may be a glass press roll.

According to the utility model discloses photovoltaic module of second aspect embodiment can include photovoltaic battery group and glass piece 100. Wherein, the glass member 100 is the glass member 100 for photovoltaic module according to the embodiment of the first aspect of the present invention.
