This can lead to unstable glue overflow at the edges of the photovoltaic module, reducing the sealing performance and encapsulation effect. At the same time, uneven stress at the edges of the photovoltaic module can also cause microcracks or even fragmentation, increasing costs.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0035] This embodiment provides a photovoltaic module with a support structure, which solves the problem of unstable adhesive overflow at the edge of the photovoltaic module, reduces the occurrence of microcracks or even fragments in the photovoltaic module, and saves costs.

[0036] like Figures 1-6As shown, the photovoltaic module with support mainly includes a front glass 100, a front encapsulant film 200, a solar cell 300, a back encapsulant film 400, and a back sheet 500 connected in sequence. Multiple supports 600 are provided on the outer edge of the solar cell layer, and the supports 600 are located between the front glass 100 and the back sheet 500. One end of the support 600 abuts against the front glass 100, and / or the other end of the support 600 abuts against the back sheet 500.

[0037] Based on the above design, the support body 600 is configured such that one end of the support body 600 abuts against the front glass 100, or the other end of the support body 600 abuts against the back panel 500, or one end of the support body 600 abuts against the front glass 100 while the other end of the support body 600 abuts against the back panel 500. The support body 600 provides support to the edges of the photovoltaic module with the support body, preventing unstable edge adhesive overflow during the lamination process and allowing the edges of the photovoltaic module with the support body to accommodate as much adhesive film (molten state) as possible. Simultaneously, it effectively prevents bending deformation of the photovoltaic module with the support body during lamination due to uneven stress at the edges, reducing the likelihood of microcracks or even fragmentation, thus saving costs.

[0038] Furthermore, to improve the stability and reliability of the support 600, in this embodiment, one end of the support 600 passes through the front adhesive film 200 and abuts against the front glass 100, while the other end of the support 600 passes through the back adhesive film 400 and abuts against the back plate 500. This achieves the fixing effect on the support 600, preventing relative slippage of the support 600 and improving stability.

[0039] Understandably, in the lamination process, the support 600 is bonded to the front glass 100 at one end that passes through the front adhesive film 200, and to the back panel 500 at one end that passes through the back adhesive film 400.

[0040] Optionally, the multiple supports 600 in this embodiment can be arranged continuously or at equal intervals, thereby enabling the multiple supports 600 to be flexibly arranged and improving flexibility, applicability and compatibility.

[0041] like Figures 1-2 As shown, in this embodiment, the support 600 includes a body 610 and a support foot 620. One end of the support foot 620 is connected to the periphery of the body 610, and the other end passes through the front adhesive film 200 and is connected to the front glass 100. The support foot 620 can be inserted into the front adhesive film 200, thereby improving the relative stability between the support 600 and the front adhesive film 200 and preventing the support 600 from sliding relative to each other.

[0042] Optionally, in this embodiment, multiple support feet 620 are provided, and the multiple support feet 620 are evenly arranged about the axis of the main body 610. This can improve the stability and reliability of the support body 600, avoid displacement such as tipping over, and improve product yield.

[0043] For example, the number of support feet 620 in this embodiment can be set to 3, 4, 5, 6, etc.

[0044] In actual operation, the operator pre-drills holes in both the front adhesive film 200 and the back adhesive film 400. Then, before the lamination process, the operator inserts each support 600 through the corresponding hole between the front adhesive film 200 and the back adhesive film 400. In other words, in this embodiment, the support 600 passes through the back adhesive film 400 and the front adhesive film 200 sequentially from top to bottom. This way, the installation of the support 600 can be completed in one operation, improving work efficiency and saving time and effort.

[0045] like Figures 1-3 As shown, in this embodiment, the bottom of the body 610 is conical, and the bottom of the body 610 passes through and is accommodated within the front adhesive film 200. This increases the contact area between the body 610 and the front adhesive film 200, thereby improving the stability of the support 600 and reducing the phenomenon of the support 600 sliding.

[0046] For example, the vertical height distance between the bottom of the body 610 and the bottom of the support foot 620 is set to 0.05mm-0.5mm, which allows the bottom of the body 610 to be accommodated in the front adhesive film 200, thus avoiding penetration of the front adhesive film 200.

[0047] Optionally, the body 610 in this embodiment can be cylindrical, with a height of 0.1mm-0.8mm and a diameter of 1mm-10mm. Of course, operators can flexibly set the shape and size of the body 610 according to actual needs, which will not be elaborated further here.

[0048] like Figures 1-2 As shown, in this embodiment, a suction cup 630 is provided on the top of the main body 610. The suction cup 630 passes through the back adhesive film 400 and is adsorbed onto the back plate 500. The suction cup 630 increases the adsorption force between the support 600 and the back plate 500, further improving the stability and reliability of the connection between the support 600 and the back plate 500, and reducing the phenomenon of slippage of the support 600.

[0049] For example, the depth of the suction cup 630 can be set between 0.05mm and 0.2mm, and the diameter of the suction cup 630 can be set between 1.2mm and 10.2mm.

[0050] In some alternative implementations, such as Figure 5 As shown, the top of the main body 610 is provided with multiple protrusions 640, which are evenly arranged and connected to the back plate 500. The protrusions 640 can increase the friction between the support body 600 and the back plate 500, reduce the slippage of the support body 600, and improve stability.

[0051] Optionally, in this embodiment, the body 610, suction cup 630, and support foot 620 are integrally formed, improving processing efficiency and saving costs. Similarly, the body 610, protrusion 640, and support foot 620 can also be integrally formed.

[0052] Optionally, the support 600 in this embodiment includes a rubber component; in other words, the support 600 can be made of rubber material to reduce costs. For example, the support 600 in this embodiment can be made of highly transparent ethylene propylene rubber, ethylene-vinyl acetate, chlorohydrin rubber, butyl rubber, etc. These materials have good high-temperature resistance, allowing the support 600 to maintain its original shape and not melt during lamination.

[0053] Of course, in some alternative embodiments, the support 600 can also be made of a molten material. It should be noted that the high temperature resistance of the molten material is stronger than that of the front film 200 and the back film 400. In this way, during the lamination process, the flow properties of the support 600 are less than those of the front film 200 and the back film 400, so as to ensure that the support 600 can provide a certain support force at the edge of the photovoltaic module with the support.

[0054] Optionally, in this embodiment, the backplate 500 is a back glass and the solar cell 300 is a double-sided solar cell, thereby assembling a double-glass photovoltaic module with a support structure to improve power generation efficiency and save costs.
