[0002] Photovoltaic tiles are a new type of building material that combines solar photovoltaic modules with building tiles. As an innovative green building material, photovoltaic tiles provide a new solution for achieving building energy conservation and sustainable development.

[0003] Conventional photovoltaic module products currently have front and back panels made of glass or glass for the front panel and polymer for the back panel, which cannot be further processed. When the back panel cannot be further processed, it is impossible to obtain the desired shape on site. Utility Model Content

[0004] In view of the problems in the prior art, the utility model provides a photovoltaic tile assembly with a multi-layer structure.

[0005] The technical solution adopted by the utility model to solve its technical problems is: a multi-layer photovoltaic tile assembly, including a backboard, a glass plate adhered to the backboard by glue, the length and width of the glass plate are smaller than the length and width of the backboard, and an overflow glue groove is provided on the backboard, and the overflow glue groove is used to receive the glue flowing out when the glass plate is adhered; an adhesive film is provided on the inner side of the glass plate, a battery cell is provided on one side of the adhesive film, and an adhesive film is provided on the other side of the battery cell.

[0006] An adhesive film is provided on the inner side of the back plate, an insulating film is provided on one side of the adhesive film, and an adhesive film is provided on the other side of the insulating film, and one side of the adhesive film is attached to the battery cell.

[0007] The output end of the battery cell is connected to a wiring terminal, and a connecting wire is provided on the wiring terminal.

[0008] Beneficial effects:

[0009] 1. Through the redesign of the interlayer structure of the front glass and back metal materials, the back panel can be further processed when needed to obtain the required shape for application in the actual site without the need to modify the existing site.

[0010] 2. Due to the characteristics of the back sheet being a galvanized magnesium aluminum sheet, this type of photovoltaic module can be re-processed into a shape that fits the actual roof color steel tiles, making it easier to install on site; reducing the use of installation components and improving installation efficiency.

[0016] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0017] In one embodiment, please refer to the appendix of the specification. Figure 1-3 As shown, the utility model describes a multi-layer photovoltaic tile assembly, comprising a backboard 1, to which a glass plate 2 is bonded by glue, wherein the length and width of the glass plate 2 are smaller than those of the backboard 1, and a glue overflow groove 3 is provided on the backboard 1, wherein the glue overflow groove 3 is used to receive glue flowing out when the glass plate 2 is bonded; an adhesive film 7 is provided on the inner side of the glass plate 2, a battery cell 4 is provided on one side of the adhesive film 7, and an adhesive film 7 is provided on the other side of the battery cell 4.

[0018] The back panel 1 material is changed from glass to zinc-magnesium-aluminum plate, and the dimensions of the plate glass are 100-200mm larger on all sides to facilitate later processing. Furthermore, the glass plate 2 is heat-strengthened glass; and the adhesive film 7 is EVA film 7.

[0019] An adhesive film 7 is provided on the inner side of the back plate 1 , an insulating film 8 is provided on one side of the adhesive film 7 , and another adhesive film 7 is provided on the other side of the insulating film 8 . One side of the adhesive film 7 is bonded to the battery cell 4 .

[0020] The insulating film 8 adopts PET insulating film 8, and the PET insulating film 8 and the third layer of EVA film 7 are added to the layer structure. Since the backboard 1 is a metal material, there is a possibility of conductivity when used in a photovoltaic module, so the PET insulating film 8 is used to effectively isolate the battery cell 4 from the metal. Since adhesion is required, an EVA film 7 is added between the PET insulating film 8 and the metal backboard 1 to make the two tightly combined.

[0021] The output end of the battery cell 4 is connected to a terminal 5 , and a connecting wire 6 is provided on the terminal 5 .

[0022] Production process control: Compared with conventional photovoltaic products, the cell 4 needs to be arranged with the front side facing upward during production. Because the size of the glass plate 2 is smaller than the back plate 1, the cell 4 facing upward facilitates observability during the final assembly. At the same time, measures need to be taken to fix the glass plate 2 on the back plate 1 to prevent the glass plate 2 from moving during lamination.

[0023] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention. The scope of protection claimed in the present invention is defined by the appended claims and their equivalents.
