TECHNICAL FIELD

[0001] The present application relates to the field of photovoltaics, in particular to a ceiling photovoltaic module with a colored adhesive film. BACKGROUND

[0002] With the development of photovoltaic technology, the more subdivided BIPV field, namely Building Integrated PV, is also rapidly developed, which is a technology of integrating solar power generation (photovoltaic) products into buildings. However, the colors of the components of the conventional solar power generation (photovoltaic) products are not uniform, and they are directly built on the buildings, which are visually very inconsistent and not very beautiful.

[0003] Therefore, it is necessary to develop a solar power generation (photovoltaic) product that can be integrated with buildings and even can decorate the buildings, while the solar power generation (photovoltaic) product still has high power generation. CONTENT OF THE INVENTION

[0004] The present application provides a new ceiling photovoltaic module, which has a colored adhesive film inside, the colored adhesive film includes a white layer and a colored layer, the colored layer can integrate the ceiling photovoltaic module with the building, and can also decorate the interior of the building, and the white layer can reflect light, so that the ceiling photovoltaic module still has high power generation.

[0005] The present application provides a ceiling photovoltaic module, which adopts the technical means including at least one group of cells, a colored adhesive film closely attached to at least one side of the cells, and glass closely attached to the colored adhesive film, the colored adhesive film includes: at least one white layer; and

[0006] a colored layer closely attached to the white layer, the colored layer has a single color or a plurality of colors irregularly distributed, so that the ceiling has a decorative effect through the colored layer.

[0007] In the ceiling photovoltaic module provided by the present application, the pre-crosslinking degree of the white layer is 10-40%.

[0008] In the ceiling photovoltaic module provided by the present application, the reflectivity of the white layer is 50%-90%.

[0009] In the ceiling photovoltaic module provided by the present application, the thickness of the colored layer is 50-200mm.

[0010] In the ceiling photovoltaic module provided by the present application, the white layer and the colored layer are independently selected from one of EVA, POE, POP, PVB, PP, EAA, SEBS, PE, EMA, and EMMA. BRIEF DESCRIPTION OF DRAWINGS

[0011] Figure 1is a schematic view of an embodiment of the present application. DETAILED DESCRIPTION

[0012] The present application is further described in detail by the following drawings.

[0013] It is particularly noted that:

[0014] EVA: English abbreviation of ethylene-vinyl acetate copolymer;

[0015] POE: English abbreviation of ethylene-butene copolymer or ethylene-octene copolymer;

[0016] POP: English abbreviation of polyvinyl polymer grafted polyether polyol;

[0017] PVB: English abbreviation of polyvinyl butyral;

[0018] PP: English abbreviation of polypropylene;

[0019] EAA: English abbreviation of ethylene acrylic acid copolymer;

[0020] SEBS: English abbreviation of linear tri-block copolymer with polystyrene as end block and ethylene-butene copolymer obtained by hydrogenation of polybutadiene as middle elastic block;

[0021] PE: English abbreviation of polyethylene;

[0022] EMA: English abbreviation of ethylene-methyl acrylic acid copolymer;

[0023] EMMA: English abbreviation of ethylene-methyl methacrylate copolymer.

[0024] Please refer to Figure 1 shown, wherein a schematic view of a roof photovoltaic module provided by the present application is shown; wherein it can be seen that the roof photovoltaic module provided by the present application has a group of cells 10, a color adhesive film 20 closely adhered to at least one side of the cells 10, and a glass 30 closely adhered to the color adhesive film 20; and the color adhesive film 20 includes at least one white layer 21 and a color layer 22 closely combined with the white layer 21, and the color layer 22 has a single color or a plurality of colors irregularly distributed. As can be seen from the figure, the white layer 21 is closely combined with the color layer 22, and the color layer 22 is closely combined with the glass 30, so that the color can only be displayed from the glass side, thereby achieving the effect of decoration and even decoration of the building.

[0025] The color glaze glass is used in the prior art to realize the decoration of the building, the color glaze presents the color haze, the frosted feeling is too heavy, the sense is relatively heavy, and is more suitable for wall decoration, rather than ceiling decoration. Compared with the prior art, the color film is used in the application, the color presented is more transparent, and the open, bright place is more suitable for decoration.

[0026] Preferably, the pre-crosslinking degree of the white layer 21 is 10-40%. In this way, the white layer 21 can be prevented from flowing and shielding the battery 10 when the assembly is laminated, so as to affect the power generation efficiency of the battery 10.

[0027] Preferably, the reflectivity of the white layer 21 is 50%-90%. In this way, the light irradiated at the gap of the battery 10 can be reflected back to be absorbed by the battery 10, so as to provide the power generation efficiency of the battery 10.

[0028] Preferably, the thickness of the color layer 22 is 50-200mm.

[0029] Preferably, the white layer and the color layer are independently selected from one of EVA, POE, POP, PVB, PP, EAA, SEBS, PE, EMA, and EMMA.

[0030] The above are preferred embodiments of the application, and do not limit the protection scope of the application, so: any equivalent changes made according to the structure, shape, principle of the application should be covered within the protection scope of the application.
