Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the invention, as detailed in the appended claims.
As shown in fig. 1, the light flexible photovoltaic module provided by the invention comprises a TFB film layer 1, a water-blocking film layer 2, a composite glass fiber layer 3, a battery string 4 and an FFC double-sided fluorine-containing back film layer 5 in sequence from top to bottom, wherein the TFB film layer 1 and the water-blocking film layer 2, the water-blocking film layer 2 and the composite glass fiber layer 3, the composite glass fiber layer 3 and the battery string 4, and the battery string 4 and the FFC double-sided fluorine-containing back film layer 5 are connected through an EVA film 6; coating liquid is sprayed on one side, far away from the water blocking film layer 2, of the TFB film layer 1, and the water blocking film layer 2 sequentially comprises an EVA adhesive layer, a PET film layer, a high barrier layer, a PE protective layer and an EVA adhesive layer from top to bottom.
The TFB film layer sequentially comprises an outer protection layer PVF, a middle layer PET and a fluorine-containing bonding layer from top to bottom.
(1) Outer protective layer PVF — weatherable layer: in order to make the photovoltaic module have good weather resistance, the outer layer material is generally required to contain fluorine, and PVF and PVDF are two well-known weather-resistant high polymer materials, because the C-F bond energy in the outer layer material is 485KJ/mol, the bond energy in organic compound covalent bonds is the largest, only photons with the wavelength less than 220nm can dissociate the C-F bond, and in sunlight, the photons with the wavelength less than 220nm only account for less than 5%, and the few photons with the wavelength less than 220nm are easily absorbed by an ozone layer and can reach the ground very rarely. Therefore, the weather resistance of the photovoltaic module can be greatly improved by providing the PVF protective layer on the outermost layer of the photovoltaic module.
(2) Middle layer PET: the composite material has the advantages of supporting function, high and low temperature resistance, stable mechanical property, excellent electrical insulation, favorable creep resistance, fatigue resistance, friction resistance and dimensional stability, and low gas and steam permeability.
(3) A fluorine-containing bonding layer: since unmodified fluorine-containing films and PET have poor adhesion to EVA, it is necessary to use modified fluorine-containing materials or EVA, PE, and PA films having strong adhesion.
According to the light flexible photovoltaic module, the cover plate of the conventional photovoltaic module is replaced by glass to form the TFB film layer in the application, and the coating liquid is sprayed on one side, far away from the composite glass fiber layer, of the TFB film layer, so that the weight of the photovoltaic module is reduced, the photovoltaic module is flexible and can be installed on a curved roof; the coating liquid can fill pits on the TFB film layer, so that the side, in contact with the outside, of the TFB film layer becomes flat and smooth, the light permeability increasing performance is improved, and the optical permeability of the cover plate is increased to be more than 2%; the PET rete in the water blocking film can reduce surface energy, reduces the adhesion of dust, makes the dust take away easily by wind, and can effectively prevent water vapor permeation.
And, flexible photovoltaic module of light in this application need not to use the installing support to install when the installation, only needs to install the adhesive tape on the installation face, can realize photovoltaic module's installation, and its mounted position is unrestricted, and because photovoltaic module's weight reduces to 3.5 kg/square meter in this application, consequently, its requirement is less than conventional subassembly requirement far away to the roof bearing.
Preferably, an aluminum foil is arranged on one side, far away from the battery string, of the FFC double-sided fluorine-containing back film layer. In the embodiment, the aluminum foil is arranged on the side, far away from the cell string, of the FFC double-sided fluorine-containing back film layer, so that the back surface of the photovoltaic module can also prevent the permeation of water vapor by 100%.
More preferably, the aluminum foil is electrochemically adhered to the fluorine-containing back film layer on a side thereof remote from the cell string.
Preferably, the coating liquid comprises modified silane, ethanol and an additive. Wherein, the additive is an auxiliary agent which can be water, octanol or a mixture of water and octanol, and the mass percentage of the additive is 1.5-2.5%.
Preferably, the EVA film comprises a main material, a light absorber, a light stabilizer, an antioxidant, and a curing agent.
the light stabilizer is bis (2,2,6, 6-tetramethyl-4-piperidyl) sebacate, the antioxidant is tris (nonylphenyl) phosphite, and the curing agent is 2, 5-dimethyl-2, 5-di-tert-butyl hexane peroxide.
Preferably, the ethylene-vinyl acetate copolymer accounts for 97.8-98% by mass, the 2-hydroxy-4-n-octoxybenzophenone accounts for 0.28-0.32% by mass, the bis (2,2,6, 6-tetramethyl-4-piperidyl) sebacate accounts for 0.08-0.12% by mass, the tris (nonylphenyl) phosphite accounts for 0.18-0.22% by mass, and the 2, 5-dimethyl-2, 5-di-tert-butylperoxyhexane accounts for 1.45-1.55% by mass.
More preferably, the ethylene-vinyl acetate copolymer is 97.9% by mass, the 2-hydroxy-4-n-octoxybenzophenone is 0.3% by mass, the bis (2,2,6, 6-tetramethyl-4-piperidyl) sebacate is 0.1% by mass, the tris (nonylphenyl) phosphite is 0.2% by mass, and the 2, 5-dimethyl-2, 5-di-tert-butylperoxyhexane is 1.5% by mass.
Wherein in the ethylene-vinyl acetate copolymer, the mass percentage of the vinyl acetate is 21%. This example increases the hardness of the PVF film by setting the mass percentage of vinyl acetate in the ethylene-vinyl acetate copolymer to 21%.
Other embodiments of the invention will be apparent to those skilled in the art from consideration of the specification and practice of the disclosure disclosed herein. This application is intended to cover any variations, uses, or adaptations of the invention following, in general, the principles of the invention and including such departures from the present disclosure as come within known or customary practice within the art to which the invention pertains.
