To reach above-mentioned purpose, the technical solution adopted for the present invention to solve the technical problems is：
A kind of film for photovoltaic module, from down to up including adhesive linkage and pet layer, the film is only used for covering photovoltaic group
Region on welding and/or photovoltaic module on part between each cell piece.
After welding is covered using the film of the present invention, then EVA encapsulation is carried out, due to there is PET to play buffer action, on welding
Film of flux residue will not with encapsulation EVA directly contact, the chemical reaction thoroughly prevented between the two bring it is bad after
Fruit.
Preferably, the pet layer is black or the parameters of RGB tri- are equal to or the color less than 10.Using black PET, subtract
The light reflectivity of few component, reduce pollution of the dazzle to environment.
Preferably, the pet layer includes basic unit and surface layer, and the surface layer is that black or the parameters of RGB tri- are equal to or be less than
10 color.
Preferably, the surface layer has some micropores, and transparent intermediate layer is additionally provided between the basic unit and surface layer, described
The one side of basic unit and intermediate layer contact is coated with reflector layer.
Preferably, the micropore is arranged according to rule.
In certain embodiments, length direction rule arrangement of the every group of micropore along reflectance coating.For example, arranged by matrix, or
Person's dislocation is continued in all directions or two sides continuously arrangement etc..Wherein, according to different different regions latitudes, according to the incidence of sunlight
Angle, the axis of every group of micropore and the angle on pet layer surface are suitably adjusted, meanwhile, to two sides of prism in basic unit
Angle be adjusted correspondingly, it is possible to sunlight is reflexed to the working region of cell piece, wherein, difference group micropores axle
Line can be different from the angle of PEY layer surfaces, e.g. in periodically variable, to meet to the morning, noon, afternoon not
Reflection with sunlight needs.For example, further, vertical micropore can be made funnel shaped, there is facing surface in its aperture
Lower bottom is gradually reduced, and can so improve it and import the scope of sunlight.Using this programme, can both be carried with reflecting part sunlight
The utilization ratio of high sunlight, while the rigors to dazzle pollution can be met again, meet the needs of different application occasion.
In the surface layer of pet layer, some micropores are set, for example, arranged according to matrix, text profile arrangement or it is other it is regular,
Periodic arrangement, sunlight had both eliminated dazzle pollution, with regard to that can bring aesthetic feeling by the reflected light such as starbright of these micropores.
Preferably, the micropore is arranged in groups, and every group of micropore includes a vertical micropore and each one of left and right leans outward
Oblique micropore.
Preferably, the basic unit is provided with microprism, and below every group of micropore, the crest line of the microprism is positioned at vertical
The underface of straight micropore, two side are vertical with the axis of two outward-dipping micropores respectively.
Communicated between every group of micropore in bottom, therefore, the sunlight incident from any micropore all may be from other micro-
Reflected away in hole.When setting microprism under vertical micropore, the sunlight of noon vertical incidence is only capable of from vertical micropore
Inject, then gone out by two sides of microprism from two inclined micro-voided reflectives, the sunlight reflected away is by encapsulation glass
The secondary reflection again of glass, the working region of cell piece can be irradiated to, so, both eliminate dazzle pollution, and improved the profit of sunlight again
With rate, the solar energy conversion efficiency of whole photovoltaic module is improved.
The present invention also provides a kind of photovoltaic module, including back board module, framework, glass panel, multiple cell pieces, is connected to
The welding on cell piece surface and any of the above-described described film for photovoltaic module, the film is covered on welding and/or photovoltaic

Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other under the premise of creative work is not made
Embodiment, belong to the scope of protection of the invention.
In order to reach the purpose of the present invention, as shown in figure 1, a kind of film for photovoltaic module, includes bonding from down to up
Layer 2 and pet layer 1, the film are only used for covering the area on the welding and/or photovoltaic module on photovoltaic module between each cell piece
Domain.
After welding is covered using the film of the present invention, then EVA encapsulation is carried out, due to there is pet layer to play buffer action, welding
On film of flux residue will not with encapsulation EVA directly contact, the chemical reaction thoroughly prevented between the two brings bad
Consequence.Adhesive linkage can be PUR coating or other adhesive coatings.
In certain embodiments, in order to further obtain low dazzle characteristic, the pet layer is that black or the parameters of RGB tri- are equal
Color equal to or less than 10.Using black PET, the light reflectivity of component is reduced, reduces pollution of the dazzle to environment.
In certain embodiments, the pet layer includes basic unit and surface layer, and the surface layer is that black or the parameters of RGB tri- are impartial
In or less than 10 color.

Directly.
Communicated between every group of micropore in bottom, therefore, the sunlight incident from any micropore all may be from other micro-
Reflected away in hole.When in vertical 111 times setting microprisms 121 of micropore, the sunlight of noon vertical incidence is only capable of from vertical
Injected in micropore 111, then reflected away, reflect away from two inclined micropores 112 by two sides of microprism 121
Sunlight passes through the secondary reflection again of packaged glass, can be irradiated to the working region of cell piece, so, has both eliminated dazzle pollution, again
The utilization rate of sunlight is improved, improves the solar energy conversion efficiency of whole photovoltaic module.
Wherein, the angle change that sunlight comes through the refractive band of intermediate layer 13 is, it is necessary to count, finally to determine that inclination is micro-
The angle in hole 112.
If polyhedral cone shaped microprism is provided that below every group of micropore, and per one side not with vertical micropore
Vertical plane where axis is orthogonal (i.e. any straight line perpendicular to certain one side, not on the vertical plane).Now, tilt micro-
The quantity in hole is identical with the side quantity of microprism, and its inclination angle is determined by the angle of corresponding side surface, the refractive index in intermediate layer,
As long as ensuring by the incident sunshine of vertical micropore, by each offside reflection of taper microprism, the inclination as corresponding to each side
Micropore projects.
