Structure, and per layer of surface is all smooth, by bonding agent bonding between adjacent two layers, but with use time by
Step extends, and through the impact of the weather such as hardships rain and dew, the viscosity between upper, middle and lower-ranking can be reduced, due to upper, middle and lower-ranking
It is burnishing surface, is easy to separation occur each other, especially the edge of bonding is easy to occur peeling off tilt, so as to shadow
Ring the performance of photovoltaic cell.
And the both sides of existing photovoltaic back are typically directly exposed to outside, no any protection is of long duration
It is easy to abrasion occur, so can also affects the performance of photovoltaic cell.
In view of above-mentioned defect, the design people, positive research and innovation in addition, to founding a kind of photovoltaic back with bound edge
Plate so as to more the value in industry.
Utility model content
To solve above-mentioned technical problem, the purpose of this utility model is to provide a kind of photovoltaic back with bound edge, Neng Goufang
Only separating occurs in upper, middle and lower-ranking, it is to avoid abrasion occur in the both sides of photovoltaic back, it is ensured that the stability of photovoltaic cell, prolongation make
Use the life-span.
A kind of photovoltaic back with bound edge of the present utility model, including the upper, middle and lower, the upper following table in the middle level
Face is serrated, and the lower surface on the upper strata and the upper surface of lower floor are serrated, the upper surface on the upper strata and lower floor
Lower surface it is flat, the lower surface on the upper strata is engaged with the upper surface in the middle level, the upper surface of the lower floor with
The lower surface engagement in described being in, the engagement between engagement and middle level and lower floor between the upper strata and middle level are interference
Coordinate, between the upper strata and middle level and between middle level and lower floor, pass through tack coat bonding；
Also include glass-film bound edge, the glass-film bound edge is symmetrically coated on two after the upper, middle and lower-ranking is combined
Side, the upper and lower ends of the glass-film bound edge are equipped with boss, and the boss is bonded in the edge of the upper and lower respectively
Part, the mid portion of the glass-film bound edge are bonded on the side wall after the upper, middle and lower-ranking combination.
Further, the thickness of the glass-film bound edge is 10-20 microns.
Further, the thickness of the upper and lower is 20-40 microns.
Further, the thickness in the middle level is 200-400 microns.
Further, the thickness of the tack coat is 4-8 microns.
Further, the upper strata is PEVA layers.
Further, the middle level is pet layer.
Further, the lower floor is PVDF layers.
By such scheme, this utility model at least has advantages below：Photovoltaic back with bound edge of the present utility model
The lower floor that the upper strata and upper surface being serrated with lower surface by the middle level that upper and lower surface is serrated respectively is serrated
Intermeshing, and engagement is interference fit, makes, middle level and in, combine more firmly between lower floor, even if making for a long time
Adhesive effect is lost with rear tack coat, upper, middle and lower-ranking still closely can be combined together, and will not separate, prevent upper, middle and lower
The corner that three-layered node is closed occurs peeling off tilting, it is ensured that photovoltaic cell performance steady in a long-term, increases the service life.
Both sides after glass-film bound edge is symmetrically coated on upper, middle and lower-ranking combination, can play a part of protection,
Avoid the both sides of upper, middle and lower-ranking from being directly exposed to outside, prevent abrasion, while glass-film bound edge also can be to upper, middle and lower three
Abutting edge between layer is protected, and further prevents occurring separation between upper, middle and lower-ranking.
Described above is only the general introduction of technical solutions of the utility model, in order to better understand skill of the present utility model
Art means, and being practiced according to the content of description, with preferred embodiment of the present utility model and coordinate accompanying drawing detailed below
Describe in detail bright as after.
Description of the drawings
Fig. 1 is a kind of structural representation of the photovoltaic back with bound edge of this utility model.
Specific embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below
Embodiment is used to illustrate this utility model, but is not limited to scope of the present utility model.
Embodiment：A kind of photovoltaic back with bound edge, including upper strata 1, middle level 2 and lower floor 3, the upper and lower surface in the middle level
