Description
Technical field
The utility model relates to a kind of technical field of solar cell, especially a kind of solar battery back film.
Background technology
Flourish along with solar cell industry more and more is subject to industry as the backboard membrane of one of encapsulating material that is applied to solar cell and pays close attention to.Topmost solar module as the solar photoelectric utilization is to be formed by the vacuum heat seal by high efficiency crystalline silicon solar cell, ultrawhite woven design toughened glass, EVA, crystalline silicon and notacoria, and notacoria plays a part skeleton and the crystal silicon body is protected.Existing solar battery back film water resistance is poor, and cell piece is easily distortion in use, has shortened the useful life of solar cell.
The utility model content
In order to overcome the deficiency that existing solar battery back film water proofing property is poor, yielding and useful life is short, the utility model provides a kind of solar battery back film.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of solar battery back film, comprise PVC basic unit, polymethyl methacrylate, fluorine carbon film layer and back-up coat, be covered with one deck polymethyl methacrylate in PVC basic unit, be provided with back-up coat between PVC basic unit and fluorine carbon film layer.
According to another embodiment of the present utility model, comprise that further described back-up coat is woven mesh layer.
The beneficial effects of the utility model are that this solar battery back film is simple in structure, compact and reasonable, and is easy to assembly quick, connect reliable, reduced the water absorption of cell piece, corrosion resistance is higher, and electric insulating quality is good, cell piece is not yielding, good stability of the dimension, cell piece has stronger shock resistance simultaneously, has extended the useful life of solar cell, greatly improved the reliability of solar cell working, be easy to use and promote.
Description of drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
1.PVC basic unit in figure, 2. polymethyl methacrylate, 3. fluorine carbon film layer, 4. back-up coat.
Embodiment
Structural representation of the present utility model as Fig. 1, a kind of solar battery back film, comprise PVC basic unit 1, polymethyl methacrylate 2, fluorine carbon film layer 3 and back-up coat 4, be covered with one deck polymethyl methacrylate 2 in PVC basic unit 1, be provided with back-up coat 4 between PVC basic unit 1 and fluorine carbon film layer 3, described back-up coat 4 is woven mesh layer.
During use, be covered with one deck polymethyl methacrylate 2 in PVC basic unit 1, strengthened the electric insulating quality of notacoria, be covered with one deck fluorine carbon film layer 3 on PVC basic unit 1 lower surface, be provided with back-up coat 4 between PVC basic unit 1 and fluorine carbon film layer 3, described back-up coat 4 is woven mesh layer, mesh grid is fitted between PVC basic unit 1 and fluorine carbon film layer 3 by adhesive, then fluorocarbon coating is directly applied on back-up coat 4, just direct formation of film at surface on back-up coat 4 again, saved adhesive and be difficult for delamination.This solar battery back film is simple in structure, compact and reasonable, easy to assembly quick, connect reliably, reduced the water absorption of cell piece, corrosion resistance is higher, electric insulating quality is good, and cell piece is not yielding, good stability of the dimension, cell piece has stronger shock resistance simultaneously, extended the useful life of solar cell, greatly improved the reliability of solar cell working, be easy to use and promote.
