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 entered
Row is clearly and completely described, it is clear that described embodiment is only a part of embodiment of the invention,
Rather than whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art are not having
There is the every other embodiment obtained on the premise of making creative work, belong to protection of the present invention
Scope.
The invention provides a kind of solar cell module encapsulating structure, including solar battery sheet group 1,
EVA adhesive film 2, low iron safety glass 3, in addition to frame 4, backboard 5, terminal box 6；Low iron steel
Change the laying EVA adhesive film 2 above of glass 3, EVA adhesive film 2 lays solar battery sheet group 1 above,
Solar battery sheet group 1 lays EVA adhesive film 2 above, and EVA adhesive film 2 lays low iron tempering glass above
Wavelength-shifting agent is mixed with glass 3, the low backboard 5 installed above of iron safety glass 3, EVA adhesive film, it is described
