Abstract
The utility model discloses a transparent composite membrane for a rear panel of a solar battery. The transparent composite membrane is characterized by comprising a first polyvinylidene fluoride (PVDF) membrane, a first glue layer, a polyethylene terephthalate (PET) panel, a second glue layer and a second PVDF membrane, wherein the first PVDF membrane is adhered with the PET panel through the first glue layer; and the second PVDF membrane is adhered with the PET panel through the second glue layer. The transparent composite membrane for the rear panel of the solar battery has the advantages that due to the first PVDF membrane and the second PVDF membrane, the weather resistance and the chemical corrosivity of the transparent composite membrane are improved; a battery sheet can be well protected; and the service life of a solar battery module is prolonged.
Description
Technical field
The utility model relates to a kind of transparent solar cell rear panel compound film.
Background technology
The generating of solar module source is the battery sheet in the assembly, will decay rapidly if the battery sheet is not carried out its generated output of packaging protection, thereby the use value of losing, so the life-span of encapsulating material directly influence the life-span of battery component.Develop a series of encapsulating material for reaching permanent instructions for use people, using more at present is compound film for solar battery rear board, though can satisfy the instructions for use of solar cell, its complicated process of preparation, cost is higher.
Compound film for solar battery rear board is big owing to hot strength, elastic modelling quantity is high, impact strength is big, cold-resistant good heat resistance, electrical insulating property are good etc. is widely used in many fields such as industry, civilian, agricultural, and electron trade is higher to its requirement, requires it to have higher hardness; More wear-resistant, scratch resistance is hindered; Pollution resistance is stronger, and now the compound film for solar battery rear board on the market to exist hardness lower, easy to wear; Be prone to scratch, shortcomings such as pollution resistance difference.
The utility model content
The utility model technical problem to be solved be to provide a kind of barrier property good, prolong the solar module transparent solar cell rear panel compound film in service life.
1, a kind of transparent solar cell rear panel compound film; Comprise first pvdf membrane, first glue layer, PET plate, second glue layer and second pvdf membrane; It is characterized in that; First pvdf membrane and PET plate are bonding through first glue layer, and second pvdf membrane and PET plate are bonding through second glue layer.
Preferably, the described first pvdf membrane thickness is 0.05mm-0.25mm.
Preferably, the described first glue layer thickness is 0.005mm-0.02mm.
Preferably, described PET plate is transparent, and thickness is 0.5mm-2.5mm.
Preferably, the described second glue layer thickness is 0.005mm-0.02mm.
Preferably, the described second pvdf membrane thickness is 0.05mm-0.25mm.
A kind of transparent solar cell rear panel compound film of the utility model beneficial effect is:
Being provided with first pvdf membrane and second pvdf membrane strengthens the weatherability of transparent solar cell rear panel compound film and chemical corrosivity; Can better protect the battery sheet, prolong the service life of solar module.
Description of drawings
Fig. 1 is the sectional view of the utility model.
Among the figure: 1-first pvdf membrane, 2-first glue layer, 3-PET plate, 4-second glue layer, 5-second pvdf membrane.
The specific embodiment
Below in conjunction with embodiment and accompanying drawing the utility model is described further, but the protection domain of the utility model is not limited to this.
