Abstract
The utility model relates to a coated glass protective device used for packaging a solar cell module. The device comprises a PET film that is pasted on the surface of a piece of coated glass, wherein the area of the PET film is less than that of the coated glass. Compared with the prior art, the coated glass protective device has the advantages of wide application scope, strong practicability, high safety performance, high efficiency, low cost and the like.
Description
Technical field
The utility model relates to solar components, especially relates to a kind of solar module encapsulation coated glass protective device.
Background technology
After entering the seventies, because the influence of secondary oil crisis, photovoltaic generation is worldwide paid much attention to, and develops very fast.In the long run, photovoltaic generation will enter electricity market with decentralized power supply, and part replaces conventional energy resource.With regard to photovoltaic module self generating amount, depend primarily on the photoelectric conversion efficiency of used crystal silicon cell sheet, single crystal silicon solar cell efficient was 20% in 1980, polycrystalline silicon solar cell is 14.5%, single crystal silicon solar cell efficient brought up to 25% in 1998,5 percentage points have been improved in the period of 8, and every backward raising one percentage point all is very difficult, so except that continuing to improve the battery efficiency, increasing the assembly energy output by the light transmittance that increases EVA, glass also is a kind of very feasible approach.
Improve light transmittance=raising assembly energy output.
The method that generally adopts in the industry is that the antireflective coating (AR) that increases one deck nanostructure on the toughened glass surface also claims to increase transmission film at present, mainly form by silica (SiO), thickness is between 70nm to 250nm, this tunic structure is logical to be to absorb the interior solar ultraviolet of multiband, increase the assembly energy output with the secondary reflection principle that reaches after increasing the glass light transmittance and reducing light simultaneously and inject, be called coated glass.In assembly production, need to carry out links such as high temperature lamination, assembly surface cleaning; therefore the coated glass surface anti-reflection film is in high temperature lamination operation; rete often takes place to be damaged by the EVA of tetrafluoro cloth remained on surface bonding; silica gel is seriously polluted to glass surface in the operation that frames up; hard thing such as blade destroys the scuffing of rete in the back road matting; so in coated glass was used, how effectively protecting its surface anti-reflection film not to be damaged was very crucial difficult problem during coated glass is used.
Summary of the invention
The purpose of this utility model is exactly to provide a kind of scope of application wide, practical solar module encapsulation coated glass protective device for the defective that overcomes above-mentioned prior art existence.
The purpose of this utility model can be achieved through the following technical solutions:
The coated glass protective device is used in a kind of solar module encapsulation, it is characterized in that this device comprises the PET film, and this PET film is attached to the surface of coated glass, and the area of described PET film is less than the area of coated glass.
Described PET film thickness is 15～25nm.
The edge of described PET film and the Edge Distance of coated glass are 10～12mm.
Compared with prior art, the utlity model has following advantage:
1, the scope of application is extensively practical: this layer PET film thickness is 20nm; with low cost; can extensive use in the coated glass assembly of different size; in the production effective protection the integrality of coated glass surface anti-reflection film, make the performance of coated glass aspect the lifting subassembly energy output unaffected.
2, security performance height: the PET fusing point is at 255～260 ℃, and the component lamination temperature in use need not be considered the risk of PET film high-temp. fusing bond damage coated glass surface anti-reflection film between 135～150 ℃.
3, raise the efficiency and reduce cost: this layer PET film is from first working procedure, be attached to assembly surface in all links of module testing to the end always, so later process need not partly be cleaned glass surface, save scavenging period greatly, saved the cost of cleaning materials such as alcohol, erasing rubber, rag simultaneously.
Description of drawings
Fig. 1 is the structural representation of a kind of solar module encapsulation of the present utility model with the coated glass protective device.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Embodiment
As shown in Figure 1, the coated glass protective device is used in a kind of solar module encapsulation, and this device comprises PET film 1, and this PET film 1 is attached to the surface of coated glass 2, and the area of described PET film 1 is less than the area of coated glass 2.Described PET film 1 thickness is 15～25nm.The Edge Distance of the edge of described PET film 1 and coated glass 2 is 10～12mm.
Effective protection that 1 pair of coated glass of this layer PET film is 2 layers begins to finish before module testing from first procedure that glass uses.Coated glass 2 laminar surfaces can not be subjected to the pollution and the bond damage of adhesive material such as EVA, silica gel in component lamination frames up process, dispense cleaning in the matting to coated glass 2 surface portions, improved cleaning efficient and quality greatly, the top layer PET film 1 of only need tearing before the test gets final product.And the PET fusing point is at 255～260 ℃, and the component lamination temperature is between 135～150 ℃, so need not consider the problem of PET film high-temp. fusing in component lamination.
