Technical field
The utility model relates to a kind of glass, particularly a kind of coated glass that has diaphragm.The utility model mainly is applicable to used for packaging solar battery assembly glass.The utility model belongs to solar components and makes production technical field.
Background technology
Along with increasingly sharpening of energy crisis and environmental pollution, the photovoltaic generation industry is paid much attention in worldwide and is developed rapidly.The guiding direction of photovoltaic generation is to raise the efficiency and reduce cost, and the two is to be mutually related.At present, single crystal silicon solar cell sheet efficient can reach 24%, and polycrystalline silicon solar cell sheet efficient can reach 18%, and amorphous silicon solar cell sheet efficient is 6%～8%, all relatively near its theoretical value.The efficient difficulty that improves later on the battery sheet again is bigger, and therefore, increasing the assembly generating efficiency through the light transmittance that increases EVA, glass is a kind of simple and effective and approach that potentiality are bigger.
Coatings (AR film through plating antireflective film on the solar cell packaged glass; Also claim anti-reflection film), form anti-reflection antireflective coated glass, can effectively reduce glass surface to visible reflection of light; Increase the transmitance of sunlight, thereby effectively improve the generating efficiency of solar cell.
Coated glass production at present generally is directly to be deposited in together after accomplishing, and perhaps packing paper is isolated, and the coated glass surface stays finger mark easily or makes moist and stays the paper seal, has increased assembly surface greatly and has cleaned difficulty.In addition; In assembly production, carry out in the processes such as high temperature lamination, assembly surface cleaning; Through regular meeting take place that coated glass surface coating layer is damaged by the EVA of tetrafluoro cloth remained on surface bonding in the high temperature lamination, in the operation that framing up by silica gel pollute, in matting by various phenomenons such as hard thing scuffing such as blades, be very crucial problem so how effectively to protect the coated glass surface not to be damaged.
Publication number is that the Chinese patent of CN201667338 U discloses the encapsulation of a kind of solar module and uses the coated glass protective device, and this device comprises the PET film, and this PET film is attached to the surface of coated glass, and the area of the PET film on described is less than the area of coated glass.This device is protected the coated glass surface through the PET film.But the coated glass of this structure but exists following defective: (1) this PET film covers on glass insecure, comes off easily, and pad pasting efficient is low, and the pad pasting weak effect is wasted time and energy; (2) this PET film thickness is selected 15 nm～25nm for use, and the PET film thickness is too thin, and production cost is high, and can not effectively protect the coated glass superficial film.Therefore, the self-shield of coated glass is still a technical barrier that urgency is to be solved.
Summary of the invention
The purpose of the utility model is the deficiency to prior art, and a kind of simple in structure, difficult drop-off, pad pasting efficient is high, cost of manufacture is low, protection the is effective coated glass that has diaphragm are provided.
The technical scheme that realizes above-mentioned purpose is: a kind of coated glass that has diaphragm; The coated glass that is coated with coatings by the surface is formed; On the surface of coatings, also be pasted with diaphragm, described diaphragm is the PET film, and the PET film attaches through static and is fixed on the surface of coatings.
Further, also be provided with adhesive tape, adhesive tape is arranged on the periphery of PET film and coated glass and the two is fixed.
Further, the thickness of said PET film is 1 μ m～100 μ m.
Further, said PET film is to adopt laser or blade to cut film production by the PET film of continuous spool structure to form.
Further, surperficial length and the width with the coated glass surface of described PET film all equates; Perhaps the length on PET film surface and width are all less than the length and the width on coated glass surface, and the edge of PET film and the Edge Distance of coated glass are 7 mm～15mm.
Further, described PET film attaches through the static that adds the electrostatic equipment generation and is fixed on the surface of coatings.
After adopting technique scheme, the utlity model has following beneficial effect:
(1) diaphragm of the utility model is PET film (the PET film has another name called the high temperature resistance polyester film); The PET film attaches through static and is fixed on the surface of coatings, and absorption property is good, and PET film and coated glass attach fixing very firm; Difficult drop-off; And simple in structure, pad pasting efficient is high, protects effective.
(2) the utility model also is provided with adhesive tape (4); Adhesive tape (4) is arranged on the periphery of PET film (3) and coated glass (1) and the two is fixed; Further improve the attaching fixation degree of PET film and coated glass, make the utility model fixing more solid and reliable.
(3) thickness of the utility model PET film is 1 μ m～100 μ m; Thickness is improved to micron order by the nanoscale of prior art, and the thickness of PET film is thickened, and can make the enhancing anti-wear performance on the one hand; Make the protection of PET film protection plated film effective, defencive function is more powerful; Cost of manufacture reduces greatly on the other hand, and is applicable in the coated glass assembly of different size and is widely used, and the scope of application is wide.
(4) the utility model PET film is to adopt laser or blade to cut film production by the PET film of continuous spool structure to form; Cost of manufacture is low; Can protect the integrality of coated glass surface coating layer effectively according to the area of any any PET film of intercepting of coated glass size simultaneously.
(5) the utility model PET film can prevent effectively that the coated glass surface from staying finger mark, paper seal etc.; The fusing point of this PET film is more than 260 ℃, and the component lamination temperature so prevents PET film high-temp. fusing bonding in the use between 135 ℃～150 ℃, thereby destroy the problem of surfacing superficial film, so the utility model security protection performance is higher.
(6) the utility model PET film sheet operation under the Coated Glass Line begins; In the transportation of coated glass, deposit in all links of process and whole solar module encapsulation process and be attached to the coated glass surface always, this PET film-strength is higher, is difficult for being destroyed; The PET film of before testing, only need tearing gets final product; Need not partly clean glass surface, thereby effectively save scavenging period, practice thrift the use cost that alcohol, erasing rubber, rag etc. clean material simultaneously; Not only improve cleaning efficiency, and saved the cleaning cost.
