The method is simple, and energy consumption is low. The invention further discloses a double-side coating device adopting the method for manufacturing the double-side fluorine back film of the solar cell. By the aid of the device, thicknesses of the fluorine layers on the two sides of the PET (polyester) base layer are uniform, and the thicknesses of the fluorine layers are adjustable.
Description
Technical field
The present invention relates to the preparing technical field of solar elements, especially relate to two-sided fluorine-containing notacoria production method of a kind of solar cell and dual coated device thereof.
Background technology
The quality of solar battery back film is for service life of solar cell for the length, and is very important.When electric property, deadening and the weather resistance of notacoria was not high, solar cell used after several years, and bad phenomenon can appear in the part assembly, has a strong impact on the serviceability and the life-span of assembly.Usually, notacoria is divided into fluorine-containing notacoria and not fluorine-containing notacoria, and fluorine-containing notacoria can be divided into two-sided fluorine-containing notacoria (like TPT) and the fluorine-containing notacoria of single face (like TPE).And the production of two-sided fluorine-containing notacoria has three kinds of technologies usually, the one, directly the PVDF film is compound on the PET base material.The 2nd, rubbing method, with the solution coat of fluoride to the PET base material.The 3rd, the cross-linking reaction method arrives fluoride through crosslinking agent with the PET Thin Film, form a netted overall structure.These technologies in various degree exist complex process or the higher defective of energy consumption.Therefore be necessary to improve.
Summary of the invention
Deficiency to above-mentioned prior art exists the purpose of this invention is to provide the two-sided fluorine-containing notacoria production method of a kind of solar cell, and it has the simple and lower characteristics of energy consumption of technology.The present invention also provides dual coated device used in this production method.
To achieve these goals, the technical scheme that the present invention adopted is: the two-sided fluorine-containing notacoria production method of solar cell comprises modulation slurry and following steps:
A), handle basic unit: PET basic unit is carried out corona treatment;
B), apply fluorine-containing layer: the slurry that modulates is coated in the PET basic unit both side surface of carrying out corona treatment simultaneously, processes wet shape semi-finished product;
C), oven dry: the shape semi-finished product that will wet oven dry had both got the two-sided fluorine-containing notacoria of finished product.
Said step C) bake out temperature is 145～160 ℃, and stoving time is 1～8min.
Said step C) bake out temperature is 150 ℃, and stoving time is 2min.
In the used production method of the present invention; Through taking the both sides through the PET basic unit of corona treatment are applied simultaneously the mode of slurry, make the disposable while moulding of fluorine-containing layer of PET basic unit bilateral, need not to carry out loaded down with trivial details parameter control; Simple to operate, and need not to consume the more energy.
Used dual coated device comprises a pair of band lacquer roller that cooperatively interacts in the two-sided fluorine-containing notacoria production method of solar cell; The adjacent avris of band lacquer roller is provided with metering roll; Simultaneously; The dual coated device is provided with feeding device, and the discharging opening of this feeding device is compatible with the slit between band lacquer roller and the metering roll.
Be provided with the slit adjusting device between said band lacquer roller and the associated metering roll.
After adopting said apparatus, the advantage that the present invention had is: 1, the fluorine-containing layer thickness in both sides is even.PET basic unit is passed the slit between phase adjacent band lacquer roller, and the suffered pressure size in PET basic unit both sides is identical, thereby the fluorine-containing layer thickness of both sides is even and identical.2, fluorine-containing layer thickness is adjustable.After the optimization, the gap width between band lacquer roller and the associated metering roll is adjustable, thereby is with slurry thickness appended on the lacquer roller adjustable, and then makes the thickness of fluorine-containing layer adjustable.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is further specified:
Fig. 1 is the main TV structure sketch map of used dual coated device of the present invention.
Among the figure: 1, band lacquer roller; 2, metering roll; 3, feeding device; 4, slurry; 5, PET basic unit.
The specific embodiment
The following stated is merely preferred embodiment of the present invention, does not therefore limit protection scope of the present invention.
In following examples, the ingredient groups of slurry therewith is combined into (in the percentage composition of each ingredients constitute slurry gross weight):
Grind white slurry: 39.8% (wherein, each ingredients weight parts ratio is: main resin (Daikin GK570): titanium white powder: dispersant: 1-Methoxy-2-propyl acetate=42: 42: 4: 10); Main resin: 24.7% (Daikin GK570); Curing agent (functional resin): 17.2%; Amino: 2.2%; Promoter: 4.3%; Coupling agent: 6.5%; Drier: 0.2%; Activating agent: 1.2%; Levelling agent: 0.2%; Antifoaming agent: 0.2%; Flatting silica: 3.5%.Certainly, slurry is formed and can be different from the aforementioned component formation
See shown in Figure 1: used dual coated device comprises a pair of band lacquer roller 1 that cooperatively interacts among following each embodiment.What is called matches, and refers to this band lacquer roller 1 is parallel to each other, thereby form the slit between the two, and PET basic unit 5 is passed from this slit.Simultaneously, the adjacent avris of band lacquer roller 1 is provided with metering roll 2; The dual coated device is provided with feeding device 3.The discharging opening of this feeding device 3 is compatible with the slit between band lacquer roller 1 and the metering roll 2.That is: put into slurry 4 in the feeding device 3; Slurry 4 flows out to from feeding device 3 on band lacquer roller 1 and/or the metering roll 2; Also can be flowed directly in the slit between band lacquer roller 1 and the metering roll 2, thus the thickness of the slurry 4 that adheres on the width control band lacquer roller 1 in the slit between band lacquer roller 1 and the metering roll 2.Optimize, be with between the metering roll 2 that coats with lacquer roller 1 and match together and be provided with the slit adjusting device.Like this, through the width in the slit between adjustment band lacquer roller 1 and the metering roll 2, make on the band lacquer roller 1 and adhere to the slurry 4 of suitable thickness, and then make the fluorine-containing layer that applies suitable thickness in the PET basic unit 5.
Embodiment 1: after preparing slurry, may further comprise the steps:
