Background technology
Energy and environment are two large basic problems of 21st century facing mankind.Developing pollution-free, reproducible new forms of energy is the only ways that solve this two large problems.At present, photovoltaic generation proportion in the energy is minimum, and high cost is the major obstacle of restriction photovoltaic generation large-scale application.Development of New Generation high-level efficiency, solar module cheaply, approach even lower than conventional energy resources its cost of electricity-generating, and this has become the problem of the most important thing.
At present in solar cell package, battery plus-negative plate need to be used isolating bar to carry out the insulation isolation of positive and negative electrode at bus-bar place, module edge, this isolating bar need to have good electrical isolation and stability, need the bonding that can maintain a long-term stability with EVA, cell piece, welding simultaneously, conventionally use at present EVA and back veneer material to isolate component bus bar, while placing isolating bar, operation steps is complicated, causes production efficiency reduction, manufacturing cost to increase.Simultaneously, solar-energy photo-voltaic cell module need to be at outdoor absorption solar irradiation, and under long-time ultraviolet irradiation, the photoelectric transformation efficiency of solar-energy photo-voltaic cell module can decline very soon, thereby lose practical value, therefore need isolating bar to have stronger resistant function to uviolizing.
Summary of the invention
The present invention wants technical solution problem to be: the shortcoming that overcomes above-mentioned technology, a kind of production method of electrode isolation bar and the isolating bar of use the method generation of solar cell module are provided, this isolating bar not only has good cohesiveness, and has stronger anti-uv-ray.
In order to solve the problems of the technologies described above, one of technical scheme that the present invention proposes is: a kind of method of manufacturing solar cell module isolating bar, and described isolating bar is made by the PET base material of sheet, said method comprising the steps of:
1) PET base material is carried out to corona treatment;
2) following raw material is by weight mixed: 100 parts of EVA particles, 0.2～0.5 portion of ultra-violet stabilizer and 0.5～0.8 part of coupling agent, obtain mixed EVA glue;
3) mixed EVA glue is coated in to the two surfaces of PET base material that corona treatment is crossed, the PET base material after being applied;
4) the PET base material after applying is carried out to surface with ozone and process again, obtain the isolating bar of solar cell module.
As preferred version, in step 1), adopting voltage is that the alternating-current that 8～12KV, frequency are 20～50KHz carries out corona treatment to PET base material.
As preferred version, in step 4), be that the PET base material after applying is inserted to ozone concn is that 20～40 mg/litre, temperature are that the surface treatment stove of 50～70 ℃ carries out surface and processes, the treatment time is 20～60 minutes.
As preferred version, described ultra-violet stabilizer is hindered amine light stabilizer, and described coupling agent is titanate coupling agent.

PET (being polyethylene terephthalate) material has good insulativity and stability, EVA glue is had to stronger cohesive force, after pet layer is applied to EVA glue, both have good consistence, when raising, temperature can combine together, the bonding that can maintain a long-term stability with cell piece, welding etc.
The surface tension size of PET base material has a great impact the cohesiveness of itself and EVA coating, surface tension is generally used dyne value representation, dyne value is higher, illustrates that the surface energy of PET base material is more, so the surface of explanation PET base material and the cohesiveness of EVA coating stronger.The present invention carries out corona treatment to PET base material, exactly with utilizing high frequency high-voltage at processed PET substrate surface discharge generation low-temperature plasma, make the surface of PET base material produce free radical reaction and make polymkeric substance occur to be cross-linked, thereby make the surperficial roughen of PET base material and increase its wettability to EVA coating, these gas ions electric shock and penetrate into its molecular structure of surface breakdown of PET base material, and then by surface molecular oxidation and the polarization of PET base material, making PET substrate surface produce small groove fills rough and uneven in surface, increased the roughness of PET substrate surface, therefore increased the sticking power of PET substrate surface.Therefore, through the PET base material of corona treatment, it is large that surfaceness becomes, and it is large that capillary dyne value becomes, thereby the cohesiveness of itself and EVA coating is increased greatly.
The PET base material of the present invention after to described coating carries out high-pressure ozone processing, because the oxidisability of ozone is extremely strong, can make the surface of PET base material produce hydroxyl, carbonyl isoreactivity functional group, can make the surface oxidation of PET base material form some superoxide, make PET and coat strengthen solidifying simultaneously, and by the energy of ozone, make EVA and PET intermolecular have stacked, and then the cohesive force between increase EVA and PET.
The present invention adds coupling agent in EVA particle, can well improve the interface interaction between organism and inorganics, and this interfacial layer can transmit stress, improves the proof stress of EVA particle, further strengthens the cohesive strength between EVA particle and PET base material.In addition, in EVA particle, add ultra-violet stabilizer, can make isolating bar of the present invention have stronger resistant function to uviolizing, even if like this solar-energy photo-voltaic cell module is exposed to the open air for a long time under ultraviolet ray, its photoelectric transformation efficiency also can not decline very soon and lose practical value, thereby has expanded the scope of application of positive energy photovoltaic cell module.
