Do obeisance to ear to roll out a solar battery to use polyurethane film
From;  Author:Stand originally
At present installed capacity of establishment of global solar energy grows with exponential type almost, development generates electricity the solar battery component with efficiency and manufacturing higher efficiency becomes very important. Company of science and technology of the material that do obeisance to ear achieves major breakthrough in this respect of late. Development of personnel of this company research and development is able to bear or endure one kind successful light is thermoplastic polyurethane, the production that is a solar battery offerred new solution. Through with Germany a company cooperates, company of science and technology of the material that do obeisance to ear uses this kind of polyurethane to make the new-style film that is VISTASOLAR into a kind of trade name, use its as solar battery raw material replaces traditional EVA (copolymer of ethylene of ethylene acetic acid) filmy, make the production of the solar battery more convenient not only and quick, also raised a solar battery greatly generate electricity efficiency.
When producing a solar battery, it is commonly mix glass of silicon chip park between the base material that includes Fu with EVA film, put them in vacuum layer to close together next machine is immanent 12 ~ of the cross-linking below 145 ℃ 20 minutes, EVA hardens to become hyaline layer thereby. But this kind of method is put in a few inadequacy, if needed to proper time is finished and limit the manufacturing efficiency of the solar battery as a result of cross-linking, the maintenance of the solar battery is additionally no-go also. And be able to bear or endure smooth polyurethane film has very good transparency, pervious to light the gender is good, melting point is high, cross-linking need not undertake when the solar battery that make, can accelerate the manufacturing process of the solar battery, reduce manufacturing cycle, return what can raise a solar battery to generate electricity at the same time efficiency and utilization rate.
This kind is able to bear or endure smooth polyurethane film still has a lot of other advantages. For example can more change conveniently imperfect or broken component, and encountering such problem before is repair or reproduction without giving thought to need a flower for a long time, because,this is thermoplastic polyurethane but new melt, make its in-house and costly solar battery can be used again. Additional, memory is more simple also, because this is planted film comparing and add the EVA film that cross-linking agent undertakes cross-linking passes stronger.
