Daokangning: Cut material of EVA of solar battery cost

PUWORLD (08/10/07) -- American path Kang Ning (Dow Corning) the data of new fund silicon that development gave to be able to cut down solar battery module to make cost. Exhibit in EU PVSEC on the meeting, revealed use the new material, module in company in-house trial-produce.



The EVA that what Daokangning develops this is unit of agglutinate solar battery and glass (ethylene - copolymer of acetic acid ethylene) replace data filmily. When using EVA film, heat through cascade, make unit of filmy agglutinate solar battery reachs glass. Handle time side, processing needs the left and right sides 15 minutes when 4 module. Average the processing time of every module is controlled for 4 minutes.

And new material side, "Detail inconvenience discloses, it is to pass material of silicon of shape of besmear cloth liquid to wait nevertheless, make solar battery unit and vitreous agglutinate " (explanation member) . The processing time of every module is 60 ～ 90 seconds. Come so, compare with the photograph when use EVA is filmy, can cut the integral cost that includes material to reach production device to wait inside.

Additional, the solar battery unit that trial-produce module uses joins light energy to offer by Chinese day
