| 摘要 |
The present invention relates to an encapsulation sheet for a solar cell using a barrier layer and a preparing process thereof, the encapsulation sheet comprising a high molecule layer of polyolefin series between the layers made of ethylene vinyl acetate, thus having a laminated structure of ethylene vinyl, acetate layer, polyolefin layer, and ethylene vinyl acetate layer. The encapsulation sheet for a solar cell is the barrier layer not using a specific stabilizer, which prevents not only deterioration of encapsulation sheet itself even when constantly exposed to an environment of high temperature and humidity, but also decline of efficiency by blocking a leakage current, the reason for a sudden output reduction of a solar cell. |
