| EVA Adhesive Film for Encapsulation Solar Cells |
The film is applied to encapsulate solar cells. It is not adhesive at room temperature to ease operation. A novel heat cured hot-melt film, it makes permanent and adhensive tight seal through
cross linking and enhanced bonding when the fim is heated and pressed. The solar cell encaps
ulated
by this film has been tested and applied outdoors for 20 yeas. Many applications were
gained in National Light Engineering in 2002. |
