EVA film for solar cell encapsulation:
EVA film is based on the basic material EVA resin (ethylene and vinyl acetate copolymer resin), by adding a
variety of modified additives, through melt extrusion, then become the thermosetting film. It is not sticky in
normal temperature and easy to operate. By heating laminating, it produces crosslinking curing reaction and
bonding enhanced reaction which tightly bonding the silicon chip, glass, TPT multilayer material material
together then becomes the solar cell panel. In actual outdoor application, its service life can reach 30 years.
A large number of applications of the solar panels well-proved that EVA film is the optimum cost and
irreplaceable solar cell packaging material.
The main characteristics of EVA film follows:
1. Special productive technology, high efficiency and fast reaction reduce the thermal contraction of film.
2. Good and stable adhesion avoid EVA film turning to be yellow under the bad environment like strong lights,
hot humid.
3. High light transmission rate improves the visible light transmission and ensures the power conversion rate of
solar cell.
4. Role with the absorption of UV low permeability in ultraviolet region, improve the product from ultraviolet
aging resistance.
5. The outstanding weather resistance (bears UV, bears damp hot also low temperature), satisfies the outdoor
long-term operation requirements.
6. High insulation resistance, each square meter volume resistance can reach to 600 megohms.
7. The high melt strength and the outstanding viscoelasticity can reduce the harm effectively that the lamination
pressure to the battery piece.
8. Excellent shrinkage ratio could effectively decrease the constriction caused by heat.
9. Special surface treatment benefits to vacuum out the air, avoid the hidden trouble of air bubble and ensure
the cell isolated from air.
10. Special production technology ensures the steady of products and adaptiong to various operation of
laminating machine.
