The silicon wafer is very fragile, and if you touch the outermost glass directly, it's very easy to damage. So there's a EVA solar cell glue film

General EVA manufacturers can do the thickness of 0.3-0.8mm, compared to the conventional size is about 0.5mm, but it is some EVA flat film, some have double embossing, double sided embossing is measured when the thickness difference is about 0.5mm, 0.5MM film, measuring the time of 0.55MM, I am EVA production technical personnel. EVA film provides good protection and does not affect efficiency, and has many advantages. Advantages of adhesion, durability, optical properties and so on.

1, curing conditions: fast curing adhesive film, heating to 135~140 degrees, constant temperature 15~20min; conventional plastic film, heated to 145 degrees, constant temperature 30min.

2, transmittance: greater than 90%.

3. Crosslinking degree: the cured film is more than 70%, and the conventional film is more than 75%.

4, peel strength: glass / film is greater than 30N/cm, TPT/ film is greater than 20N/cm.

5, temperature resistance: high temperature 85 degrees, low temperature -40 degrees, not thermal expansion, cold shrinkage, good dimensional stability.

6, ultraviolet resistance aging performance: long time ultraviolet irradiation is not crack, not aging.
