Technical FAQs 4
Why is Eva used in 80% of solar cells?
EVA is used in about 80% of solar cells because it is inexpensive, flexible, chemically stable, and has a high degree of transparency . The EVA is a copolymer made up of the monomer ethylene and vinyl acetate. Vinyl acetate is an amorphous nature, whereas polyethylene is semicrystalline .
Does Eva film Bond to solar glass?
Under the right circumstances, EVA film will have excellent adhesive bonding to solar glass (NOT standard glass, solar glass has a rough surface). Also EVA bonds very well to the backsheet. EVA is known for its excellent transparency.
How to encapsulate solar cells?
In the solar industry, the most common encapsulation is with cross-linkable ethylene vinyl acetate (EVA). With the help of a lamination machine, the cells are laminated between films of EVA in a vacuum, which is under compression. This procedure is conducted under temperatures of up to 150 °C.
Is Eva a transparent solar module?
EVA is known for its excellent transparency. This means that the optical transmission is acceptable and doesn't block too much of the sunshine trying to reach the solar cells. Nowadays, several manufacturers in Asia use a transparent backing, which has transparency between the cells as a result. This type of module is known as semi-transparent.
