In solar panels, what is EVA film used for?
The most widely used encapsulating material in the solar photovoltaic (PV) module manufacturing sector is EVA film. Solar cells are laminated between EVA sheets using a laminator while compressed and vacuumed.
At temperatures as high as 150°C, this activity takes place. EVA film is a hot-melt adhesive film used in solar cells. It is not sticky at room temperature, but when heated to a high temperature and heat-pressed, it solidifies and becomes adhesive, becoming fully transparent.
After curing, the film has excellent light transmission, robust adhesion, thermal stability, airtightness, and age resistance. Extensive experience has demonstrated that EVA film performs satisfactorily when used outdoors and for encapsulating solar cells.
How Thick is the EVA in Solar Panels?
Typically, EVA film used in solar panels has a thickness of 0.4 to 0.6 mm. This thickness was selected with care to provide a level and consistent surface, which is essential for the efficient encapsulation and safeguarding of the solar cells.
The crosslinking ingredients in the EVA film allow it to crosslink at a curing temperature of about 150°C. Extrusion molding is used to accomplish this procedure, creating a solid adhesive coating that firmly attaches the solar cells to the protective layers.
Anti-ultraviolet, antioxidant, and curing chemicals are frequently included into an EVA film layer with a thickness range of 0.4-0.6 mm. The process of sealing and bonding between EVA, glass, and backsheet depends on these elements.
Why is EVA Film Optimal for Photovoltaic Arrays?
EVA film excels in solar panel construction due to its beneficial traits:
1. Light Permeability: Allows maximum sunlight to reach cells.
2. Adhesive Prowess: Unites panel components securely.
3. Resilience: Withstands environmental challenges.
4. Pliability: Absorbs stress, safeguarding cells.
5. Chemical Fortitude: Resists corrosive substances.
These characteristics boost efficiency, longevity, and robustness of solar modules.
