The present invention outlines a method for fabricating poly(ethylene-co-vinyl acetate) (PEVA-SUN), intended for use as an encapsulant sheet in the photovoltaic (PV) industry. This invention challenges the conventional approach in the PV industry, which typically uses EVA sheets with a VA content between 28 to 33%. Instead, this method recommends utilizing a VA content of 19-21% for the front side encapsulation and 21-23% for the back side encapsulation in the PEVA copolymer.

The invention enhances the quality of solar panels while also decreasing the cost required. This makes solar energy more accessible and affordable for the public and will help in increasing green energy consumption.
- Reduces the vinyl acetate (VA) content to 19-21% and 21-23% by weight in the PEVA copolymer for the front and back side encapsulation
- Front layer encapsulation film has lower vinyl-acetate content than the back layer encapsulation film
- Increases the stability of the encapsulation sheet against the environmental stressors
- Reduces the manufacturing cost
