introduction to types of eva solar photovoltaic films

eva solar photovoltaic film is a material that plays a key role in the packaging of photovoltaic modules and is one of the materials of photovoltaic modules.

1. transparent eva film: used for photovoltaic module packaging, with high resistance to pid, high light transmittance, resistance to uv yellowing, resistance to snail marks, and good adhesion to glass and backplanes. the disadvantages are poor reflectivity and water permeability. high efficiency, easy to produce pid phenomenon; widely used in the packaging of the upper layer of single/double glass components;

2. white eva film: used for encapsulation on the underside of photovoltaic module cells. it has high reflectivity. the white eva film can make sunlight re-reflected to the cell surface, improving the power generation efficiency of solar modules; it can meet the needs of single-glass modules, double-glass modules and thin-film modules require high-yield packaging and processing, and the price is relatively high.
