Process Description
Photovoltaic encapsulation film is a thin film material used for encapsulating photovoltaic modules, primarily applied in module-level packaging of solar panels. PVB film is a polymer formed by the condensation reaction between polyvinyl alcohol and butyraldehyde, mainly used in thin-film solar cells, double-glass modules, building-integrated photovoltaics (BIPV), and other fields.
