Description
EVA encapsulant film is primarily used for encapsulation in crystalline silicon solar cells, with a small portion applied in thin-film solar cells, mainly serving to protect the cells and to tightly bond the solar cell pieces to the photovoltaic cover glass. The dataset includes key raw materials, auxiliary materials, energy inputs, atmospheric emissions, and waste outputs from the production process; however, infrastructure such as manufacturing equipment and factory construction is not within the system boundary of the dataset. The life cycle inventory is compiled from data derived from multiple sources. The manufacturing process of EVA encapsulant film includes feeding, batching, mixing, extrusion, embossing, thickness measurement, edge trimming, and inspection.

Process Description
Photovoltaic encapsulation film is a thin film material used for encapsulating photovoltaic modules, primarily applied in module-level encapsulation of solar panels. The main component of EVA (ethylene-vinyl acetate) encapsulation film is a copolymer of ethylene and vinyl acetate, along with various additives such as cross-linking agents, thickeners, antioxidants, and light stabilizers. EVA film is mainly used for encapsulating crystalline silicon solar cells, with a smaller portion applied in thin-film solar cells, primarily serving to protect the cells and firmly bond the solar cell chips to the photovoltaic cover glass.
