Description
PV backsheet is the encapsulation material on the rear side of monofacial PV modules; this dataset includes primary raw and auxiliary materials, energy consumption, atmospheric emissions, and waste generated during production processes. Infrastructure such as manufacturing of production equipment and construction of facilities are not included within the system boundary of the dataset; the life cycle inventory is compiled from data derived from multiple sources; the manufacturing process of co-extruded PV backsheets includes plastic pellet production (material mixing, extrusion granulation, cooling, and drying and pelletizing) and PV backsheet production (blending, extrusion, wiping, cutting, rewinding, and inspection processes).
Activity Description
The production process of co-extruded photovoltaic backsheets includes the plastic pelletizing process (mixing, extrusion pelletizing, cooling, and blow-drying cutting) and the photovoltaic backsheet production process (blending, extrusion, wiping, cutting, rewinding, and inspection).
Process Description
Photovoltaic (PV) backsheet is the encapsulation material on the rear side of a PV module and is located on the outermost layer of the module, typically used in single-glass encapsulated PV modules. The co-extrusion method for PV backsheets is a composite technology that involves extruding multi-layer polymer films. Fluorine-free backsheets are generally produced via co-extrusion, using polyethylene (PE) and polyolefin in the inner layer, and polyamide and polyolefin in the outer layer.
