Back-sheet materials for photovoltaic modules serve several purposes such as providing electrical insulation, environmental protection and structural support. These functions are essential for modules to be safe for people working near them and for the structures to which they are attached.
On the back side of a PV module backsheet films are used. Backsheets are multilayer laminates made from various polymeric materials and inorganic modifiers. The multilayer structure allows tailoring the optical, thermo mechanical, electrical and barrier properties of backsheets according to specific requirements for PV modules.
Tedlar® PVF film-based backsheet is the industry standard for solar backsheets Tedlar® PVF film-based backsheet designs have been in the field for more than 30 years in different climates, including deserts, tropical locations, seashores, and mountainous terrains.
