6 FAQs about [Fluorine film for solar cell backsheet]
What is a fluorine solar module & how does it work?
The inner fluorine material shields the PET from UV corrosion, and with special treatment and encapsulation of the adhesive film, it enhances bonding. The outer fluorine material provides protection for the back of the solar module against moisture, heat, and UV erosion.
What is a fluorine-free backsheet?
To reduce costs and consider environmental factors, fluorine-free backsheet structures, such as the APE structure, were introduced. A typical backsheet is composed of three core layers: Outer Protective Layer (Weathering Layer): For optimal weather resistance, the outer layer material usually contains fluorine.
What is a double sided fluoropolymer backsheet?
The TPT backsheet, using a composite process, is the most common type of double-sided fluoropolymer backsheet available in the market. It combines DuPont’s Tedlar brand PVF fluorine film from the United States with an intermediate layer of PET base film, bonded together with adhesive.
What are thin-film solar modules?
UV-stable and hydrolysis-stable polyester film for reliable external protection Thin-film solar modules need to be protected against the ingress of moisture. This is ensured by an additional barrier layer in the form of an aluminium inner layer. Thin-film modules have a cost-optimised design based on glass-film technology.
What is a PV module backsheet?
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.
Why do photovoltaic cells need a backsheet?
Water and dust particles can lead to corrosion and pitting, posing a threat to photovoltaic cells. The backsheet’s role is to shield against moisture-related damage, including corrosion of electrical connections, insulation degradation, and the risk of short circuits.
