Introduction
Solar cell background film acts as protecting solar cell, most of which is TPT compound film by Tedlar, Polyester and Tedlar with white color. The sunlight and infrared is reflected on it to avoid high temperature of solar module reducing solar energy efficiency. The parameters of our products are as same quality as foreign relative products, which had been proved by state-authority organ.
Characteristics
The film is of anti-aging£¬Solvent resistance£¬proof£dust and Gas-tight with excellent Mechanical properties of polyester. Barrier and low water absorption prevent EVA and solar cell from water, oxygen and Corrosive liquid gas (such as acid rain). Solar module is of aseismetic capability as EVA¡¯s Flexibility and TPT¡¯s Tenacity improve comprehensive protection role to solar module.
