Backsheet

Solar cell products are used in many industries because of energy saving, environmental protection, long service life and other advantages. The service life of such products is generally designed for more than 25 years, and the back film is the key to ensuring such a long life. The solar cell back film is located in the outer layer of the battery module, and is used to block the atmosphere after bonding with EAV to make the core area of the battery to achieve vacuum seal, and the primary task of sealing is to achieve water barrier, air barrier and electrical barrier, so the high-quality solar cell back film should have high electrical insulation, high weather resistance, high adhesion, low water gas transmission rate.

Note: Customized according to customer requirements.
