Encapsulant films for PV modules
The Dow Chemical Company (Dow) is introducing ENLIGHT Polyolefin Encapsulant Films, which can enhance efficiencies in PV module production and lead to lower conversion costs. The films also can provide greater module stability and improved electrical performance versus traditional encapsulants (such as EVA-based products), which improves the reliability and extends the service life of PV modules. The new encapsulant films are suitable for C-Si and thin-film modules.
Based on fully integrated polyolefin technology, these encapsulant films: provide Water Vapor Transmission Rates (WVTR) that can range from 10 to 20 times higher than EVA materials; allow excellent adhesion to glass under various lamination conditions; show no creep in use; offer a better matched refractive index to glass compared to EVA; and are listed with Underwriters Laboratories (UL) as “Recognized Components.”
