The Dow Chemical Co. has unveiled Enlight polyolefin encapsulant films for photovoltaic modules. According to the company, the films can enhance efficiencies in photovoltaic module production, as well as provide greater module stability and improved electrical performance compared to traditional encapsulants, such as EVA-based products.
The films can be formulated to address specific module design needs, provide water vapor transmission rates that can range from 10-20 times lower than those of EVA materials, allow excellent adhesion to glass under various lamination conditions, show no creep in use, and offer a better matched refractive index to glass compared to EVA, Dow says.
The new encapsulant films are suitable for crystalline silicon and thin-film modules. They are listed with Underwriters Laboratories as ‘Recognized Components’ and will initially be produced at Dow's manufacturing plant in Findlay, Ohio.
