Backsheet Materials Increase Module Efficiency And Lifetime


Wilmington, Del.-based DuPont – a worldwide innovator of products and services for a variety of industries, including renewable energy – has developed the DuPont Tedlar PV2100 Series polyvinyl fluoride (PVF) film, which is used in the protective backsheet of PV modules.

According to the company, the backsheet is constructed as a tri-laminate of polyester film between two layers of Tedlar film, also known as TPT backsheets. The application of a film from the Tedlar PV2100 Series results in a backsheet with more stability.

‘The Tedlar PV2100 Series is another important example of how we are innovating to increase the life of solar modules, improve productivity and, ultimately, continue to make solar power a more viable alternative energy option,’ says Hilde Roekens, DuPont's global segment leader.

In addition, DuPont is manufacturing the PVF film at its Fayetteville, N.C., Louisville, Ky., and Buffalo, N.Y., facilities.
