3M PV Film Replaces Glass for Solar Panels

3M said the project will lower costs for U.S. commercial panel companies at a time when there is increased competition from foreign rivals. 3M said its new photovoltaic film is thin and lightweight, which cuts manufacturing time and replaces the need for the heavy glass used in rooftop solar modules. The film is also waterproof. The sun-facing
side is Fluoropolymer.

With our new production equipment and continued product innovation, 3M is well positioned to not only increase the performance of our Ultra Barrier Solar Film, but also significantly drive down the costs,” Derek DeScioli, 3M’s global business development manager for renewable energy, said Monday.

This revolutionary product is a result of more than a decade of development in transparent barrier technology, as well as over 45 U.S. patents and patent-pending applications. 3M™ Ultra Barrier Solar Film is engineered for flexible Copper Indium Gallium Selenide (CIGS), Cadmium Telluride (CdTe) and Organic Photovoltaic (OPV) solar modules. It’s designed to replace glass in flexible thin film solar panels, delivering high light transmission, superb moisture barrier performance and excellent weatherability. Compared with glass-glass modules, flexible PV modules manufactured with 3M™ Ultra Barrier Solar Film can reduce installation time, remove the need for metal racking, cut logistics expenditures and lower module manufacturing costs.
