3M™ Ultra Barrier Solar Film

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.
