Ultra barrier solar film

3M

3M is introducing its 3M Ultra Barrier Solar Film for flexible Copper Indium Gallium Selenide (CIGS), Cadmium Telluride (CdTe), and Organic Photovoltaic (OPV) solar modules. 3M Ultra Barrier Solar Film is highly transparent, provides moisture vapor transmission rates (MVTR) below 5 * 10-4 g/m2/day, and demonstrates excellent durability. The product is the result of more than a decade of development in transparent barrier technology as well as over 45 U.S. patents and patent-pending applications covering construction, materials and processes. The company also plans to begin high-volume production of the Ultra Barrier Film to supply 3M's global thin film solar customer base, including manufacturers throughout the United States, Europe and Asia.

Designed to address the needs of flexible thin film solar manufacturers, 3M Ultra Barrier Solar Film acts as a replacement for glass with high light transmission, superb moisture barrier performance, and excellent weatherability. Compared with glass-glass modules, large area, light weight flexible PV modules manufactured with 3M Ultra Barrier Solar Film can achieve lower balance of systems (BOS) costs by requiring less installation time, removing the need for metal racking, and reducing logistics expenditures. 3M Ultra Barrier Film also enables lower module manufacturing costs by allowing manufacturers to commercialize large area modules, effectively reducing fixed costs associated with module manufacturing, assembled in a continuous roll-to-roll process.
