Glass-Glass Module Design Removes the Backsheet Application
Replacing a polymer backsheet with a second sheet of glass improves module durability, enables bifacial energy capture, and increasingly costs less as thin glass supply has expanded. That design already covers 58% of new manufacturing capacity and continues gaining. Backsheets take 39% of fluoropolymer film volume, so this is not a share shift between suppliers but the closure of an application. Producers who added capacity through the solar boom face utilisation problems that no commercial effort resolves at all. Utilisation on lines built for backsheet volume is the immediate consequence and it arrives faster than most planning assumed.
