The invention relates to the use of non-transparent methacrylate-containing single-, two- or multi-layer films in flexible photovoltaic systems, as well as the production of these films by extrusion coating, extrusion lamination (adhesive, melt or Hotmeltkaschierung) or adhesive lamination. This is z. As a thin, inorganic or metallic coated film, for. B. made of PET, with a weather-resistant film, z. B. from PMMA or PMMA polyolefin coextrudate, laminated or coextruded. In particular, laminates are produced in which at least one of the two layers is not transparent. An optional inorganic oxide or metal layer has the property of high barrier to water vapor and oxygen, while the PMMA layer brings the weathering stability. |
