TECHNOLOGY FOCUS - POLYMERS - Preferred Module: The photovoltaic module further comprises a first cap layer disposed on a surface of the core layer, where the first cap layer comprises polycarbonate and a UV light absorbing stabilizer; and a second cap layer, where the core layer is disposed between the first cap layer and the second cap layer, where the second cap layer comprises a member selected from polycarbonate, ethylene vinyl acetate copolymer with a vinyl acetate content of 2-10 wt.%, polyethylene, polypropylene, and cyclic olefin copolymer. Preferred Sheet: The multilayer sheet further comprises a second cap layer, where the core layer is disposed between the first cap layer and the second cap layer, where the second cap layer comprises a material selected from bisphenol-A polycarbonate, polycarbonate copolymers, polyethylene, and/or polypropylene. Preferred Method: The method further involves co-extruding a second cap layer comprising polycarbonate, where the core layer is disposed between the first cap layer and the second cap layer; and laminating a second cap layer comprising a polyolefin to the core layer, where an adhesive layer is disposed between the core layer and the second cap layer, and where the core layer is disposed between the first cap layer and the adhesive layer. Preferred Components: The first cap layer comprises a resorcinol polyarylate carbonate copolymer. The second cap layer comprises a cyclic olefin polymer, where an adhesive layer is disposed between the second cap layer and the core layer. The second polycarbonate is present in an amount of 20-50 wt.%, preferably 40-50 wt.%, and the third polycarbonate is present in an amount of 10-50 wt.%, preferably 10-25 wt.%, based on a total weight of the composition of 100 wt.%. The thermal shrinkage is less than 1% along the machine direction and the transverse direction after a thermal treatment at 150 degrees C for 30 minutes. The first cap layer comprises a member selected from polycarbonate and UV light absorbing stabilizer, and/or resorcinol polyarylate carbonate copolymer. The first cap layer comprises a fluoropolymer selected from polyvinylfluoride, polyvinylidene fluoride, polytetrafluoroethylene, ethylene-tetrafluoroethylene copolymer, polychlorotrifluoroethyelene, ethylene-chlorotrifluoroethylene copolymer, and/or tetrafluoroethylene hexafluoropropylene vinylidenefluoride. The third polycarbonate is present in an amount of 0-40 wt.%, based on a total weight of the composition of 100 wt.%. EXAMPLE - No suitable example given.
