Abstract: In an embodiment, a photovoltaic module, comprises a transparent superstrate; a backsheet, wherein the backsheet comprises a core layer comprising a core composition formed from a first polycarbonate comprising dimethyl bisphenol cyclohexane carbonate repeat units and bishpenol-A, wherein the first polycarbonate has the structure wherein the dimethyl bisphenol cyclohexane carbonate repeat units are present in an amount of 10 wt. % to 50 wt. %, based on the total repeat units in the core composition; and a second polycarbonate selected from the group consisting of a bisphenol-A polycarbonate homopolymer, a polyphthalate carbonate copolymer, a polycarbonate copolymer comprising 2-phenyl-3,3-bis(4-hydroxyphenyl) phthalimidine carbonate and bisphenol-A carbonate repeat units, a polycarbonate copolymer comprising bisphenol-A carbonate and tetrabromobisphenol A carbonate repeat units, and combinations comprising at least one of the foregoing; and a photovoltaic cell between the superstrate and the backsheet.

Abstract: A separator spline formed of a foamed, halogen-free polymeric material for separating twisted pairs of conductors is described. The isolator may take the shape of an “X”, a +, a rod, a star configuration, a tube or a flat rectangular shape, with the isolator separating twisted pairs of conductors. In the case of the “X”-shape, the twisted pairs are separated by the arms of the X. The halogen-free polymeric material is preferably selected from a resin selected from the group of polyetherimide (PEI), polyetherimide/polysiloxane copolymer, elastomer-modified-polyphenylene-ether blend, and combinations thereof. The isolator and twisted pairs are preferably part of a communication cable and being covered with a sheath.
