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.
