A luminescent solar collector is provided comprising a substrate and a light energy converter, such as a photocell, operatively connected thereto. The substrate is molded from a thermoplastic composition comprising a polymer and a fluorescent dye or quantum dot dispersed therein. The polymer comprises a polycarbonate unit and a polyester unit derived from the reaction of isophthalic acid, terephthalic acid, and resorcinol (ITR). In further embodiments, the substrate comprises two or more layers including a fluorescent layer and an overcoat layer. The fluorescent layer comprises the fluorescent dye or quantum dot and a polycarbonate polymer. The overcoat layer comprises the ITR unit. The substrate, in single layer or multiple layer form, has reduced haze levels over a prolonged period of time. |
