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.

A system and method for the treatment of a skin comprising. The system comprises an applicator having a cavity and one or more light sources configured to irradiate the cavity with optical energy simultaneously from at least two directions. The applicator is applied to the skin and a region of skin is made to protrude into the cavity. The protruding region of skin is then irradiated with optical energy from the one or more light sources simultaneously from at least two directions.
