Abstract
A solar collector exhibiting durable fluorescent properties comprising a polymeric matrix, dye, and hindered amine light stabilizer, wherein the polymeric matrix is comprised of polycarbonate and the dye is comprised of a dye selected from the group consisting essentially of thioxanthone, perylene imide and/or thioindigoid compounds. The solar collector exhibits durable fluorescence which resists degradation by ultraviolet or visible radiation. The invention is optionally combined with reflective elements so that the sunlight collected may be directed to a solar cell.
