NOVELTY - A luminescent solar collector (10) comprises a sheet (20) connected to a light energy converter such as a photocell (90). The sheet contains a polymer, and a fluorescent dye or quantum dot dispersed in the polymer; where the polymer includes a polycarbonate unit, and a polyester unit derived from reaction of isophthalic acid, terephthalic acid and resorcinol. The fluorescent dye or quantum dot absorbs light, and radiates the absorbed light at a longer wavelength. The sheet transmits the radiated light to the light energy converter.    USE - As a luminescent solar collector useful for capturing solar energy to generate electricity.    ADVANTAGE - The sheet has reduced haze levels over a prolonged period. Thus, the luminescent solar collector resists haze formation for an extended period. The luminescent solar collector can withstand elements for 10-15 years, without significant increase in haze. Consequently, the edge emission of the luminescent solar collector remains high for 10-15 years. The reduction in energy efficiency of luminescent solar collector caused due to the haze, is prevented. The fluorescent dye or quantum dot in the sheet, has a maximum absorbance wavelength of greater than 430 (preferably 800-950) nanometers, and a quantum yield of greater than 75%.    DETAILED DESCRIPTION - A luminescent solar collector (10) comprises a sheet (20) connected to a light energy converter such as a photocell (90). The sheet contains a polymer, and a fluorescent dye or quantum dot dispersed in the polymer; where the polymer includes a polycarbonate unit, and a polyester unit derived from reaction of isophthalic acid, terephthalic acid and resorcinol. The fluorescent dye or quantum dot absorbs light, and radiates the absorbed light at a longer wavelength. The sheet transmits the radiated light to the light energy converter. The polymer further comprises an ultraviolet (UV) agent. Alternatively, the sheet comprises a fluorescent layer, and an overcoat layer covering the fluorescent layer; where the fluorescent layer contains a polycarbonate polymer dispersed with a fluorescent dye or a quantum dot, and the overcoat layer contains a block copolymer having a polyester unit derived from reaction of isophthalic acid, terephthalic acid and resorcinol. The light energy converter is connected to at least the fluorescent layer, and the fluorescent layer transmits the radiated light to the light energy converter.
