Abstract
A method for making a light-collector of a transparent plastic and a fluorescent dye, wherein the monomers forming transparent plastics are mass-prepolymerized in the presence of radical catalysts and the fluorescent dye is added before, during or at the end of prepolymerization, and then polymerizing the mixture to completion by adding another catalyst, also at pressures of from 2 to 20 bars and at temperatures of from 50.degree. to 160.degree. C., and the use of the light-collector thus produced in combination with photovoltaic elements, preferably based on Ga/As or Si.
