Abstract (en)

[origin: WO2014013186A1] The invention relates to optically active coatings for improving the yield of photosolar conversion, consisting of a transparent matrix containing a plurality of optically active constituents absorbing the light energy in a first absorption wavelength lambdaA1 and reemitting the energy in a second wavelength lambdaR1 different from lambdaA1, said optically active constituents being selected such that the reemission wavelength lamdaR1 of at least one type of constituent corresponds to the absorption wavelength lambdaA2 of at least one second type of constituent, characterised in that the C2/C1 ratio of concentration C1 of the optically active constituents of a first type in relation to the concentration C2 of the optically active constituents of said second type is between 0.13 and 0.26; Ci designating the concentration in moles per litre of the constituent i in relation to the doped matrix.
