Abstract
The invention provides preparation of a fluorescent synergistic film for a solar cell. According to the technical scheme, the preparation comprises the following steps: by taking SiO2, Al2O3, PbF2, CdF2 and rare earth ion oxides as matrix materials, and preparing a glass precursor by virtue of a high-temperature solid-phase melting method; preparing a highly rare-earth-doped fluoride nanocrystalline by adopting a thermal induction corrosion method, namely performing controllable growth on fluoride nanocrystalline luminous particles in the glass precursor; and corroding the oxide matrix around the rare-earth-doped nanocrystalline by utilizing hydrofluoric acid, and releasing the fluoride nanocrystalline. The preparation method disclosed by the invention has the advantages that the preparation method is simple and easy to implement; according to a fluorescent synergistic layer prepared by utilizing the material, all the light can be basically absorbed in a long-wavelength region of a CIGS solar cell, sunlight in a short-wavelength region which cannot be utilized by the CIGS solar cell can be effectively converted into long-wavelength region fluorescence, and the photoelectric quantum conversion efficiency of the CIGS solar cell is improved.
