Abstract

The invention discloses a solar cell glass antireflection light-conversion synergistic paint which is composed of an antireflection component, a latent light-conversion component, a paint stabilizing and membrane enhancing agent, a coating regulator and a solvent water. The paint is characterized by using nano SiO2 particles, nano MgF2 particles and nano rare earth ytterbium / erbium / terbium oxide particles as the antireflection material, the antireflection material is also a latent light-conversion material, and the latent light-conversion material forms the silicon-dioxide-coated rare-earth-doped fluoride / silicate-doped up / down light-conversion material in the coated glass high-temperature tempering process. The paint can adapt to the existing solar cell glass engineering coating technique and solar cell glass tempering technique, and solves the problems of complex preparation technique and poor compatibility with the antireflection component in the light-conversion material. The paint can fully utilize the near-ultraviolet light and near-infrared light in the solar spectrum, lowers the heating effect of the battery, and can obviously enhance the photoelectric conversion efficiency of the solar cell.
