Abstract
(EN)
Disclosed are a high-efficiency high-energy light photoelectric conversion material and a fabrication method therefor. The photoelectric conversion material comprises: a glass cover plate; a solar cell, the upper surface thereof and the bottom part of the glass cover plate being tightly glued by means of EVA; and a mounting groove that fixes the glass cover plate and the solar cell. The glass cover plate is double-layered glass, a lower layer thereof is high-light-density glass that is made using lead oxide, silicon dioxide, sodium carbonate, potassium nitrate and strontium oxide as raw materials and that has a refractive index nd value of 1.80-1.81; an upper layer of glass is low-light-density glass having a refractive index nd value of 1.50-1.53, wherein one side of the low-light-density glass that is not in contact with the high-light-density glass has an eccentric convex lens structure. An inner area of the mounting groove matching the solar cell is fixed with sound-insulating cotton, and an outer area of the mounting groove matching the glass cover plate and the solar cell is provided with a thermal-conductive silicone grease sealing structure. The present invention is suitable for areas with high-light-energy density, and has high-energy conversion efficiency, is heat resistance, cold resistance and weather resistance.
