Definitions

  • the present invention relates to a manufacturing method of a coating composition for protecting solar cell module having excellent weatherability and durability. More precisely, the present invention relates to a manufacturing method of a coating composition for protecting solar cell module comprising the steps of synthesizing a compound by mixing a silicate composition prepared by hydrolyzing methyl silicate or ethyl silicate with excessive water and a titanium dioxide composition prepared by hydrothermal synthesis and aqueous synthesis; and coating solar cell module which is made of low iron transparent glass having excellent light transmittance and durability with the compound to increase maximum power generation of module and light transmittance, compared with the conventional low iron glass.
  • Solar cell materials are mainly produced by using single crystal silicon substrate or poly crystal silicon substrate, so the solar cell materials are weak in physical impact resistance. Besides, solar cell set up outside needs to be protected from rain, etc. And one sheet of solar cell generates small amount of electricity, so series and parallel connection of multiple solar cells are necessary to output practical electricity. Therefore, solar cell module has been produced to connect multiple solar cell materials and seal it with a transparent board and filler.
  • Solar cell module is a semiconductor device that converts light energy into electric energy by using photoelectric effect.
  • the light energy came into the spotlight because it is the pollution-free, noise-free unlimited clean energy.
  • Kyoto Protocol took effect from February 16, 2005, which limits the output of greenhouse gas such as carbon dioxide and methane to counter the global warming.
  • At least 80% of energy source in Korea depends on imports, so it is needless to say that solar energy is the most important alternative energy in Korea.
  • Solar cell module generates electricity by using multiple solar cells connected by serial-parallel connection by conductive ribbons and provides electricity to a user. Then, the user can use this electricity as a commercial power source.
  • solar cell modules are set up outside, for example on the roof of a building, on the side wall of a building, in the mountains, on the island, in the park, on the signals, on the road signs, etc., to provide electricity thereto.
  • the back protective sheet layered on solar cell module prefferably has excellent mechanical strength and durability including weatherability and hydrolysis resistance to protect the back side of the solar cell module.
  • Module is produced by lamination method, in which transparent front substrate, filler, solar cell device, filler and back protective sheet are layered sequentially, followed by vacuum suction and hot pressing.
  • Solar cell is, in fact, for outdoors, so that materials consisting the solar cell module must have excellent durability.
  • a protective sheet is generally used, so that this sheet is also required to have excellent mechanical strength and durability such as weatherability and hydrolysis resistance .

  • the composite film comprising the fluorine-based resin film and the metal thin film has a problem of short-circuit generated by crack or something resulted from external force. So, it needs to be improved to be used as a material for the back protective sheet for solar cell module. It also needs to be improved in its anti—short property which is one of the major characteristics ' required for packing materials of electric device such as solar cell module using metal thin film on which comparatively high voltage is applied.
  • the fluorine-based resin film is suitable for weight- reduction which favors handling.
  • the fluorine film itself has excellent weatherability but it allows UV to pass through, so that solar cell module components can be easily deteriorated by UV, adhesion is reduced and the strength of the structural material is decreased.
  • the fluorine film containing UV absorber when a gas barrier film of PET film bass is used in surface protective sheet construct, the module was easily affected by UV and electricity power generation efficiency was reduced. Besides, the waste treatment might be a burden of environmental problem. So this film seemed not the most appropriate component for solar cell module, particularly for such clean energy.
