  • Patent number: 9112075
    Abstract: Provided is a copper indium gallium selenium (CIGS)- or copper zinc tin sulfur (CZTS)-based solar cell including a back electrode layer and a light-absorbing layer, wherein the light-absorbing layer has a composition of CuxInyGa1-y(SzSe1-z)2 (wherein 0.85?x<1, 0<y<1, 0<z<1, and each of x, y and z represents a real number) or Cu(2-p)Zn(2-q)Snq(SrSe(1-r))4 (wherein 1.4?p<2, 0<q<2, 0<r<2, and each of p, q and r represents a real number). The CIGS- or CZTS-based thin-film solar cell causes no interlayer delamination and has improved durability and photoelectric conversion efficiency. Also provided is a method for fabricating a CIGS- or CZTS-based thin-film solar cell by which conversion of molybdenum back electrode layer to molybdenum diselenide is controlled.

  • Patent number: 8759142
    Abstract: Disclosed is a method for producing a copper indium selenium (CIS) or copper indium gallium selenium (CIGS) thin-film light-absorbing layer. The method includes forming a coating layer of CIGS slurry, removing a solvent, a dispersant and a binder from the coating layer to form a powder coat layer, pressing the powder coat layer to improve its particle packing density, and heating the powder layer to form a dense thin film. The method uses a powder process as a non-vacuum process to produce a CIS or CIGS thin film in high yield at low cost. Further disclosed is a method for manufacturing a thin-film solar cell including the production method.

  • Publication number: 20130247978
    Abstract: It is disclosed that a photo-electrode of a dye-sensitized solar cell comprising faceted anatase-type titania nanoparticles which adequate for fabricating a photo-electrode of a dye-sensitized solar cell which is efficient and longlasting and a fabrication method thereof. The titania nanoparticles can provide high photoelectric conversion efficiency of the solar cell with help of fast electron mobility due to its high crystallinity and can reduce process time required for adsorbing the dye molecules on the surface of the titania nanoparticles. By modifying surface characteristics of the titania nanoparticles, it is allowed for dye molecules to be easily adsorbed on the surface of the titania nanoparticles and the life span of the dye molecules adsorbed on it is expanded with help of reduced photo-degradation rate of them at service conditions.
