Abstract: Disclosed herein is a wallpaper, including: (a) a paper substrate including a paper layer and an ink decorative layer attached to an upper surface of the paper layer that faces away from the wall during use; (b) a fluorine-containing coating attached to a surface of the ink decorative layer; and (c) a supporting layer attached to a lower surface of the paper substrate, in which the supporting layer comprises 25 to 45 wt % of polyacrylate, 25 to 40 wt % of a styrene-acrylic acid copolymer and 10 to 50 wt % of inorganic particles based on the total weight of the supporting layer, wherein the inorganic particles are selected from the group consisting of silicon dioxide, titanium dioxide, calcium carbonate, kaolin clay, diatomite and talc powder, and a combination of two or more thereof.
Abstract: Disclosed herein are solar cells comprising semiconductor substrates and Cu electrodes attached thereto, wherein, the Cu electrodes are derived from conductive pastes containing powder mixtures of Cu particles and crystalline Ge particles and glass frits dispersed in organic media.
Abstract: The present invention provides a thick-film paste composition comprising an electrically conductive metal and an oxide composition dispersed in an organic medium. The paste composition is printed on the front side of a solar cell device having one or more insulating layers and fired to form an electrode, and is suitable for devices having both highly and lightly doped emitter structures.
