  • Patent number: 8216483
    Abstract: A super water repellent surface is prepared by arranging plural spherical beads on a substrate surface to form a (N)-th bead layer, etching the substrate surface with the (N)-th bead layer as an etching mask, arranging plural spherical beads, which are larger than the (N)-th beads in diameter, on the substrate surface to form a (N+1)-th bead layer, etching the substrate surface with the (N+1)-th bead layer as an etching mask, removing the beads from the etched substrate surface and coating a fluorine compound on the substrate surface on which a hierarchical concavo-convex structure has been formed. The (N+1)-th bead layer forming step and the (N+1)-th etching step are repeated N times.

  • Publication number: 20090032107
    Abstract: The present invention relates to an organic solar cell made of a transparent conductive polymer electrode and a fabricating method thereof. An anode electrode is formed on a substrate, a photoactive layer is formed on the anode electrode, and a cathode electrode is then formed on the photoactive layer. The anode electrode is formed by stacking conductive polymer particles by an electrostatic spray printing method, and a micro pattern is formed on the substrate before forming the anode electrode. The micro pattern is formed by hot embossing, the photoactive layer is formed by gravure printing or spin coating, and the cathode electrode is formed by screen print or evaporation deposition. A series of processes for fabricating an organic solar cell is performed using a roll-to-roll process.

  • Publication number: 20060254440
    Abstract: Disclosed herein is a method and apparatus for manufacturing an electronic device, which is intended to economically manufacture an electronic circuit device, such as an IC chip, using functional ink and a roll-to-roll rotary pressing process. The method includes a first step of injecting functional ink into a forming groove of a forming roll, a second step of removing ink covering a surface of the forming roll, a third step of drying a surface of the functional ink injected into the forming groove, a fourth step of transferring the dried surface of the functional ink to a printing roll, a fifth step of drying another surface of the functional ink transferred to the printing roll, a sixth step of transferring the functional ink from the printing roll to flexible printing paper which is unwound from a winding roll, and a seventh step of winding the printing paper, on which an electronic circuit is printed, around a rewinding roll.
