  • Patent number: 6706961
    Abstract: A photovoltaic device having a first electrode comprising a metallic wire, a second electrode connected to the first electrode, and a joint portion composed of conductive particles and a resin. The joint portion is arranged between the metallic wire constituting the first electrode and the second electrode. A volume density of the conductive particles in the joint is decreased in a direction from a surface of the second electrode to a surface of the metallic wire constituting the first electrode.
    Type: Grant
    Filed: June 1, 2001
    Date of Patent: March 16, 2004
    Assignee: Canon Kabushiki Kaisha
    Inventors: Koichi Shimizu, Tsutomu Murakami, Kouji Tsuzuki
  • Patent number: 6586270
    Abstract: A process for producing a stable photovoltaic element having an electrode structure comprising a collecting electrode and a metal bus bar which are connected to have an improved connection between them. Said electrode structure is formed by dotting an electrically conductive paste onto a metal wire as the collecting electrode such that a dotted electrically conductive paste has an elliptical form whose major axis and minor axis are respectively perpendicular to and parallel to a lengthwise direction of said metal wire, arranging the metal bus bar on said dotted electrically conductive paste, and heating the resultant while pressing it to cure the electrically conductive paste to form connection between the metal wire as the collecting electrode and the metal bus bar.
