  • Patent number: 8368163
    Abstract: A semiconductor component, especially a solar cell comprises a semiconductor substrate of a planar design having a first side and a second side lying opposite thereto, at least one contact structure arranged on at least one side of the semiconductor substrate, the at least one contact structure exhibiting a diffusion barrier to prevent the diffusion of ions from the contact structure into the semiconductor substrate.
    Type: Grant
    Filed: September 25, 2009
    Date of Patent: February 5, 2013
    Assignee: SolarWorld Innovations GmbH
    Inventors: Andreas Krause, Martin Kutzer, Michael Heemeier, Alexander Fülle, Holger Neuhaus
  • Publication number: 20100219535
    Abstract: A method for producing a semiconductor component with an easily solderable contact structure comprising the provision of a semiconductor substrate of a planar design with a first side, a second side, a surface normal standing vertically thereon, a dielectric passivation layer arranged on at least one of the sides and a first contact layer arranged on passivation layer, the application, at least in some areas, of at least one second contact layer onto the first contact layer, the at least one second contact layer comprising at least a partial layer made of an easily solderable metal, especially of nickel and/or silver and/or tin and/or a compound thereof, and the making of an electrically conductive contact between the second contact layer and the semiconductor substrate.
