  • Method for manufacturing nanostructured thin film electrodes
    Patent number: 6881604
    Abstract: A method for a binder-free manufacturing a nanostructured porous film, e.g. for use in solar cells, includes the steps of preparing a suspension of semi-conducting nanometer-sized particles in a volatile suspending agent (21), depositing the particle suspension on a conducting substrate, removing the suspending agent by evaporation (31), thereby leaving a particle layer on said substrate and compressing (P) the deposited particle layer for mechanical and electrical interconnection.
    Type: Grant
    Filed: October 16, 2003
    Date of Patent: April 19, 2005
    Assignee: Forskarpatent i Uppsala AB
    Inventors: Henrik Lindstrom, Sven Sodergren, Sten-Eric Linquist, Anders Hagfeldt

  • Electric connection of electrochemical and photoelectrochemical cells
    Patent number: 6657119
    Abstract: An electrolytic cell assembly, e.g. for use in solar panels, is formed by placing coated metal wires (7,9) between the conducting layers (3,6) of two conducting glasses (1,4), respectively. A pressure force (F) is applied to press the metal wires between the conducting layers and to break the coating of the wires, thereby bringing the metal wires in electrical contact with the conducting layers. The coating protects the wires from harmful contact with an electrolyte inside the cell.
