  • Passivation process
    Patent number: 11621366
    Abstract: A passivation process includes the successive steps of a) providing a stack having, in succession, a substrate based on crystalline silicon, a layer of silicon oxide, and at least one layer of transparent conductive oxide; and b) applying a hydrogen-containing plasma to the stack, step b) being executed at a suitable temperature so that hydrogen atoms of the hydrogen-containing plasma diffuse to the interface between the substrate and the layer of silicon oxide.
    Type: Grant

  • PHOTOVOLTAIC CELL COMPRISING A REGION SUSPENDED BY A CONDUCTIVE PATTERN AND PRODUCTION PROCESS
    Publication number: 20130037101
    Abstract: The photovoltaic cell includes an electrically conductive passivation film separated from an electrically conductive collection layer and a substrate. An electrically conductive connection pattern maintains an area of the collection layer in suspension with respect to the passivation film. Suspension of the collection layer is obtained by making an etching agent pass through a permeable area of the collection layer.
