  • Enhanced adhesion of seed layer for solar cell conductive contact
    Patent number: 9263601
    Abstract: Enhanced adhesion of seed layers for solar cell conductive contacts and methods of forming solar cell conductive contacts are described. For example, a method of fabricating a solar cell includes forming an adhesion layer above an emitter region of a substrate. A metal seed paste layer is formed on the adhesion layer. The metal seed paste layer and the adhesion layer are annealed to form a conductive layer in contact with the emitter region of the substrate. A conductive contact for the solar cell is formed from the conductive layer.
    Type: Grant
