  • Multi-layer sputtered metal seed for solar cell conductive contact
    Patent number: 10164131
    Abstract: Multi-layer sputtered metal seed for solar cell conductive contacts and methods of forming solar cell conductive contacts are described. In an example, a solar cell includes a substrate. A semiconductor region is disposed in or above the substrate. A conductive contact is disposed on the semiconductor region and includes a seed material stack in contact with the semiconductor region. The seed material stack includes a first aluminum layer having a first crystallinity and disposed on the semiconductor layer, and a second aluminum layer having a second crystallinity and disposed on and having an interface with the first aluminum layer. The first crystallinity is different from the second crystallinity.
    Type: Grant
