Abstract
Metal seed layers for solar cell conductive contacts and methods of forming metal seed layers for solar cell conductive contacts are described. For 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 layer in contact with the semiconductor region. The seed layer is composed of aluminum (Al) and a second, different, metal.
