  • Publication number: 20150090327
    Abstract: A solar cell can include a substrate and a semiconductor region disposed in or above the substrate. The solar cell can also include a conductive contact disposed on the semiconductor region with the conductive contact including a paste, a first metal, and a first conductive portion that includes a conductive alloy formed from the first metal at an interface of the substrate and the semiconductor region.
    Type: Application

  • Publication number: 20150090325
    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.
