Abstract
A method is disclosed for passivating and contacting a surface of a germanium substrate. A passivation layer of amorphous silicon material is formed on the germanium surface. A contact layer of metal is then formed on the passivation. The structure is heated so that the germanium surface makes contact with the contact layer. Thus, a passivated germanium surface is disclosed, as well as a solar cell comprising such a structure.
