The present invention provides methods and apparatus for deposition of contact layers for Group IBIIIAVIA solar cells using electrodeposition and/or electroless deposition approaches, and solar cells that result therefrom. In one aspect of the invention, the solar cell that results includes a substrate, a stacked contact layer that includes a bottom film coated on a surface of the substrate and a top film formed by electroplating over the bottom film, wherein the top film comprises at least one of Ru, Ir and Os. A Group IBIIIAVIA compound film formed over the top film. In another aspect of the invention, there is provided a method of depositing a stacked layer of a plurality of films in a plurality of sequentially disposed depositing units onto a continuously moving roll-to-roll sheet, preferably using electroplating of a stacked contact layer.
