Silicon solar cells and contacts thereof are printed in at least a two stage printing process where the busbars and fingerlines may be printed separately. A reduction in silver content in busbars and fingerlines through use of the techniques of the invention have been realized, including the use of certain base metals, while maintaining low contact resistance similar to silve pastes.
