Abstract

See full text

For contacting a silicon solar cell a pre-processed silicon substrate with a frontside and a backside is provided. Then, aluminum is deposited on the backside of the pre-processed silicon substrate, wherein aluminum-free regions remain on the backside. Then, a silver-free layer suitable for soldering on the backside of the silicon substrate is deposited so that the silver-free layer suitable for soldering covers at least the aluminum-free regions on the backside.
