Method and arrangement for the production or repair of a solar module

The invention relates to a process for producing a solar module from a plurality of by cell connectors (9a; 9b) connected in series solar cells, wherein the cell connectors are mechanically fastened to the solar cells by soldering and contacted with the busbars electrically, wherein the cell connectors prior to the soldering by means of spraying a solderable alloy or highly reflective coating are treated in a plasma spray, thermal spray or cold gas spraying method in connecting areas, and then soldered onto the busbars. It relates to an arrangement for performing this method.
