Claim Text:
1. A method for metallizing a solar cell, the method comprising: coating a first region of the solar cell with a first solar cell screen-printing composition, the first solar cell screen-printing composition comprising at least aluminum and silicon, a percentage by mass of the silicon lying in a range from approximately 5% to approximately 30% of a sum of percentages by mass of silicon and aluminum; coating a second region of the solar cell, which adjoins the coated first region, with a second solar cell screen-printing composition which is substantially free of silicon, wherein the first and second solar cell screen-printing compositions on the first region and the second region are connected to one another in an electrically conductive manner; heating the solar cell coated with the first and second solar cell screen-printing compositions; and after the heating of the solar cell, an additional layer, which contains a solderable material, being applied directly on or directly over at least the first solar cell screen-printing composition.
