Abstract: Process and apparatus for providing a solar cell (2) with a solder ribbon (3), the cell (2) having at least one bus bar (7), wherein flux (4, 4a-4d) is applied by an automatically controlled spray head (5, 6), and the solder ribbon (3) is connected to a bus bar (7) by an automatically controlled soldering unit. Flux (4, 4a-4d) is only applied to locations of the ribbon (3) to be connected to the bus bar (7) and/or flux (4, 4a-4d) is only applied to those locations of the bars (7) to be connected to the ribbon (3). A solar cell (2), that has at least one bus bar (7), with a solder ribbon (3), may be provided by such apparatus and processes.
