Abstract: Apparatus (1) for manufacturing solar cell matrices includes several stringers (2) for forming strings from solar cells, a lay-up and interconnection station (5) for arranging and interconnecting the strings to form a solar cell matrix, and a transportation system (3) for transferring the strings from the stringers (2) to the lay-up and interconnection station (5), wherein the stringers (2) are arranged perpendicular to the direction of flow of the transportation system (3), or in an acute angle to an axis perpendicular to the direction of flow of the transportation system (3). Furthermore, a process for operating such apparatus (1), wherein the several stringers (2) are controlled such that collision between different strings is avoided in the transportation system (3).

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.
