Claim 0:
1. A method of electrically coupling solar cells, the method comprising:
aligning conductive wires over back sides of adjacent solar cells, wherein the conductive wires are aligned substantially parallel to P-type and N-type doped diffusion regions of the solar cells, and wherein aligning the conductive wires comprises using a wire support included in a system for stringing solar cells;
bonding the conductive wires to the back side of each of the solar cells over the P-type and N-type doped diffusion regions, wherein bonding the conductive wires comprises using a welder included in the system for stringing solar cells, the welder downstream from and vertically beneath the wire support in the system for stringing solar cells;
subsequent to bonding the conductive wires to the backside of each of the solar cells, cutting every other one of the conductive wires between each adjacent pair of the solar cells, wherein cutting every other one of the conductive wires comprises using a first cutter included in the system for stringing solar cells, the first cutter downstream from the welder in the system for stringing solar cells; and
subsequent to cutting every other one of the conductive wires, severing all of the conductive wires at an end of a solar string, wherein severing all of the conductive wires comprises using a second cutter included in the system for stringing solar cells, the second cutter downstream from the first cutter in the system for stringing solar cells.
