Patent ID: 8129658

Claim:
A system for fabricating a solar-cell assembly, the system comprising: a support mechanism for receiving a workpiece comprising a substrate and a first layer; at least one laser device each configured to direct a laser beam toward the workpiece; and a laser controller operable to cause the at least one laser device to: scribe a plurality of first interconnect lines into the first layer, after a second layer is deposited onto the first layer and into the first interconnect lines, scribe a plurality of second interconnect lines into the second layer, wherein each of the second interconnect lines is located adjacent to one of the first interconnect lines, and wherein each second interconnect line is contiguous, after a third layer is deposited onto the second layer and into the second interconnect lines, scribe a plurality of third interconnect lines into the second layer and the third layer, wherein each of the third interconnect lines is located adjacent to one of the second interconnect lines, and scribe a plurality of isolation lines into the first, second, and third layers.
