Patent ID: 8065784

Claim:
A bonding wire attach module, comprising: a substrate handling system having a conveyor system configured to receive a solar cell substrate into the bonding wire attach module and transfer the solar cell substrate out of the bonding wire attach module; a positioning system having a vision system comprising a camera, wherein the vision system is configured to scan the solar cell substrate and send signals regarding the position of one or more features on the solar cell substrate to a system controller; a cross-buss assembly having a motion assembly configured to receive commands from the system controller and position cross-buss material across a back contact surface of the solar cell substrate such that the cross-buss material is insulated from the back contact surface of the solar cell substrate; and a side-buss assembly configured to position and affix side-buss material to the back contact surface of the solar cell substrate along an edge region of the solar cell substrate, wherein the side-buss material electrically connects the edge region of the solar cell substrate to the cross-buss material.
