ABSTRACT:
An apparatus for both detecting and repairing a shunt defect in a solar cell substrate. A shunt detection module detects the shunt defect in the substrate, using at least one of lock-in thermography and current-voltage testing. A process diagnostic module determines whether the substrate should be passed without further processing by the apparatus, rejected without further processing by the apparatus, or repaired by the apparatus. A shunt repair module electrically isolates the shunt defect in the substrate. In this manner, a single apparatus can quickly check for shunts and make a determination as to whether the substrate is worth repairing. If it is worth repairing, then the apparatus can make the repairs to the substrate.
