Electroluminescence mapping provides an elegant and powerful way to determine defects and cracks in complete solar cells. The electroluminescence mapping system at the Solar Power Laboratory uses a high resolution 8.3 Megapixel camera. The equipment is set-up for electroluminescence inspection of complete solar cells made on wafer sizes of up to 6 inches square. Also, a detailed analysis of spatial variation of series and shunt resistance from electroluminescence imaging is routinely performed at the Solar Power Laboratory.
