Marking on silicon wafers in solar cells
Solar cells manufacturers deal with Polycrystalline Silicon which is highly sensitive to mechanical stress. Traceability data must be hidden in corners and must be marked in the smallest surface possible. Direct laser marking is the solution to increase productivity and throughput. It is possible to mark 1mm 14x14 2D codes. A 10W laser marker running at 532 nm wavelength, achieves both speed and quality.
