Laser Marking

For product tracking and tracing, solar cells are endued with marks generated by solid-state lasers. The marking ought to be machine-readable, should not exert any influence on other fabrication steps and should, even at the end of the manufacturing process, enable doubtless identification. Besides alphanumeric symbols, data matrix codes and bar codes as well as manufacturer's logos can be generated. The size of the markings ranges from ***semi visible*** (with a font size of about 75 ��m) to an extension of several centimetres. The minimum font width amounts to 10 ��m.
