Jenoptik Lasers & Material Processing Div. has released the Jenoptik-Votan Solas 1800, a laser system that drills within 1 s up to 100 tiny through holes into crystalline solar cells for back-side contacts via metal or emitter wrap-through technology. Available as a stand-alone system or as a module for integration into existing production environments, it has a disk laser that creates <10-μm holes without microcracks or debris. The laser beam is delivered by a scanner, with positioning accuracy of ±10 μm. Wafer sizes of 100, 125 and 156 mm can be accommodated, as can wafer thickness from 150 to 300 μm. Up to 1800 solar cells can be processed per hour.
