This Innolas ILS 700P system has been used exclusively in production for laser edge isolation of solar cells.
Basically, the need for edge isolation arises from the ion doping/diffusion step of the c-Si cell manufacturing process, in which a shallow (~μm’s) layer of the bulk p-type silicon is infused with negatively doped ions (Phosphorus Doping). This doped region surrounds the entire wafer, and causes electrical shunting between
the front and back electrical contacts without the isolation scribe.
Laser edge isolation is typically achieved by scribing a groove around the perimeter of the solar cell, as close to the edge of the wafer as possible. The groove depth must extend some distance beyond the ion diffusion layer in order to give the best result. Typical groove dimensions are 20–40 μm wide x 10–20 μm deep.

This system is fitted with a Coherent Avia-355-X laser, which has a nominal repetition rate programmable between 40 kHz and 120 kHz and a short pulse width in the ns range, which when coupled with high-speed scanning galvanometer technology, achieves edge isolation times  in the 1–2 second range for 156 mm wafers. Depending on the system optical design (spot size, etc.), isolation scribes can be machined at speeds from 500–1000 mm/sec or higher.
