Innovation award for sollar cell processing workshop SOLLAS

Dec. 10, 2010 - PRLog -- Sollas  is an industrial-research laser machine for c-Si solar cells. Equipped with cutting edge duet - femtosecond UV laser and nanosecond IR laser, Sollas is a multi-tasking system, designed for industrial-research or up to 3 MW/a capacity pilot manufacturing lines. Main advantages of this femtosecond laser are precision in ablation process due to selective absorption and minimal heat affected zone.
Sollas workstation is optimized to perform four technological operations based on laser scribing, laser selective ablation and laser selective melting:
•   selective SiNx SiO2 removal for emitter contact formation;
•   back contact laser firing;
•   edge isolation;
•   laser marking.
