LPKF CIGS Laser Technology

LPKF has developed special processes for laser scribing the CIGS solar modules in steps P2 and P3 and has further optimized laser structuring in step P1. Their aim is to remove additional functional layers between the glass and molybdenum without damage, avoid the disadvantages of mechanical tools and noticeably reduce the dead zone.

The molybdenum structuring in P1 sets new challenges for laser processing due to new coating systems, including diffusion barrier layers. Structuring (scribing) with short-pulse lasers through the substrate delivers outstanding results here. The slightly more expensive short-pulse lasers can be used cost-efficiently in the LPKF Allegro laser scribers.
