Part of:

This publication presents the highly selective laser ablation of functional ~110…250 nm layers of novel flexible organic photovoltaics (P2 and P3) as well as decorative coatings by short and ultra-short pulsed laser systems with UV, GR and IR wavelengths. Main focus is on the structuring without damaging the subjacent ultra-barrier layer and substrates. Spatial beam shaping is utilized for process optimization. Characterization of the processing results is realized by different techniques such as the optical Ca-test as the “gold standard” and Hyperspectral imaging (HIS) as a novel, fast and contact-free method.
