Ultrafast laser-based selective removal of self-assembled Ag network electrodes on PET substrates is demonstrated to be an effective patterning method at a high pulse repetition rate in the heat accumulation regime. The Ag network was completely removed, not only by direct laser ablation, but also by efficient delamination of the Ag network from the substrate, which is result of the local heat accumulation...
An ultrafast laser was used to ablate transparent conducting layers deposited either by multilayered silver and ITO or silver web. Performance of the devices using them as electrodes was examined to confirm the process' efficiency.
Ultrafast laser based materials processing has shown remarkable success in various area of industrial applications. A few examples of innovative applications in displays, OSCs, and other consumer electronics fabrication are demonstrated.
Maximization of the ablation rate of various materials was investigated by optimization of ultrafast laser parameters. The optimized parameters were used to engrave metal roles for micron-sized pattern transfer of conductive ink to flexible substrates.
