The effects of near-infrared laser induced ablation on thin-film solar
cells were investigated. As a result, a modelling approach for the
described material deletion process is suggested. Analyses of optical
behaviour of the irradiated layers and their interfaces as well as
experiments on ablation threshold determining parameters to validate the
modelling approach were observed. Thereby the interaction of pulse duration
and overlapping with respect to the threshold behaviour has been examined.
The submitted contribution promotes laser process development and laser
resonator optimisation as well.
