Titel
A modelling approach for an edge deletion process of thin-film solar cells with high-power nanosecond laser radiation
Abstract
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.
