| description | According to the embodiments provided herein, a method for scribing a layer stack of a photovoltaic device can include directing a laser scribing waveform to a film side of a layer stack. The laser scribing waveform can include pulse groupings that repeat at a group repetition period of greater than or equal to 1.5 μs. Each pulse of the pulse groupings can have a pulse width of less than or equal to 900 fs.
Selon les modes de réalisation de la présente invention, un procédé de traçage d'un empilement de couches d'un dispositif photovoltaïque peut consister à diriger une forme d'onde de traçage laser vers un côté film d'un empilement de couches. La forme d'onde de traçage laser peut comprendre des groupements d'impulsions qui se répètent à une période de répétition de groupe supérieure ou égale à 1,5 µs. Chaque impulsion des groupements d'impulsions peut avoir une largeur d'impulsion inférieure ou égale à 900 fs. |
