In order to reduce production costs and to increase throughput, great efforts have been put to explore efficient processing in full-automated manufacturing lines. Because of non-contact processing and high flexibility the use of lasers in photovoltaic production has grown in popularity, for example laser fired contact, drilling contact holes, edge isolation, scribing, edge deletion, etc. Different application needs different laser parameters such as wavelength and beam profiles.
