The interaction of laser light with silicon — •Aart Schoonderbeek, Oliver Haupt, Rainer Kling, and Andreas Ostendorf — Laser Zentrum Hannover e.V. (LZH), Hannover

During the last years, the photovoltaic industry has experienced enormous growth. However, for solar cells to be competitive on the longer term, both an increase in their efficiency as well as a reduction in costs is necessary. According to these demands, laser technology offers many possibilities to develop new processes and is even a key-technology for many novel solar cell designs. This presentation gives an impression of laser processing of the most important material in this field: silicon. Different laser types and some of the most important laser parameters for silicon processing, like the pulse duration and the wavelength, are discussed.
