Abstract
Laser processing of crystalline silicon solar cells has basically been limited to the edge isolation process for standard screen-printed structures. In this paper the potential of some further steps like selective ablation of dielectric layers, ablation of silicon material, laser doping and the generation of laser-fired contacts, which are currently under investigation at Fraunhofer Institute for Solar Energy Systems (ISE) is explained by either theoretical considerations or experimental results. Furthermore, a quick overview over the current laser sources and their applicability in the crystalline silicon solar cell market is given.
