Laser processing has been shown to be a versatile and cost-effective technology for such applications. Local silicon doping or contact opening via ablation are two established process steps. In this work, we investigate their influence on the quality of local contacts with a focus on contact resistivity. We determine values for ρC down to 70 μΩ cm2 and 30 μΩ cm2 for phosphorus and boron respectively, on a simple test structure with the help of three-dimensional numerical simulations.J.D.H acknowledges funding by the center of renewable energy of the University of Freiburg, within the interdisciplinary graduate school “DENE”.application/pdfen-AU© 2018 IEEEContact openingcontact resistivitylaser ablationlaser dopingmetallizationsilicon201810.1109/PVSC.2018.85472092022-10-02
