Laser Processing

The main emphasis of our research lies on the further evolution of laser processes  for high-efficiency and low-cost back-contact crystalline silicon solar cells.  We optimize our laser processes like laser-doping, laser-ablation and -structuring of thin films, as well as laser-welding of metal foils for contacting, in close collaboration with the research groups “Industrial Solar Cells” and “Semiconductor Technology” at ipv. Furthermore, we analyze laser-annealing processes for dopant-atom activation in semiconductor materials, as well as the laser-porosification of sputtered silicon layers for the fabrication of porous anodes in lithium ion batteries.
