Heavy Duty Laser Machining of EWT Solar Cells
Highest throughput at extreme precision
Laser drilling of micro holes for back-contacts
3D-Micromac AG, leading supplier of tailored laser micromachining systems, announces the launching of a dedicated workstation for back-side contacting of emitter wrap-through (EWT) solar cells. The novel machining concept is based on the approved microDrill family.
Driven by the Renewable Energy Sources Act, solar industry is scrutinizing ever more effective ways to directly convert solar energy into electric current. The resulting technological stimulus advances the application of particularly flexible tools for micro structuring. For edge isolation as well as selective ablation of layers in the fabrication of thin-film solar cells, laser micromachining techniques are already well-established. Moreover, laser drilling proved predestined for the highly efficient generation of micro holes in EWT solar cells.
Staying abreast of these changes, 3D-Micromac AG advanced the approved microDRILL system. Utilizing an 80 W infrared laser, 5,000 clearance holes can be drilled per second. Their exact alignment at a repeat accuracy of 5 µm is achieved by edge and mark recognition.
Therewith, the preconditions for the generation of micro holes during an industrial-scale fabrication of EWT solar cells are given. Tino Petsch, CEO of 3D-Micromac AG says: „With immediate effect, our customers also in this range do benefit from our long-standing experience in the development of industrial laser micromachining workstations.”
