A laser scanning system by LIMO Lissotschenko Mikrooptik GmbH from Dortmund/Germany is able to support solar power system manufacturers with an enormous boost in productivity. The g2T scan system is, according to the company, the world's fastest "Gaussian-to-Top Hat" converter with integrated scanning technology.
Introduced in 2014, this potentially record-breaking complete solution for users in the photovoltaic industry is specially designed for laser direct structuring with single-mode lasers (532 nm). Thanks to its 160 by 160 mm² scan field (spot size of 75 x 75 µm²), the system is primarily suitable for use in the structuring of solar cells. This incredibly compact system is ideal for the ultrafast, high-precision laser structuring of six-inch solar wafers. Due in no small part to its extremely fast operation, the performance of this complete module is not only more accurate, but also more cost-effective than that of other systems.
Other highlights of the g2T scan system, which features a closed optical core with integrated galvo mirrors and a custom-made F-theta lens, include the quality of its written lines and the flexibility to freely program and quickly modify the cell design. "Our system will surely inspire manufacturers of solar energy equipment to come up with completely new ideas," says Klaus Reinecke, Vice President Sales at LIMO. "Some examples of possible processes would be the doping of selective emitters on silicon solar cells and the targeted opening of layers."
Interested companies have the opportunity to get to know more about this system at the International Congress on Applications of Lasers & Electro-Optics (ICALEO) in San Diego, CA, USA (October 19-23, 2014) or at the Glasstec trade show in Düsseldorf, Germany (booth 11A07 in Hall 11, October 21-24, 2014).
