Supplying the world with electricity from renewable sources is one of the greatest challenges of the 21st century. A decisive aspect is the effort to considerably reduce the costs of generating electricity from photovoltaics and to increase cell efficiencies. But it is still a long way to make this product competitive with conventionally generated electricity, in other words, to reach grid parity. Lasers as production tools offer a large potential for reaching these goals. Because of their spatially selective, contact-less and controllable processing characteristics, lasers are highly suitable for the production of sensitive components such as solar cells.

Laser soldering for cell interconnection is one of many applications of lasers in photovoltaics.

On May 25, 2011 the Fraunhofer Institute for Laser Technology ILT, together with the consortium of the European project SOLASYS, is hosting a workshop about Laser for Photovoltaics in Munich. In conjunction with the Laser 2011 World of Photonics event, experts from science and industry will present the latest research results and current applications, technological challenges and processing solutions for the precision machining of crystalline solar cells. All lectures will be held in English. Registration is now open. Please contact Dr. Schulz-Ruthenberg, Fraunhofer ILT directly (malte.schulz-ruhtenberg@ilt.fraunhofer.de).
