Munich, Germany - Messe München has published a white paper that discusses how lasers, including CO2 lasers and laser cutters, are changing the photovoltaic manufacturing process. For example, laser ablation can take the place of common die etching. Laser drilling can create previously-impossible microholes in silicon substrates.
"How Lasers Are Changing Photovoltaic Manufacturing" discusses the changes brought about by the use of various types of lasers that process photovoltaic cells. Q-switched diode-pumped solid-state lasers, gas lasers, Erbium-doped fiber lasers are used to perform laser assisted doping, create laser fired contacts and emitter wrap-through vias, solder metal stringers and laser scribe the dies.
The free white paper, "How Lasers Are Changing Photovoltaic Manufacturing," is available for download from the LASER World of PHOTONICS website (click on "English") .
LASER World of PHOTONICS is regarded as the home base of the photonics industry. According to a survey conducted by Infratest, 98% of exhibitors and 97% of visitors were extremely satisfied with the last trade fair and intend to return in 2011. In addition to business objectives, the cultivation of contacts in the industry plays a very important role for all participants.
This year will feature four focus topics: "Lasers and laser systems in production", "Green photonics", "Biophotonics and life sciences", and "Security and defense".
LASER World of PHOTONICS has been held every two years since 1973. In 2009, it attracted 1,034 exhibitors and 25,365 visitors. The number of exhibitors and visitors from outside Germany has risen continuously and is presently 57% for exhibitors and 51% for visitors.
