Jenoptik plans disk laser debuts at EU PVSEC

The Jenoptik Lasers & Material Processing division will launch the JenLas IR50E/IR70E infrared disk lasers for micro-material processing of crystalline solar cells at EU PVSEC.

August 18, 2011 — The Jenoptik Lasers & Material Processing division will launch the JenLas IR50E/IR70E infrared disk lasers for micro-material processing of crystalline silicon (c-Si) solar cells at European Photovoltaic Solar Energy Conference and Exhibition (EU PVSEC), September 5-8 in Germany.

The JenLas IR50E/IR70E infrared disk lasers have independently adjustable laser parameters for the photovoltaics manufacturing. Laser pulse lengths can be adjusted independently of repetition rate and laser power.

The extended-version lasers (E = extended) have shorter pulse lengths, significantly higher repetition rates and constantly high pulse energies, Jenoptik reports. Interfaces are standardized for Jenoptik.

The disk lasers can be used to fabricate laser-fired contacts (LFC, up to 25,000 contacts per second), metal wrap through (MWT), emitter wrap through (EWT) and laser edge isolation (LEI) photovoltaics manufacturing structures.

Jenoptik will also bring its diode-pumped femtosecond laser JenLas D2.fs. The laser emits high-pulse-energies and can be operated in the high repetition range. Jenoptik will discuss the laser’s selective single layer removal ability for multi-layer, multi-material PV cells. Also at EU PVSEC booth B9, hall A1, will be the JENOPTIK-VOTAN Solas 1800Laser for crystalline-silicon solar cell production in a modular design and JENOPTIK-VOTAN Solas MultiSerial for lab-scale and pilot large-format thin-film solar cell production that can scale to commercial use.

The Lasers & Material Processing division of JENOPTIK Laser GmbH provides laser material processing tools. Learn more at www.jenoptik.com/pvsec2011.
