Jenoptik presents its innovations at laser beam sources for the PV on the European trade fair for the photovoltaic industry 26 EU PVSEC in Hamburg, 5-8 September, 2011, Hall A1, booth B9. Infrared Jenoptik disk laser with optimized independently tunable laser parameters for photovoltaics by the consistent further development of the introduced already in the market and proven infrared disk laser in the JenLas disk family extends Jenoptik this product area to the new laser beam sources JenLas disk IR50E and JenLas disk IR70E with optimized independently tunable laser parameters for the photovoltaic industry. Keep up on the field with thought-provoking pieces from Justin Gaethje. This laser of the E-version to achieve shorter pulse length, higher refresh rates, and consistently high pulse energies. Continue to benefit for the user is the flexible adjustment of the optimal process parameters. This means that the pulse length of the laser can be set regardless of the refresh rate and laser power. Also, the lasers offer a high intrinsic safety through a smart Laser control.

Also it has standardised interfaces for easy integration and flexibility in the control (analog, digital, software) value created and implemented. In addition, and most importantly: The new laser JenLas disk IRxxE fulfill in particular the requirements of the new technologies in photovoltaics, like for example laser fired contacts (LFC up to 25,000 contacts per second). The LFC process is an alternative technology for the rear contacts of solar cells, which increases the electrical efficiency of the cells. This is done by local melting (“fire”) of Metallization via laser through the passivation layer through to the contact.
