Dr. Ralf Preu, Fraunhofer ISE: Prize Winner of the Innovation Award Laser Technology 2014

08.05.2014

The Innovation Award Laser Technology 2014, initiated by the associations Arbeitskreis Lasertechnik e.V. and the European Laser Institute ELI and provided with 10 000 Euros prize money, has been conferred to Dr. Ralf Preu, director of the division “Photovoltaics – Production Technology and Quality Assurance” of the Fraunhofer Institute for Solar Energy Systems ISE in Frei-burg (Germany) on 7th May 2014 in Aachen´s town hall. Dr. Ralf Preu and his team have got the first place in the open prize competition with the innovation “Laser Fired Contact (LFC) technology for the production of highly efficient silicon solar cells”.

The jury composed by 9 international experts has selected 3 finalists among the 23 submitted applications. In the historical ambience of the »Coronation Hall« around 300 guests attended the awarding ceremony. Dr. Paul Hilton, speaker of the international jury, pointed out the dedicated work of all 3 finalist´s and the outstanding innovations of the project teams in the field of laser technology.

The jury conferred the 1st prize of the Innovation Award Laser Technology 2014 provided with 10 000 € prize money to Dr. Ralf Preu, director of the division “Photovoltaics – Production Technology and Quality Assurance” of the Fraunhofer Institute for Solar Energy Systems ISE in Freiburg (Germany) and his team for the innovation “Laser Fired Contact (LFC) technology for the production of highly efficient silicon solar cells”.

By the use of the LFC process the industrial partner set several technological world records. Regarding cell and module efficiencies 19,5% for a large area multi-crystalline silicon solar cell and 18,5% for a standard sized module were achieved. In the meantime approximately 1 million photovoltaic modules with Laser Fired Contacts are produced and installed.

The outstanding performance of these modules compared to standard technology has been confirmed in several field tests. The Fraunhofer ISE in Freiburg is an institute of the Fraunhofer Gesellschaft and contributes with its 1300 strong workforce and the cooperating industrial partners to innovations for a more efficient and environmentally friendly energy supply.

The prize winner Dr. Ralf Preu has been awarded the title of »AKL Fellow« and »ELI Fellow«. The certificates for the first, second and third placed finalist teams were handed over by Dipl.-Ing. Ulrich Berners, president of the Arbeitskreis Lasertechnik AKL e.V. and Dr. Paul Hilton, president of the European Laser Institute ELI.

The Innovation Award Laser Technology is a European research prize awarded at 2-yearly intervals by the associations Arbeitskreis Lasertechnik e.V. and the Euro-pean Laser Institute ELI. The award can be conferred on an individual researcher or on an entire project group, whose exceptional skills and dedicated work have led to an outstanding innovation in the field of laser technology. The scientific and technolo-gical projects in question must center on the use of laser light in materials processing or the methods of producing such light, and must furthermore be of demonstrable commercial value to industry.

Im Focus: UNH scientists help provide first-ever views of elusive energy explosion

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.

Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...

Im Focus: A Chip with Blood Vessels

Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.

Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...

Im Focus: Penn engineers develop ultrathin, ultralight 'nanocardboard'

When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure

Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...
