LOPEC 2016: Laser innovations for structuring and ablating in organic electronics

10.03.2016

The Fraunhofer Institute for Laser Technology ILT will be presenting laser innovations for printed and organic electronics to an audience of industry professionals at the LOPEC 2016 trade fair in Munich on April 6-7, 2016. The presentation will show the laser structuring processes used for flexible organic electronics and OLED technology.

For several years now, the electronics and other industries have been abuzz about an entirely new spectrum of applications below the familiar field of silicon technology. The object of all this excitement is organic and printed electronics, which make it possible to produce thinner, lighter and more flexible components. Application areas for this pioneering new technology include lighting elements, TV and cell phone displays, photovoltaics and intelligent packaging such as RFID tags.

Fraunhofer ILT inscribes OLEDs

The LOPEC (Large-area, Organic & Printed Electronics Convention) trade fair in Munich is the leading exhibition for printed electronics worldwide with the most important conference, according to its organizers, and it has been presenting the latest developments in the field for seven years now.

Fraunhofer Institute for Laser Technology ILT has responded to the significance of this venue, working in cooperation with COPT NRW to exhibit its research developments, which support companies in the manufacturing of new components using organic and printed electronics. Currently, Fraunhofer ILT is developing a method for adding inscriptions to OLED components.

“We have succeeded in producing an inscription in the illumination surface by means of selective deactivation of organic material,” explains Fraunhofer ILT researcher Christian Hördemann. “We use a laser beam activated in ultrashort pulses. Together with our partner company OLEDWorks, we are working on developing a novel process to achieve long-term stable inscription and customization of OLEDs.”

An additional focus of their work entails laser microstructuring. The benefits of this process include its high resolution in the µm range, its high throughput for large surfaces, and its wide range of design possibilities.

Laser structuring for flexible solar cells

In Munich, Fraunhofer ILT will be showcasing additional applications involving laser microstructuring of extremely thin layers to demonstrate how the properties of organic components can be influenced using this technology. Picosecond lasers, for instance, can be used for roll-to-roll production of organic solar cells. Processes for the roll-to-roll production of organic solar cells are being researched in collaboration with Coatema Coating Machinery GmbH from Dormagen and Solarmer Energy, Inc. from the US. A good example of this method being used in production is the “Mini Module” flexible solar cell.

“At the moment we have achieved efficiency over 6% by using laser patterned ITO in the fabrication of our mini-sized flexible OPV modules,” explains Dr. Yanping Wang, Principal Researcher at Solarmer Energy, Inc. “Our flexible OPV enables versatile designs for applications that were not possible before, especially the low-power application in the rapidly emerging wearable electronics and Internet of Things markets.”

Further information and additional laser innovations for printed and organic electronics will be on hand at the joint booth of COPT NRW and Fraunhofer Institute for Laser Technology ILT at the LOPEC exhibition on April 6-7, 2016 in Munich (hall B0, booth 404).

Im Focus: A Challenging European Research Project to Develop New Tiny Microscopes

The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.

To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...

Im Focus: Giant Magnetic Fields in the Universe

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.

The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.
