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.”

Our experts at LOPEC 2016

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: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

Im Focus: Fraunhofer ISE Develops Highly Compact, High Frequency DC/DC Converter for Aviation

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.

Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
