Imagine a jacket that produces enough electricity to charge your mobile phone. Imagine a jacket that does not only reflect, but light up itself when you ride your bike in the dark. Innovative printing solutions make future happen today. The Fraunhofer Institute for Applied Polymer Research IAP presents different prototypes from photovoltaics research projects at the international exhibition and conference for the printed electronics industry LOPEC 2018 in Munich, March 13 to 15. First projects resulting from the German OLED Technology Alliance (GOTA) are being presented as well.

Renewable energy has become an important topic in today’s society. Modern printing solutions promise the easy and cost efficient production of photovoltaics elements, even beyond architectural uses.
At LOPEC 2018 Fraunhofer IAP displays its competences, especially regarding inkjet-printing techniques. With these solutions, façade elements for the production of solar energy can be printed. Due to the printing technology used, these elements can be produced on a larger scale with reduced costs compared to conventional production methods.
Further applications can be found in optoelectronics and medicine. The process of printing is also applicable within the textile industry. Alongside a façade element the researchers display a jacket with photovoltaic elements which produces enough energy to charge a mobile phone and operate hand warming pads. The jacket even stores the energy. Currently the IAP-researchers are developing a solar powered LED-bicycle jacket together with industry partners.
The institute has its own pilot plant for printed electronics on which the displayed elements were produced. “On our pilot plant we develop printing solutions in a very industry-oriented way. Together with our clients we then implement these solutions into their large scale plants based on the expertise we gather through our pilot plant. We improve our printing methods constantly and individually adapt them to our customers’ needs”, Dr. Armin Wedel, head of the research division Functional Polymer Systems at the Fraunhofer IAP, explains.
For small scale surfaces the scientists are working on implementing a novel drop-on demand system: esjet-printing (electro static printing). This technology allows the use of a wider range of inks, especially essential for printing very fine structures. Widening the range of possible inks regarding their viscosity is a big step. Inkjet-printing sets limits to the used ink’s viscosity. With esjet-printing, fine metal grids with high transmission rates can be printed and thus replace conventional transparent ITO-electrodes in photovoltaics components.
The Fraunhofer IAP and the OLED Technology Alliance, GOTA
Fraunhofer-researchers also present first customer projects resulting from the GOTA alliance. The Fraunhofer IAP develops processes and materials for future OLED production facilities in close cooperation with the plant engineering companies MBraun Inertgas-Systeme GmbH in Munich, Notion GmbH in Schwetzingen and ARDENNE GmbH in Dresden. The four partners have formed the OLED Technology Alliance GOTA in order to offer the market turnkey OLED production facilities.
The Fraunhofer IAP has been conducting research on organic electronic systems for over 25 years and focuses on solution-processed devices used in OLEDs, QLEDs, OTFT, OPV, perovskite solar cells, sensors and actuators. Several processing technologies are available in a large clean room. These include spin coating, material evaluation in lab devices, advanced processing technologies, such as inkjet printing and high-precision slot die coating on a robot-controlled S2S pilot line for dimensions up to 150 mm x 150 mm, and various evaporation and encapsulation technologies.

DESY and MPSD scientists create high-order harmonics from solids with controlled polarization states, taking advantage of both crystal symmetry and attosecond electronic dynamics. The newly demonstrated technique might find intriguing applications in petahertz electronics and for spectroscopic studies of novel quantum materials.
The nonlinear process of high-order harmonic generation (HHG) in gases is one of the cornerstones of attosecond science (an attosecond is a billionth of a...
Nano- and microtechnology are promising candidates not only for medical applications such as drug delivery but also for the creation of little robots or flexible integrated sensors. Scientists from the Max Planck Institute for Polymer Research (MPI-P) have created magnetic microparticles, with a newly developed method, that could pave the way for building micro-motors or guiding drugs in the human body to a target, like a tumor. The preparation of such structures as well as their remote-control can be regulated using magnetic fields and therefore can find application in an array of domains.
The magnetic properties of a material control how this material responds to the presence of a magnetic field. Iron oxide is the main component of rust but also...
Due to the special arrangement of its molecules, a new coating made of corn starch is able to repair small scratches by itself through heat: The cross-linking via ring-shaped molecules makes the material mobile, so that it compensates for the scratches and these disappear again.
Superficial micro-scratches on the car body or on other high-gloss surfaces are harmless, but annoying. Especially in the luxury segment such surfaces are...
The Potsdam Echelle Polarimetric and Spectroscopic Instrument (PEPSI) at the Large Binocular Telescope (LBT) in Arizona released its first image of the surface magnetic field of another star. In a paper in the European journal Astronomy & Astrophysics, the PEPSI team presents a Zeeman- Doppler-Image of the surface of the magnetically active star II Pegasi.
A special technique allows astronomers to resolve the surfaces of faraway stars. Those are otherwise only seen as point sources, even in the largest telescopes...
Researchers at Chalmers University of Technology and the University of Gothenburg, Sweden, have proposed a way to create a completely new source of radiation. Ultra-intense light pulses consist of the motion of a single wave and can be described as a tsunami of light. The strong wave can be used to study interactions between matter and light in a unique way. Their research is now published in the scientific journal Physical Review Letters.
"This source of radiation lets us look at reality through a new angle - it is like twisting a mirror and discovering something completely different," says...
