  • OLED microdisplays have so far been developed predominantly on 200mm wafers. These conventional CMOS technologies and the associated backplane design have limited the number and size of pixels until now. At the Fraunhofer Institute for Organic Electronics, Electron Beam and Plasma Technology FEP, OLED microdisplays have been realized for the first time in a 28-nanometer backplane technology on 300mm wafers within the "Backplane" project funded by the Saxon State Ministry of Economics, Labor and Transport (SMWA). Components with a display diagonal of 0.18 inches and pixel sizes of only 2.5 micrometers have been manufactured. This corresponds to a pixel density of 10,000 dpi – an as-yet unattained level in the global OLED microdisplay market. These unique OLED microdisplays will be presented for the first time at SID Display Week, May 23–25, 2023, at the German Joint Booth, No. 1110, in Los Angeles, USA.

  • In cooperation with SURAGUS GmbH, the Fraunhofer Institute for Organic Electronics, Electron Beam and Plasma Technology FEP has succeeded in realizing non-contact in-situ measurements under high vacuum conditions at temperatures of up to 220°C within the HotSense project (grant number 100547507/4102) funded by the Saxon State Ministry of Economics, Labor and Transport (SMWA). Thus, measurements of the sheet resistance or -conductivity, or the metal layer thickness can be carried out in close proximity to the process directly after hot layer deposition or layer modification processes by means of non-contact high-frequency eddy current measurement. Furthermore, the developed setup can be adopted for process characterization up to 450 to 600 degrees Celsius. The results will be presented in a poster at SVC Techcon, May 8 – 11, 2023, in Washington D.C, USA.

  • The Fraunhofer Institute for Organic Electronics, Electron Beam and Plasma Technology FEP is intensively working on low-energy electron beam processes in aqueous biosystems in the field of medical and biotechnological applications. The scientists have shown that low-energy accelerated electrons can both inactivate and stimulate microorganisms aqueous environments in a dose-dependent manner. The dose is an important process variable and a measure of the effects caused by accelerated electrons in the liquid, which is quantified by dosimeters. The Fraunhofer FEP is developing radiochromic liquid dosimeters for different dose ranges in order to be able to determine the absorbed dose in a liquid during electron beam processes for biotechnological fields of applications. These will be presented at Medtec LIVE with T4M, May 23-25, 2023, in Nuremberg, at the Fraunhofer FEP booth, no. 1-558.

  • Lightweight, switchable and smart glass technologies can significantly improve the energy management of buildings with large-area windows and glass facades and contribute significantly to reducing energy consumption for heating or cooling. Improving the availability and cost efficiency of such smart glasses and the corresponding manufacturing processes is the declared goal of the EU-funded Switch2Save joint project. The project partners are now on the finish line and have installed the first electrochromic insulating glass units to demonstrate and test the potential energy savings in a Swedish office building. These and other smart solutions for windows and building facades will be presented at the BAU trade fair, April 17-22, 2022, in Munich/Germany, at the Fraunhofer joint booth 528 in hall C2.

  • Lithium-ion batteries (LIB) are indispensable key components for electro mobility and the success of the energy transition. They offer high energy density and high cycle stability. Eight partners from industry and science are developing technologies and components in the funded project "revoLect" (funding reference: 03ETE041) in order to be able to produce resource-saving and more efficient LIBs. The project is pursuing two key innovations: the replacement of the usual metal foils with a metallized fabric structure and the use of silicon as anode material.

  • Controlling light and heat radiation through windows and glass facades at the push of a button, saving energy and still maintaining a clear view? Switchable electrochromic films that turn dark but remain transparent are expected to make this possible in the future. The fact that this can also be retrofitted in existing buildings is to be demonstrated by the joint project "EnOB: FLEX-G 4.0 - Technologies for innovative switchable films as a retrofit solution for energy-saving windows and glass facades" (funding reference: 03EN1048), which is funded by the German Federal Ministry of Economic Affairs and Climate Action BMWK. Coordinated by the Fraunhofer Institute for Organic Electronics, Electron Beam and Plasma Technology FEP, the project will work with six other partners to advance the state of the art to the prototype stage over the next four years. In doing so, the project aims to kill two birds with one stone - on the one hand, the windows of a Dresden school are to be retrofitted, and on the other, the pupils are to be actively involved in the technology development as a contribution to promoting career orientation.

  • OLED microdisplays researched and developed at the Dresden Fraunhofer Institute for Organic Electronics, Electron Beam and Plasma Technology FEP have already been offered for several years as evaluation kits for potential exploitation partners. In addition to the design of application- and customer-specific microdisplay chips made possible by means of integrated circuit design, the industry-compatible, standardized manufacturing process technology development up to testing and characterization methods plays an important role. For the latter, a 64-device microdisplay test unit for characterization upon delivery or/and receipt of goods by customers will now be presented for the first time at embedded world 2023, at the Fraunhofer joint booth (Hall 4, No. 422).

  • Cleaning glass facades and solar installations is expensive and time-consuming. Dirt reduces the yield of solar modules. Reasons enough to research surfaces that minimize this effort. The Fraunhofer Institute for Organic Electronics, Electron Beam and Plasma Technology FEP has now succeeded within the European Union-funded NewSkin project (GA: 862100) in applying crystalline titanium oxide to ultra-thin glass using a roll-to-roll process, thus achieving hydrophobic surfaces that become superhydrophilic under UV light. Initial results of this showcase of some of the NewSkin open access upscaling facilities will be presented at the Fraunhofer joint booth, No. C2-528, during BAU 2023, April 17 – 22, in Munich, Germany.

    Glass facades characterize modern architecture. While solar radiation serves to support heating in winter, the building interior heats up in summer and requires active cooling. Smart windows can regulate the solar radiation according to the weather situation – a forward-looking solution in times of energy saving. Fraunhofer FEP has now succeeded in producing the world's first thermochromic layer on ultra-thin glass in a roll-to-roll process. These results will make mechanical blinds superfluous in the future and at the same time reduce the cooling and heating energy requirements of a building.

    Within the joint project LAOLA (funding code: 03INT509AF), which was funded by the German Federal Ministry of Education and Research (BMBF) and has now been completed, large-area lighting applications with organic light-emitting diodes (OLEDs) on flexible substrates should be developed. The project focused on ultra-thin glass, which offers advantages compared to plastic as a substrate due to its excellent barrier properties. At the Fraunhofer Institute for Organic Electronics, Electron Beam and Plasma Technology FEP, the OLEDs were applied to the flexible glass using a roll-to-roll process. A surgical light designed using this process will be presented at LOPEC 2022, on March 23 and 24, 2022, in Munich, at the joint booth of the project coordinator Organic Electronics Saxony e.V. (OES), No. B0.308.
