In 2012 the EU launched the TREASORES project (Transparent Electrodes for Large Area Large Scale Production of Organic Optoelectronic Devices) that aimed to develop technologies that will lower the production costs of organic electronic devices.
The Fraunhofer FEP now reports that the project concluded successfully and one of the results was the development of several new transparent electrode and barrier materials. The project partners developed electrodes based on carbon nanotubes, metal fibres or thin silver - and these electrodes (some of which are already mass produced) enabled the creation of the OLED lighting device you can see above.
That OLED was made in a roll-to-roll process at the Fraunhofer FEP's facilities, and achieved performance (25 lm/W efficiency, mostly) comparable to the performance of OLEDs produced at a conventional sheet-to-sheet process).
TREASORES was funded by the EU commission (€9 million) and the project partners (€6 million). The partner consortium includes the Fraunhofer FEP, OSRAM, Canatu and the NPL and was coordinated by the Empa institute in Switzerland.
