A completely roll-to-roll compatible light emitting device has been fabricated completely in air for the very first time! Using an ink developed in our group, and the roll coating expertise of our colleagues Henrik F. Dam and Frederik C. Krebs at the Technical University of Denmark, we managed to fabricate flexible and transparent light emitting foils using methods akin to how newspapers are made. This work was featured in the prestigious journal Nature Communications.

Knut and Alice Wallenberg foundation has awarded 40,5 MSEK to a research constellation including representatives from the Organic Photonics and Electronics Group. The goal of the research is to develop a sustainable green energy source, conceptualized as “an artificial leaf”.

Our work on "Direct UV-Patterning of Electronically Active Fullerene Films" was recently published as cover feature article in the scientific journal Advanced Functional Materials (Issue 19, pages 3723-3728, October 7, 2011).
The article describes how UV light is utilized for the attainment of high-resolution and electronically active patterns in [6,6]-phenyl C61-butyric acid methyl ester (PCBM) films with a novel, photoresist-free method.
Tougher demands on lighting design emphasise the importance of new illumination techiques. This story on Swedish national television uses our reserch on low-energy consuming light-emitting devices to exemplify novel ligthing technologies.
