The Organic Photonics and Electronics Group
The Organic Photonics & Electronics Group designs, fabricates and develops photonic and electronic devices based on novel organic compounds, either synthesized in-house or acquired via collaborators. The group is lead by professor Ludvig Edman and the research is divided into two main branches, one focusing on organic light-emitting electrochemical cells and the other on patterning and organic transistors.
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.Ambient fabrication of flexible and large-area organic light-emitting devices using slot-die coatingThe technology journal Ny Teknik has also published a story on the same work, as did the regional news channel Västerbottensnytt.

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.
