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 three main branches: Organic light-emitting electrochemical cells, organic transistors and organic photovoltaics.

September 2013

The OPEG member Andreas Sandström has successfully defended his PhD thesis "Design and Fabrication of Light-Emitting Electrochemical Cells".

The thesis presents his work that has taken the small, laboratory scale LECs to impressive, large scale devices, including flexible devices fabricated by roll-to-roll techniques in ambient conditions.

July 2013

In the article "Photochemical Transformation of Fullerenes", we challenge the conventional picture of what happens when PCBM-fullerenes undergo light-induced dimerization. We propose a different reaction model and demonstrate its validity through analytical reasoning and computational modeling.

The work was published as cover feature article, in the scientific journal Advanced Functional Materials (Issue 25, pages 3220-3225, July 5, 2013).
