The third edition of the International Conference on Organic Electronics (ICOE) was held at the High-Tech Campus in Eindhoven, The Netherlands, June 04-07 2007

ICOE arised as an initiative of the European Framework 6 IST Programme through the Integrated Project 'PolyApply'. This conference addresses all issues related to organic electronics, such as materials, manufacture, Organic Thin Film Transistors (OTFTs), OLEDs, PV devices, organic circuit design, and organic device modeling.

Many interesting papers were presented, mostly from Europe. It should be mentioned that there are many European teams currently working on organic electronics.

There were not many paper dealing with device modeling, although there were interesting. We can highlit the papers entitled "Modeling Traps in ultrathin pentacene transistors," by A. D. Geiser, A. von Mühlenen, N. Errien and L. Zuppiroli (EPFL, Lausanne, Switzerland), "Paper Charge Injection Model for Organic Light-emitting Diodes," by L. Li, G. Meller, and H. Kosina (Institute for Microelectronics, TU-Wien, Wien, Austria).

One paper presented a compact model for OTFTs, assuming a transport mechanism based on a quasi-drift-quasi-diffusion theory.. It was entitled "Analytical modelling of TFTs and diodes on small molecule organic semiconductor devices," by S. Prior, D.Donaghy, W.Eccleston (Organic Electronics Group, University of Liverpool, Liverpool, UK), and B. Stablober and A. Haase (Joanneum Research, Austria).

The invited speakers were also top scientists in Organic Electronics. Sergei Baranovski (Philipps-University Marburg, Germany) presented a theory of the charge transport in disordered organic materials. Dan Frisbie (University of Minnesota, USA) made a talk about the Polymer Electrolyte-Gated Organic Field-Effect Transistors. Hagen Klauk (Max Planck Institute for Solid State Research, Stuttgart, Germany) made a very interesting presentation about low voltage organic transistors and circuits. Takao Someya (University of Tokyo, Japan) addressed the printed organic transistors for large-area skin-like sensors and actuators.

Despite PolyApply will end at the end of 2007, it is expected that ICOE will still be held new year, supported by other sponsors.
