Organic electronics is a fascinating field of research and is seen as a key technology enabling the field of large area and flexible electronics. Several applications of organic electronics have already found their way to the end user or are close to commercialization. Organic light emitting diodes are currently used in the latest generation of mobile phones and large TV sets, organic solar cells have reached efficiencies beyond 10%, and organic transistors are being discussed as ion-to electron transducers capable of interfacing biological matter with organic semiconductors.

In this presentation I will present the status and challenges of organic electronics. In particular, I will discuss the basics of the organic doping technology [1,2] and how doping can be used to make organic transistors more reliable [3]. Special emphasis will be put on organic electrochemical transistors that are emerging as a new paradigm for the field of organic bio-electronics [4].

Björn Lüssem studied electrical engineering at the RWTH Aachen (Germany) and the University of Bath (GB) and obtained his degree as Diplom-Ingenieur in 2003. He prepared his PhD thesis at the Research Center in Jülich, Germany in the field of molecular electronics. His thesis concentrates on Scanning-Tunneling Microscopy of pure and mixed self-assembled monolayers and has been awarded the VDE-Promotionspreis and the Günther-Leibfried-Preis. After staying at the Materials Science Laboratory of Sony in Stuttgart (Germany) from 2006-2008, he joined Prof. Leo’s group at the TU Dresden, where he headed the OLED and the New Devices group. In 2014 he started as Assistant Professor at the Physics Department of Kent State University, where he is researching fundamental device physics and charge transport in organic semiconductors.
