Xavier Crispin graduated from the University of Mons-Hainaut in 1995, in Chemistry. From 1995 to 2000 he was graduate student of Prof. J.L. Brédas in the Laboratory of the Chemistry of New Materials and Research Center in Molecular Electronics and Photonics. His research dealt with quantum chemical models to describe the (opto)electronic properties of conjugated molecules and the interaction between organic molecules and metals. In 2000, he received an individual Marcie-Curie Fellowship and spent two years as postdoctoral fellow at Linköping Universitet with Prof. W.R. Salaneck. In the Laboratory of Surface Physics and Chemistry, he has been trained to become a spectroscopist using various techniques (XPS, ARUPS, NEXAFS) to characterize the electronic structure of semi(conducting) polymers and molecules, the way they order and the energetics at interfaces with electrodes. In collaboration with Agfa-Geveart, he rationalized the secondary doping effect in the conducting polymers PEDOT-PSS, which leads to a significant increase of conductivity. PEDOT-PSS could then reach applications such as transparent electrodes in light emitting diodes and solar cells; as well as antistatic coating, electrochromic displays. In 2004, he became Associate Professor in the group of Prof. M. Berggren in Norrköping Campus, Linköping University. He worked on various electronics devices with a focus on low-voltage organic field effect transistors (OFETs). Xavier is a member of the Printed Electronics Arena and has actively taken part in the development of various prototypes nowadays products of spin-off companies. In 2011, Xavier was awarded the Tage Erlander’s prize from the Swedish Royal Academy of Science for his demonstration that conducting polymers can be thermoelectric materials. He is a grantee of the European Research Council under the ERC-starting grant program. In 2014, he became a Professor in the laboratory of Organic Electronics. Today, his research interest is focused on the use of conducting polymers in transistors and as energy materials in supercapacitors/batteries and thermoelectric devices.
