Dr Johann Bouclé is currently an Associate Professor at the XLIM Research Institute (CNRS UMR 7252 / University of Limoges, France) and head of the Printed Electronics for Telecoms and Energy (ELITE) group, where he is developing a research axis devoted to hybrid optoelectronic devices based on organic and inorganic semiconductors, especially for energy conversion and light emission. He obtained a Ph.D. degree in Physics in 2004 on polymer/nanocrystal composites for nonlinear optics (University of Le Mans, France / CEA Saclay) and was then appointed as a postdoctoral research associate in the United Kingdom, initially at Imperial College London (with Prof Jenny Nelson) and then at the University of Cambridge (with Prof Neil Greenham), to develop novel hybrid solar cells based on polymers and metal oxide nanostructures. His activity has led him to coordinate several granted projects (CNRS, Regional, ANR, FEDER) involving many French and foreign institutions, and he is currently involved in the scientific boards of various French bodies in the fields of printed electronics, solar cells, and electrical energy. More recently, he has been focusing on interfaces and organic and hybrid devices for visible light communications.
