Graphene and Semiconductors

Biography

Dr Johann Bouclé is currently Associate Professor at the XLIM Research Institute (CNRS UMR 7252 / University of Limoges, France), where he manages a research axis devoted to hybrid optoelectronic devices based on organic and inorganic semiconductors. He obtained a PhD degree in Physics in 2004 on polymer/nanocrystal composites for nonlinear optics (University of Le Mans, France / CEA Saclay) and was then appointed 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 led him to coordinate several granted projects (CNRS, Regional, ANR, FEDER) involving many French and foreign institutions in the field. Habilitated for research management (French HDR) since 2015, he is currently involved in the scientific boards of various French bodies in the field of printed electronics and solar cells. He is member of the International advisory board of the African Graphene Center, and currently contribute to the development of graphene-based interfacial materials for photovoltaic applications, and mainly perovskite solar cells. He has co-authored 43 international journal articles and peer-reviewed conference proceedings, 2 book chapters, 1 patent, and more than 85 communications during national and international conferences.

Research Interest

His current scientific activity focuses on the development and characterization of organic and hybrid optoelectronic devices. In particular, I particularly enjoy hybrid systems based on organic and inorganic semi-conductors, which take benefit from the physical properties of both components, as well as their associated interfaces and photo-physical and charge transfer processes. In this context, I demonstrate a significant track record in the field of solid-state dye-sensitized solar cells, organic bulk heterojunction, and polymer/carbon nanotubes composites. More recently at XLIM, I initiated several studies devoted to optoelectronic devices based on hybrid perovskite active layers, both for photovoltaic energy conversion and light emission. Regarding carbon nanostructures, I recently demonstrated efficient metal oxide / carbon nanotube composites for hybrid solar cells (both perovskite and dye-sensitized devices), and I am currently developping graphene-based materials for this application.
