Dr. Gregoriou is the Director and Chairman of the Board at the National Hellenic Research Foundation (NHRF), one of the largest Research Centers in Greece. Dr. Gregoriou is an internationally known scientist with research and managerial positions in both Greece (NHRF, FORTH-ICEHT) and the US (Advent Technologies, Northeastern, MIT, Polaroid, Princeton). He holds a Ph.D. in Physical Chemistry from Duke University USA (1993), was a National Institutes of Health Research fellow (NIH NRSA award) at Princeton University (1994) and has attended the MBA program at Northeastern University in Boston MA (1998). His research activity extends over a wide area of subjects that include the areas of flexible photovoltaics based on organic semiconductors, optically active materials based on conjugated oligomers and polymer nanocomposites. He is the coauthor of 3 books, 6 chapters in books, 66 refereed research papers, 131 research presentations and the co-inventor of 5 patents. He has also cofounded Advent Technologies (www.advent-energy.com). He has also served as the President of the Society for Applied Spectroscopy (SAS) in 2001. Dr. Gregoriou is the Greek National Representative in the Horizon 2020 Committee for the European Research Council (ERC), the Mari Sklodowska-Curie actions, and the Future and Emerging Technologies (FET) (2014-).
The establishment of high-tech products relying on organic semiconductors demonstrates the remarkable technological maturity and competitiveness of these materials. In this presentation the latest strategies for improving the performance of conducting molecular systems and polymers that make them attractive for an ever-growing range of technological applications will be shown and discussed. In particular, the design of novel organic molecular materials as alternatives to fullerene derivatives and conjugated polymers with appropriate frontier orbital energy levels will be presented as well as low band gap (LBG) copolymers absorbing in the near infrared (NIR) region for use in various optoelectronic applications such as organic light emitting diodes (OLEDs), organic photovoltaics (OPVs) and organic photodetectors (OPDs).
