Athanassios G. Kontos studied Physics at the University of Athens. From 1990 to 1994, he carried out his Ph.D. research work in the Physics department at the University of Warwick (Coventry, UK) on the NMR study of high-Tc superconductors. From 1996 to 2007, he joined the Raman spectroscopy group in the School of Applied Mathematical and Physical Sciences at the National Technical University of Athens. During this period, he collaborated with the Institutes of Material Science and Microelectronics at NCSR ‘D’ and he presented rich teaching activity. He is an Associate Professor for the National Technical University of Athens. His main fields of research are dye sensitized solar cells (DSCs), the photocatalysis and superhydrophilicity of TiO2 materials, as well as CO2 capture and conversion. His interests include the synthesis of TiO2 in several forms (nanoparticles and nanotubes), its sensitization (dyes and quantum dots) and modification (anion doping, functionalization with metals and carbonaceous materials), as well as the structural (Raman spectroscopy), optical (UV-visible diffuse reflectance), and morphological (SEM and AFM) characterization of semiconducting nanomaterials, thin films, zeolitic imidazolate frameworks, and DSC devices. His research on DSCs emphasizes the optimization of their efficiency and stability.
