The main work lines of the team consist on the application of nanostructured and bio materials for the development of solar cells (including perovskite, quantum-dot, tandem, etc.), devices for water decontamination with visible light, bio-sensors and microbial fuel cells. We combine electrical and optical measurements, particularly impedance spectroscopy, with theoretical models and novel concepts to understand the operational mechanism of these devices and uncover the main performance limitations of these devices.

Short Biography of Dr. Fabregat

Francisco Fabregat Santiago (B.Sc. in Physics at Universitat de Valencia and University of Leeds in 1995 , Ph.D. from Universitat Jaume I in 2001). He joined Universitat Jaume I in 1998 where he is currently Associate Professor at Physics Department since 2010 and active member Institute of Advanced Materials (INAM). Among others he made several research stays at Uppsala University, Imperial College, École Polytechnique Fédérale de Lausanne. He authored 100 peer reviewed papers and book chapters, that accumulate more than 8500 cites with an h-index of 43. Dr. Faregat-Santiago is an expert in electro-optical characterization of devices and particularly known by his works in the use of the impedance spectroscopy to model, analyze and interpret the electrical characteristics (charge accumulation, transfer reactions and transport) of films and devices including ZnO and TiO2 nanostructured films (nanocolloids, nanorods and nanotubes), dye sensitized solar cells, electrochromic materials and liquid and solid state hole conductors. His current interests are focused in the in the analysis of the fundamental properties of nano and bio materials for their application in solar cells, photoinduced water decontamination, bio-energy and sensors.
