Fundamental mechanisms of perovskite photovoltaics and solar fuel devices.

The main work on the team is the investigation of fundamental mechanisms governing the operation of light to energy conversion in semiconductor materials and devices. The research program is about in perovskite solar cells, nanostructured solar cells (including dye-sensitized solar cells, organic solar cells, quantum-dot sensitized solar cells), and water splitting with visible light and semiconductors (solar fuel generation). We combine experimental investigation and theoretical and numerical tools to develop insights in the electronic processes in hybrid organic-inorganic solar cells, combining novel theory of semiconductor nanostructures, photoelectrochemistry, and systematic experimental demonstration. We apply a broad range of concepts and characterization methods to analyze the operation of photovoltaic and optoelectronic devices in general, in a highly interdisciplinary strategy. One important tool of analysis is the application of impedance spectroscopy and related frequency domain methods that enable us to separate different operation processes in working devices.

Short Biography of Prof. Bisquert

Juan Bisquert (M.Sc. degree in physics in 1985 and the Ph.D. degree in 1992, both from the Universitat de València, Spain) worked in the Universidad de Castilla-La Mancha, Albacete, from 1987 to 1992, and is a professor of applied physics at Universitat Jaume I de Castelló (2004). At UJI he is the director of the Institute of Advanced Materials, that develops research activity on materials, nanostructures and devices for production and efficient use of clean energies. He published 320 papers in research journals, and a reference book, Nanostructured Energy Devices. He has 14000 citations and h-index 71. He is a Senior Editor of the Journal of Physical Chemistry Letters and member of the editorial board of Energy and Environmental Science, ChemElectroChem and the South Korean Journal of Electrochemical Science and Technology. He has been distinguished in the 2014 and 2015 list of ISI Highly Cited Researchers. He cooperates with research project management with King Abdulaziz University and King Saud University of Saudi Arabia. He conducts experimental and theoretical research on materials and devices for production and storage of clean energies. His main topics of interest are materials and processes in perovskite solar cells and solar fuel production. He has developed the application of measurement techniques and physical modeling of nanostructured energy devices, that relate the device operation with the elementary steps that take place at the nanoscale dimension: charge transfer, carrier transport, chemical reaction, etc., especially in the field of impedance spectroscopy, as well as general device models.
