Juan Bisquert is a professor of applied physics at Universitat Jaume I de Castelló, Spain. He is the director of the Institute of Advanced Materials at UJI. He conducts experimental and theoretical research on nanoscale devices for production and storage of clean energies. His main topics of interest are materials and processes in perovskite solar cells, nanostructured solar cells, solar fuel production, and lithium battery. 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. He authored 300 peer reviewed papers, and a reference book, Nanostructured Energy Devices. His h-index 65, and is currently a Senior Editor of the Journal of Physical Chemistry, and member of Editorial Board of Energy and Environmental Science and ChemElectroChem. He has been distinguished in the 2014 list of ISI Highly Cited Researchers.
