Juan Bisquert is a professor of Applied Physics at Universitat Jaume I de Castelló. He is the director of the Institute of Advanced Materials. He is Executive Editor for Europe of the Journal of Physical Chemistry Letters. The research activity of Juan Bisquert has been focused on materials and devices for production and storage of clean energies, in particular photovoltaic devices. He published 400 papers in research journals and authored the volume The Physics of Solar Energy Conversion (CRC Press 2020). The research field is dominated by hybrid metal halide perovskites, a class of photovoltaic materials and devices that show excellent performance and radically new semiconductor properties. Due to mixed ionic-electronic properties it is possible to construct resistive switching for memory applications and brain-inspired computing.
