Juan Bisquert

Juan Bisquert is a Distinguished Researcher at Instituto de Tecnología Química (Universitat Politècnica de València-Consejo Superior de Investigaciones Científicas). He was professor of Applied Physics at Universitat Jaume I de Castelló from 2004 to 2024. He has been the funding director of the Institute of Advanced Materials (INAM). He published 400 papers in research journals, and authored a series of books, summarized in the volume Physics of Solar Energy Conversion (CRC Press 2020) that establishes a general physical picture of solar energy devices. He has 44000 citations and h-index 107 (Clariviate). He is Executive Editor for Europe of the Journal of Physical Chemistry Letters. He has been distinguished in the list of Highly Cited Researchers from 2014 to 2023 and the PLOS Biology standardized citation metrics, where he ranks n. 7 in Spain. He created and manages nanoGe Conferences. The research activity of Juan Bisquert has been focused on materials and devices for production and storage of clean energies, in particular photovoltaic devices, based on nanostructured metal oxides, semiconductor quantum dots, organic and hybrid semiconductors, and related applications such as luminescence. The main contribution of Bisquert by which he established an international reputation is the application of measurement techniques and physical modeling in several areas of energy devices, relating 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 device models, and the development of a general physical picture of solar energy devices. Halide perovskites are photovoltaic and optoelectronic semiconductor with easy preparation routes and excellent performance that have created a large international research community. These materials show excellent performance and radically new semiconductor properties. Unraveling the mechanisms and operational properties of perovskite solar cells has established scientific work of high impact by Bisquert and coworkers. Currently the main research topic aims to create miniature devices that operate as neurons and synapses for bio-inspired neuromorphic computation related to data sensing and image processing. The brain, a complex structure, integrates computing and memory through analogue signals transmitted among spiking neurons. Spiking Neural Networks (SNN) enable the development of neuromorphic computation systems that mimic biological brains. These systems excel at handling noisy data and stimuli, making them well-suited for perception, cognition, and motor tasks. The ERC-funded PeroSpiker project aims to develop miniature material elements that emulate the behaviour of neurons and synapses, resulting in smaller, simpler, and more energy-efficient SNNs. The project focuses on metal halide perovskite, an ideal material for creating devices that mimic biological membranes and synapses.
