James Durrant is Professor of Photochemistry in the Department of Chemistry, Imperial College London and Ser Cymru Solar Professor, University of Swansea. His research addresses the photochemistry of new materials for solar energy conversion targeting both solar cells (photovoltaics) and solar to fuel (i.e.: artificial photosynthesis. It is based around employing transient optical and optoelectronic techniques to address materials function, and thereby elucidate design principles which enable technological development. His group is currently addressing the development and functional characterisation of organic and perovskite solar cells and photoelectrodes for solar fuel generation. More widely, he leads Imperial's Centre for Processable Electronics, founded the UK�s Solar Fuels Network and led the Welsh government funded S�r Cymru Solar initiative. He has published over 500 research papers and 5 patents, and was recently elected a Fellow of the Royal Society

Sixto Giménez (M. Sc. Physics 1996, Ph. D. Physics 2002) is Associate Professor at Universitat Jaume I de Castelló (Spain). His professional career has been focused on the study of micro and nanostructured materials for different applications spanning from structural components to optoelectronic devices. During his PhD thesis at the University of Navarra, he studied the relationship between processing of metallic and ceramic powders, their sintering behavior and mechanical properties. He took a Post-Doc position at the Katholiek Universiteit Leuven where he focused on the development of non-destructive and in-situ characterization techniques of the sintering behavior of metallic porous materials.  In January 2008, he joined the Group of Photovoltaic and Optoelectronic Devices of University Jaume I where he is involved in the development of new concepts for photovoltaic and photoelectrochemical devices based on nanoscaled materials, particularly studying the optoelectronic and electrochemical responses of the devices by electrical impedance spectroscopy. He has co-authored more than 80 scientific papers in international journals and has received more than 5000 citations. His current h-index is 31. 

Professor Adélio Mendes (born 1964) received his PhD degree from the University of Porto in 1993.

Full Professor at the Department of Chemical Engineering of the Faculty of Engineering of the University of Porto. Coordinates a large research team with research interests mainly in dye sensitized solar cells and perovskite solar cells, photoelectrochemical cells including water splitting and solar redox flow batteries, photocatalysis, redox flow batteries, electrochemical membrane reactors (PEMFC, H-SOFC, chemical synthesis), methanol steam reforming, membrane and adsorbent-based gas separations and carbon molecular sieve membranes synthesis and characterization.

Professor Mendes authored or co-authored more than 300 articles in peer-review international journals, filled 23 families of patents and is the author of a textbook; received an Advanced Research Grant from the ERC on dye-sensitized solar cells for building integrated of ca. 2 MEuros and since 2013 he is partner in 4 more EU projects and leads one EU project. Presently he is the leader of a FET Open project, GOTSolar, on perovskite solar cells. He received the Air Products Faculty Excellence 2011 Award (USA) for developments in gas separation and Solvay & Hovione Innovation Challenge 2011 prize, the Prize of Coimbra University of 2016, and the prize of Technology Innovation - 2017 by the University of Porto. Presently, he is the Coordinator of CEner-FEUP, the Competence Center for Energy of the Faculty of Engineering at the University of Porto.

Ifan is a Professor in Electrochemistry at the Department of Materials at Imperial College: he leads the Interfacial Electrochemistry Group there and is also Atoms to Devices Research Area Lead at the Henry Royce Institute.

Ifan joined Imperial College in July 2017. Prior to Imperial, he was at the Department of Physics at the Technical University of Denmark (DTU); he was first employed as a postdoctoral researcher, then  as assistant professor and finally as associate professor and leader of the Electrocatalysis Group there. In 2015, Massachusetts Institute of Technology (MIT) appointed Ifan as the Peabody Visiting Associate Professor. He taught and conducted research at the Department of Mechanical Engineering at MIT for a whole semester.

Ifan’s research aims to enable the large-scale electrochemical conversion of renewable energy to fuels and valuable chemicals and vice versa. Such processes will be critical in order to allow the increased uptake of renewable energy. His focus is on the catalyst at the electrode, i.e. the electrocatalyst. It turns out that the electrocatalyst material defines the efficiency of several important electrochemical processes, including:(i) electrolysis for the storage of renewable electricity — which is inherently intermittent — in the form of fuels, such as hydrogen or alcohols.(ii) fuel cells as a potentially zero emission source of power for automotive vehicles. (iii) the green synthesis of valuable chemicals, such as ammonia and H2O2. (iv) batteries, which tend to degrade by gas evolution at the electrode-electrolyte interface. Hence the reactions that need to be accelerated in electrolysers and fuel cells — such as CO2, CO, O2 and H2 evolution — are precisely those that need to be inhibited in batteries.

Ifan has discovered or co-discovered several new catalysts for the oxygen reduction reaction, which exhibited significant improvements in performance over the prior state-of-the-art. In particular, his research on hydrogen peroxide production led to the establishment of the spinout company, HP Now.

Ifan is the recipient of RSC's Geoffrey Barker Medal (2024), the RSC's John Jeyes Award (2021). He also currently holds an European Resarch Council Consolidator Grant (2021-2025). Since 2022, he has been a Clarivate Highly Cited Researcher.
