Juan A. Anta is Full Professor of Physical Chemistry at the University Pablo de Olavide, Seville, Spain. He obtained a BA in Chemistry in the Universidad Complutense of Madrid (Spain) and carried out his PhD research at the Physical Chemistry Institut of the National Research Council of Spain. His research focuses on fundamental studies of energy photoconversion processes, especially on dye and perovskite solar cells, using numerical simulation and modelling tools, as well as advanced optoelectronic characterization techniques such as impedance spectroscopy and other small perturbation techniques.

Joseph M. Luther obtained B.S. degrees in Electrical and Computer Engineering from North Carolina State University in 2001. At NCSU he began his research career under the direction of Salah Bedair, who was the first to fabricate a tandem junction solar cell. Luther worked on growth and characterization high-efficiency III-V materials including GaN and GaAsN. His interest in photovoltaics sent him to the National Renewable Energy Laboratory (NREL) to pursue graduate work. He obtained a Masters of Science in Electrical Engineering from the University of Colorado while researching effects of defects in bulk semiconductors in NREL�s Measurements and Characterization Division. In 2005, He joined Art Nozik�s group at NREL and studied semiconductor nanocrystals for multiple exciton generation for which he was awarded a Ph.D. in Physics from Colorado School of Mines. As a postdoctoral fellow, he studied fundamental synthesis and novel properties of nanomaterials under the direction Paul Alivisatos at the University of California and Lawrence Berkeley National Laboratory. In 2009, he rejoined NREL as a senior research scientist. His research interests lie in the growth, electronic coupling and optical properties of colloidal nanocrystals and quantum dots.

Juan P. Martínez-Pastor, Full Prof. at the University of Valencia. PhD in Physics, 1990. Three years of postdoctoral experience at the European Laboratory of Non-Linear Spectroscopy (Florence, Italy) and at the École Normale Supérieure (Paris, France). Prof. Martínez-Pastor is expert in Semiconductor Physics, particularly optical properties and exciton recombination dynamics in quantum wells, wires and dots based on III-V semiconductors and other compounds since 1990. This research line continues nowadays focused on quantum light produced by quantum dot semiconductors and its management for quantum communications. After 2006 he has leaded/co-leaded several research lines in nanoscience and nanotechnology regarding the development of several types of nanomaterials (metal and quantum dots, multi-functional nanocomposites) and applications to photonics and plasmonics. In the last three years, he focuses his research in optical properties, exciton recombination dynamics and applications in photonics of two-dimensional semiconductors and metal halide perovskites. He has supervised 16 PhD theses and is author/co-author of 220 peer-reviewed publications, other than seven patents and promotor of a spin-off company.

Hernán Míguez (born in Buenos Aires, Argentina, 1971) is Research Professor of the Spanish Research Council (CSIC) in the Institute of Materials Science of Seville. He studied Physics in the Universidad Autónoma de Madrid and did his PhD in the Institute of Materials Science of Madrid. After a postdoctoral stay at the University of Toronto in the group of Prof. Ozin, he returned to Spain and joined the CSIC in 2004. He leads the group of Multifunctional Optical Materials, whose activities are devoted to the development, characterization and modeling of new photonic architectures for applications in different fields, among them solar energy conversion and light emission. He has received an ERC starting grant (2012, Consolidator Modality) and the “Real Sociedad Española de Física-Fundación BBVA 2017” Prize in the modality of “Physics, Innovation and Technology”.

Paulina Plochocka, Directrice de recherché de 2e classe (DR2) in Laboratoire National des Champs Magnétiques Intenses (LNCMI), CNRS in Toulouse.

P. Plochocka obtained her PhD cum-laude in 2004 at the University of Warsaw working on the dynamics of many-body interactions between carriers in doped semi-magnetic quantum wells (QW). During her first post doc at Weizmann Institute of science, she started working on the electronic properties of a high mobility 2D electron gas in the fractional and integer quantum Hall Effect regime. She continued this topic during second post doc in LNCMI Grenoble, where she was holding individual Marie Curie scholarship. At the same time, she enlarged her interest of 2D materials towards graphene and other layered materials as TMDCs or black phosphorus. In 2012 she obtained permanent position in LNCMI Toulouse, where she created the Quantum Electronics group, which investigates the electronic and optical properties of emerging materials under extreme conditions of high magnetic field and low temperatures. Examples include semiconducting layer materials such as transition metal dichalcogenides, GaAs/AlAs core shell nanowires and organic inorganic hybrid perovskites.

Sam Stranks is Professor of Optoelectronocs and Royal Society University Research Fellow in the Department of Chemical Engineering & Biotechnology and the Cavendish Laboratory, University of Cambridge. He obtained his DPhil (PhD) from the University of Oxford in 2012. From 2012-2014, he was a Junior Research Fellow at Worcester College Oxford and from 2014-2016 a Marie Curie Fellow at the Massachusetts Institute of Technology. He established his research group in 2017, with a focus on the optical and electronic properties of emerging semiconductors for low-cost electronics applications.

Sam received the 2016 IUPAP Young Scientist in Semiconductor Physics Prize, the 2017 Early Career Prize from the European Physical Society, the 2018 Henry Moseley Award and Medal from the Institute of Physics, the 2019 Marlow Award from the Royal Society of Chemistry, the 2021 IEEE Stuart Wenham Award and the 2021 Philip Leverhulme Prize in Physics. Sam is also a co-founder of Swift Solar, a startup developing lightweight perovskite PV panels, and an Associate Editor at Science Advances.
