Pablo P. Boix works at the Institute of Materials Science (ICMUV), University of Valencia, Valencia, Spain. His profile combines basic education in Physics (bachelor by Universitat de València, 2008) and Nanoscience (Ph.D. by Universitat Jaume I, 2012; Master by Universitat Jaume I, 2010) with an extensive international experience developing optoelectronic devices and electrochemical characterization techniques, in both academic and industrial environments. His research interests include developing innovative materials and device configurations for optoelectronic applications, as well as unveiling their working mechanisms. He joined Nanyang Technological University (NTU, Singapore, 2012-2016) as a postdoctoral research fellow and became a group leader in perovskite optoelectronics at their early stage of the field. He contributed to pioneer advances in materials, such as the first formamidinium- based perovskite absorber and device concepts. After one year of industrial experience (Dyesol Ltd., Lausanne, Switzerland), he joined Universitat de València in 2017 with a Ramon y Cajal Fellowship. He has published more than 100 articles in peer-reviewed scientific journals (with h-index: 52) and 2 patents. He was able to participate as a "Young Scientist” at GYSS (Global Young Scientists Summit, January 2015, Singapore) and selected as Highly Cited Researcher in 2020 (Cross-Field).

Guichuan Xing is currently an Associate Professor at the Institute of Applied Physics and Materials Engineering, University of Macau, Macau, China. Dr. Xing's primary research interest is focused on developing and applying ultrafast nonlinear spectroscopic techniques to probing, understanding and controlling the fundamental charge and energy carrier generation, transport and relaxation in novel optoelectronic systems for energy conversion/storage and light emission applications. He has published more than 200 articles in peer-reviewed scientific journals.
