Feng Gao is a professor and Wallenberg Scholar at Linköping University in Sweden. He received his Ph.D. from the University of Cambridge in 2011. He received career grants and awards from the European Research Council, the Royal Swedish Academy of Sciences, the Wallenberg Foundation, and Swedish Foundation for Strategic Research. His group currently focuses on research into solution-processed energy materials and devices, mainly based on organic semiconductors and metal halide perovskites.

Dr. Yana Vaynzof is the Chair for Emerging Electronic Technologies at the Technical University of Dresden (Germany) and a Director at the Leibniz Institute for Solid State and Materials Research Dresden. She received a B.Sc. in Electrical Engineering from the Technion – Israel Institute of Technology (Israel) in 2006 and a M. Sc. In Electrical Engineering from Princeton University (USA) in 2008. In 2011, she received a Ph.D. in Physics from the University of Cambridge (UK). Yana was a postdoctoral research associate at the Cavendish Laboratory, University of Cambridge (UK) and an assistant professor at Heidelberg University (Germany) from 2014 to 2019. Yana Vaynzof is the recipient of a number of fellowships and awards, including the ERC Starting Grant, ERC Consolidator Grant, Gordon Wu Fellowship, Henry Kressel Fellowship, Fulbright-Cottrell Award and the Walter Kalkhof-Rose Memorial Prize. She is a Fellow of the Royal Society of Chemistry and the winner of the Energy & Environmental Science Lectureship Award. Her research interests lie in the field of emerging photovoltaics, focusing on the study of material and device physics of organic, quantum dot and perovskite solar cells by integrating device fabrication and characterisation with the application and development of advanced spectroscopic methods.

Kai Zhu is currently a senior scientist in the Chemistry and Nanoscience Center at the National Renewable Energy Laboratory (NREL). He received his PhD degree in physics from Syracuse University in 2003. Before this position, he worked as a postdoctoral researcher in the Basic Science Center at NREL, focusing on fundamental charge carrier conduction and recombination in photoelectrochemical cells, especially dye-sensitized solar cells. Dr. Zhu’s research on dye-sensitized solar cells involves the development of advanced electrode materials/architectures, basic understanding of charge transport and recombination processes in these electrodes, and thin-film solar cell development/characterization/modeling. His recent research has centered on both basic and applied research on perovskite solar cells, including perovskite material development, device fabrication and characterization, and basic understanding of charge carrier dynamics in these cells. In addition to solar conversion applications, his research interests have also included III-Nitride wide-bandgap semiconductors for high-power blue and UV light emitting diodes and ordered nanostructured electrodes for Li-ion batteries and supercapacitors.
