Eva M. Herzig is a professor at the Institute of Physics of the University of Bayreuth. She received her PhD from the Uni- versity of Edinburgh (UK) and worked in industry on renewable energies and as a postdoc at the Technical University of Mu- nich (Germany). Her group fo- cuses on nanostructure control via processing and the character- ization of thin films, applying time-resolved, multi-modal mea- surement methods to resolve structures on the nanoscale with a current focus on organic and hybrid energy materials. Feng Gao is a professor and Wal- lenberg Scholar at Linko<spacing diaeresis>ping Uni- versity in Sweden. He received his PhD from the University of Cam- bridge (UK) in 2011, followed by a Marie Sk & lstrok;odowska-Curie postdoc fellowship at Linko<spacing diaeresis>ping University. His group currently fo- cuses on research into solution- processed energy materials and devices, mainly based on organic semiconductors and metal halide perovskites. Jonas Bergqvist is CTO at Epis- hine AB. He holds a master's de- gree in applied physics and a doctoral degree in biomolecular and organic electronics from Linko<spacing diaeresis>ping University, Sweden. Jonas has 15 years of experience within organic solar cells and is one of the cofounders of Epishine AB, where he leads the technology development of roll- to-roll manufacturing of printed organic solar cells for indoor ap- plications. Maria A. Loi is a professor at the Zernike Institute for Advanced Materials of the University of Gro- ningen in the Netherlands. She received a PhD in physics from the University of Cagliari, Italy, in 2001. She has been a postdoc- toral fellow at the Johannes Kep- ler University in Linz, Austria, and at the National Research Council in Bologna, Italy. She joined the University of Groningen in 2006 as a Rosalind Franklin Fellow, and she became full professor in the same institution in 2014. She focuses on the investigation of the photophysics of unconven- tional semiconductors and in their application into optoelectronic devices. Sebastian B. Meier is the director of OPV technology and manufacturing at ASCA GmbH & Co. KG. He holds a diploma de- gree in materials science and a doctoral degree in engineering from the Friedrich-Alexander Uni- versity of Erlangen-Nuremberg, Germany. He has 15 years of in- dustrial experience in the field of organic and printed electronics and is author and co-author of numerous scientific publications in international nals as well as patents in the field of organic light-emitting devices and solar cells.
