Christian Breyer is Professor for Solar Economy at LUT University, Finland. His major expertise is the integrated research of technological and economic characteristics of renewable energy systems specializing in energy system modeling for 100% renewable energy, on a local but also global scale. His team published the most studies on 100% renewable energy for countries or major regions globally. Energy system transition studies are carried out in full hourly and high geo-spatial resolution. Publications cover integrated sector analyses with power, heat, transport, desalination, industry and negative CO2 emission options. Carbon capture and utilisation as part of comprehensive Power-to-X investigations is a core research field for his team. He published more than 250 scientific papers, thereof more than 100 in scientific journals. He worked previously for Reiner Lemoine Institut, Berlin, and Q-Cells (now: Hanwha Q Cells). He is member of ETIP PV, IEA-PVPS, scientific committee of the EU PVSEC and IRES, scientific advisory board of CO2 Value Europe, chairman for renewable energy at the Energy Watch Group, reviewer for the IPCC and a co-founder of the Desertec Foundation. His academic background is general business, physics and energy systems engineering and a PhD in electrical engineering. He communicates in Twitter @ChristianOnRE.
Jörg Müller is Senior Vice President R&D Cells at Hanwha Q Cells GmbH, his responsibility include the development and optimization of cost effective, high efficiency silicon solar cells and their implementation in gigawatt scale production. He studied physics in Munich and Edinburgh. In 2000 he joined ISFH working in the field of rear contacted and bifacial sensitive solar cells. He received his Ph.D. degree from Hannover University in 2005. He joined Q-Cells SE in 2004 working in several positions in the technology division. Since 2007 he is leading the crystalline silicon cell development at Q Cells.
Jangwon Seo is Director at Department of Convergent Energy Materials and Group Leader of perovskite solar cell team at Korea Research Institute of Chemical Technology (KRICT) in Daejeon, South Korea. He received his B.S., M.S. and Ph.D. degree from Seoul National University in 1998, 2000 and 2006. He worked as postdoctoral researcher at University at Buffalo, the State University of New York, from 2007 to 2012. He joined KRICT in 2013. Then, he has been working as senior/principal scientist of perovskite solar cell team at KRICT. His past research experience includes study on synthesis of organic semiconducting materials, polymers, and inorganic nanomaterials for optoelectronic applications. His primary research interest is developing an efficient perovskite solar cells and modules with high stability. His group achieved world record efficiencies of 22.7%, 24.2% and 25.2% in perovskite solar cells in the past 4 years. His group has published several important papers on efficient and stable perovskite solar cells including Nature Energy (2018), Nature (2019) and Nature Communications (2020).
Ayodhya N. Tiwari is the head of the Laboratory for Thin Films and Photovoltaics, Empa-Swiss Federal Laboratories for Material Science and Technology, and a Professor at ETH (Swiss Federal Institute of technology) Zürich, Switzerland. He is the Chairman and founder of ETH-spinout company Flisom in Zurich to transfer the lab’s innovative research excellence in flexible lightweight solar cells to industrial manufacturing. He has been conferred with an honorary doctorate degree by the Hasselt University, Belgium for his contributions in the field of thin film solar cells.
Dr. Tiwari has more than 37 years of R&D experience in various thin film photovoltaic technologies. He is a co-author of more than 280 research publications and about 260 conference presentations including numerous invited papers and talks. He has co-chaired or co-organised several international conferences, co-edited special issues of leading journals on solar cells and thin films, is serving on the editorial boards of journals. He has been advisor to various institutions and expert delegation member of EU and other national agencies. Dr. Tiwari is a co-recipient of several awards and recognitions, his students have won young scientist and other awards (24 in total) at international conferences for innovative research in thin film solar cells.
Important contributions of Tiwari’s group include: development of highest record efficiency flexible solar cells : 20.4% efficiency CIGS and 13.8% efficiency CdTe solar cells on polymer films with processes suitable for roll-to-roll manufacturing; monolithic interconnected flexible solar mini-modules with 16.9% efficiency; simple and safe non-vacuum deposition processes for CIGS and Kesterite solar cells; development of highly efficient semi-transparent Perovskite solar cells and CIGS based multi-junction (tandem) solar cells – recently achieved 22.7% perovskite/CIGS tandem solar
