Perovskite-based tandem solar cells have emerged as one of the most promising technologies for next-generation photovoltaics. Reported efficiencies for some representatives already surpass the Detailed Balance Limit for single junctions. This symposium aims to provide a platform that brings together the perspective of cutting edge fundamental research with visionaries from industry R&D to discuss the 1 , 2 and potentially 3 generation of perovskite tandem solar technology. As such, the symposium targets tandem technologies that combine perovskite with established solar technologies (e.g. silicon), as well as tandem concepts that are solely based on emerging technologies (all-perovskite, perovskite-organic, ...). A dedicated focus will also be on light management as well as challenges and prospects of 4-terminal tandem concepts. Further, the process of tandem solar cell commercialization will be addressed. Besides scaling up to larger areas, device stability is key for terawatt scale application. We hence will focus on issues that are intimately linked with the concept of tandem solar cell technology (challenges of wide and low-gap solar cells, impact of the interconnect, …). Finally, we want to open the floor to confer about the next step for perovskite-based multi-junction solar cell technologies starting with triple[1]junctions to entirely new concepts.

Christiane BeckerDr. Fan Fu is a group leader at Empa-Swiss Federal Laboratories for Materials Science and Technology. He received his bachelor's and master's degrees in materials science from the Wuhan University of Technology in 2010 and 2013, respectively. He joined Prof. Ayodhya N. Tiwari's group as a Ph.D. student in 2014 and earned his Ph.D. degree from ETH Zürich with distinction in 2017. His doctoral thesis on perovskite-CIGS thin-film tandem solar cells was awarded ETH Medal. From January 2018 to May 2019, he worked as a postdoc researcher in Prof. Christophe Ballif's group at EPFL. In June 2019, he joined Empa as a group leader. He is currently leading a research team investigating novel perovskite semiconductors for energy and optoelectronics applications. In particular, his group's recent research efforts focus on upscaling high-performance perovskite-based tandem solar cells and mini-modules on flexible substrates.
René Janssen is university professor at the Eindhoven University of Technology (TU/e). He received his Ph.D. in 1987 from the TU/e for a thesis on electron spin resonance and quantum chemical calculations of organic radicals in single crystals. He was lecturer at the TU/e since 1984, and a senior lecturer in physical organic chemistry since 1991. In 1993 and 1994 he joined the group of Professor Alan J. Heeger (Nobel laureate in 2000) at the University of California Santa Barbara as associate researcher to work on the photophysical properties of conjugated polymers. Presently the research of his group focuses on functional conjugated molecules and macromolecules as well as hybrid semiconductor materials that may find application in advanced technological applications. The synthesis of new materials is combined with time-resolved optical spectroscopy, electrochemistry, morphological characterization and the preparation of prototype devices to accomplish these goals. René Janssen has co-authored more than 600 scientific papers. He is co-recipient of the René Descartes Prize from the European Commission for outstanding collaborative research, and received the Research Prize of The Royal Institute of Engineers and in The Netherlands for his work. In 2015 René Janssen was awarded with the Spinoza Prize of The Dutch Research Council.
