报告内容摘要：

Organic solar cells have the potential to revolutionise the way we harness the power of the sun. They are based on earth-abundant non-toxic raw materials and can be processed by inexpensive and scalable production technologies like roll-to-roll printing or vacuum processes on flexible substrates and on large areas. However, organic solar cells are still significantly less efficient compared to their inorganic counterparts. While organic molecules can absorb light much better than silicon, charge carrier extraction as well as energy losses at open circuit seem to limit the power conversion efficiency of organic solar cells. Over the past years, a particular focus has been put on a better understanding of the latter, highlighting the role of the charge transfer states in the generation and recombination of charge carriers as well as limiting the open circuit voltage, which will be the focus of this presentation.

Prof. Moritz Riede is associate professor for Soft Functional Nanomaterials at the University of Oxford, UK. Before joining Oxford, he was postdoc and led a junior research group on organic solar cells at the Institut für Angewandte Photophysik of the Technical University of Dresden, Germany. He has published more than 120 research articles, four book-chapters as co-author, one book as co-editor and one special journal issue as guest editor. He hold several patents and received the Academics “Junior Researcher of the Year 2011” award in Germany and was elected into the Global Young Academy in 2014, for which he served as co-chair from 2017 to 2018. His interests are organic solar cells, the transition of our energy system to renewable energy and the role of science in society.
