Many thanks to our undergraduates, graduate students, staff, and group leaders for their fantastic accomplishments in 2021. Together we have successfully managed the second Coronayear! I would like to thank everyone who worked tirelessly and meticulously to ensure rigorous implementation of Coro... Continue

Difei already left i-MEET after more than a year working in our group on novel Y6 derivatives and is continuing her career back at SCUT. Yakun is leaving i-MEET after 5 years PhD and ~ 1 year Postdoc working on double cable materials and will join KAUST as a Postdoc working on the photophysics of a... Continue

Chao passed her PhD examination with the great success and excellent grades! Her study focused on the development of advanced functional interface materials as required for the scalable production of highly efficient and stable organic solar cells with simple solution processing techniques. One maj... Continue

Our beautiful and very successful cooperation with Weiwei from Beijing University of Chemical Technology on double conjugated polymers delivering 10 % for the first time. From 1998 - 2000, the first European Project on organic solar cells (Molecular Plastic Solar Cells) concluded that double cable ... Continue

Solvent vapor annealing (SVA) has established itself as a highly efficient post-treatment process for enhancing power conversion efficiency (PCE). In cooperation with the Prof Spiecker group and CENEM we investigate the mechanisms of the SVA process of Organic Bulk-Heterojunction Blends. Thanks to ... Continue

Solar cells transparent in the visible range are highly requested for integration in see-through photovoltaic (PV) applications such as building glass façades or greenhouse roofs. The development of advanced transparent PV can fully exploit the tandem technology where the top cell absorbs the near-... Continue

Stability is one of the most important challenges facing material research for organic solar cells on their path to further commercialization. Our recent article in Nature Communications focuses on degradation mechanisms of inverted photovoltaic devices in the high-performance material system PM6:Y... Continue
