In the singlet exciton fission process, a singlet exciton (blue) is created upon absorbing light and then splits into two triplets (red) on ultrafast timescales. The team tracked the real-time molecular motions acompanying this process in single crystals of pentacene. Credit: © Jörg Harms, MPSD
Researchers from the Fritz Haber Institute (FHI) in Berlin, the MPSD and the Julius-Maximilians-Universität Würzburg have provided important new insights into a key process for the development of more efficient solar cells and other light-based technologies, called singlet exciton fission. They have managed to track how molecules of a promising material, single crystals …
