Singlet Exciton Fission: Breakthrough for More Efficient Solar Cells and Light-Based Technologies (Reference : scitechdaily.com)
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 comprised of pentacene molecules, move in real time as singlet fission takes place, showing that a collective motion of molecules may be the origin of the fast timescales connected to this process.
Energy generation in light-based technologies relies on the ability of materials to convert light into electrical power and vice versa. Certain organic molecular solids have the peculiar ability to significantly increase the solar to electrical power conversion efficiency, thanks to a process called singlet exciton fission (SEF). In this process two electron hole pairs, which are called excitons, are generated by the absorption of one light quantum (a photon). Because of the pronounced technological implications, tremendous research efforts have been dedicated to understanding how SEF really works.
