报告摘要:

 

Singlet fission (SF), the spontaneous down-conversion of a singlet exciton into two triplet excitons residing on neighboring molecules, is a promising route to improving organic photovoltaic (OPV) device efficiencies by harvesting two charge carriers from one photon. However, only a few materials have been discovered that exhibit intermolecular SF in the solid state. We use many-body perturbation theory in the GW approximation and the Bethe-Salpeter equation (BSE) to investigate the excitonic properties and possibility of intermolecular SF in molecular crystals, which is important for understanding SF mechanism and finding SF candidates for practical application.
