The Role of FRET in Non-Fullerene Organic Solar Cells: Implications for Molecular Design
JOURNAL OF PHYSICAL CHEMISTRY A, 122(15), 3764–3771.
TL;DR:
It is shown that when charge transfer and exciton transfer processes are both present, the coexistence of excites in both domains can cause a loss mechanism and excitons in low-bandgap material should have a relatively long lifetime compared to the transfer time of exciton population in the larger bandgap acceptor domains.
