Abstract

Triplet states are a key species that commonly form during the operation of organic electronic devices such as light emitting diodes and solar cells. Although traditionally seen as a loss mechanism in organic photovoltaics, the unique properties of triplets are increasingly being manipulated to enhance device efficiencies instead, through strategies such as singlet fission and up-conversion. Indeed, interest in triplet states has been mounting owing to their recently discovered prevalence in highly efficient non-fullerene acceptor blends. As such, it is important to elucidate triplet pathways in organic solar cells, in particular how they affect charge photogeneration and recombination. This talk will cover two blend systems with intriguing triplet / charge interactions.
