Abstract:

Triplet exciton dissociation in singlet exciton fission devices with three classes of acceptors are characterized: fullerenes, perylene diimides, and
PbS and PbSe colloidal nanocrystals. Using photocurrent spectroscopy and a
magnetic field probe it is found that colloidal PbSe nanocrystals are the
most promising acceptors, capable of efficient triplet exciton
dissociation and long wavelength absorption.
