That is made possible by singlet fission, a photophysical process in molecules and molecular aggregates whereby a singlet exciton generated by irradiation splits into two triplet excitons.

A current flows in a semiconductor when excitons—a combination of an electron and a positive hole—are split into these ...

We have been studying so-called indirect excitons. For a direct exciton in a quantum well (QW), both an electron and a hole are confined in the same QW. For an indirect exciton, however ...

Organic infrared (IR) photodetectors face significant challenges in achieving high external quantum efficiencies (EQE) due to inadequate dissociation of Frenkel excitons and pronounced non-radiative ...
