Solar energy is an ample renewable energy resource, with photovoltaic (PV) technology
enabling a direct route from light to electricity. Currently, PVs are limited in photon …

The exciton, an excited electron–hole pair bound by Coulomb attraction, plays a key role in
photophysics of organic molecules and drives practically important phenomena such as …

This account aims at providing an understanding of singlet fission, ie, the photophysical
process of a singlet state (S1) splitting into two triplet states (2× T1) in molecular …

Singlet fission is a photophysical reaction in which a singlet excited electronic state splits
into two spin-triplet states. Singlet fission was discovered more than 50 years ago, but the …

Singlet exciton fission is a carrier multiplication process in organic semiconductors that
generates two electron–hole pairs for each photon absorbed. Singlet fission occurs on sub …

Singlet fission (SF) is a photophysical downconversion pathway, in which a singlet excitation
transforms into two triplet excited states. As such, it constitutes an exciton multiplication …

This review article focuses on the understanding of intersystem crossing (ISC) in molecules.
It addresses readers who are interested in the phenomenon of intercombination transitions …

Over the last several decades, exploring the pathways to access the triplet excited states of
organic chromophores has been a stimulating area of research. Among the numerous …

The quintet triplet-pair state may be generated upon singlet fission and is a critical
intermediate that dictates the fate of excitons, which can be exploited for photovoltaics …

Novel approaches to modify the spectral output of the sun have seen a surge in interest
recently, with triplet–triplet annihilation driven photon upconversion (TTA-UC) gaining …
