The electronic excited states of molecular aggregates and their photophysical signatures
have long fascinated spectroscopists and theoreticians alike since the advent of Frenkel …

The rapid development of the science and technology of organic semiconductors has
already led to mass application of organic light‐emitting diodes (OLEDs) in television …

The limited exciton lifetime (τ, generally< 1 ns) leads to short exciton diffusion length (LD) of
organic semiconductors, which is the bottleneck issue impeding the further improvement of …

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 …

The field of organic photovoltaics has developed rapidly over the last 2 decades, and small
solar cells with power conversion efficiencies of 13% have been demonstrated. Light …

The purpose of this review is to provide a basic physical description of the exciton diffusion
in organic semiconductors. Furthermore, experimental methods that are used to measure …

A survey is provided of recent progress in the understanding of singlet fission, a spin-
allowed process in which a singlet excited molecule shares its energy with a ground-state …

In the following we provide a comprehensive review of singlet fission in organic materials.
We first sketch an outline of the underlying theory and then turn to molecular crystals …

Singlet fission (SF) has the potential to supersede the traditional solar energy conversion
scheme by means of boosting the photon-to-current conversion efficiencies beyond the 30 …

Singlet exciton fission, the spin-conserving process that produces two triplet excited states
from one photoexcited singlet state, is a means to circumvent the Shockley–Queisser limit in …
