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 …

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 …

The design of optimal light-harvesting (supra) molecular systems and materials is one of the
most challenging frontiers of science. Theoretical methods and computational models play a …

Exciton fission is a process that occurs in certain organic materials whereby one singlet
exciton splits into two independent triplets. In photovoltaic devices these two triplet excitons …

Exciton generation, migration, and dissociation are key processes that play a central role in
the design and operation of many organic optoelectronic devices. In organic photovoltaic …

Transport of nanoscale energy in the form of excitons is at the core of photosynthesis and
the operation of a wide range of nanostructured optoelectronic devices such as solar cells …

Singlet fission presents an attractive solution to overcome the Shockley–Queisser limit by
generating two triplet excitons from one singlet exciton. However, although triplet excitons …

Hybrid interfaces combining inorganic and organic materials underpin the operation of many
optoelectronic and photocatalytic systems and allow for innovative approaches to photon up …

Exciton transport in most organic materials is based on an incoherent hopping process
between neighboring molecules. This process is very slow, setting a limit to the performance …

This perspective article provides a comprehensive but organized tutorial introduction of the
kinetics related to photon upconversion (UC) by triplet–triplet annihilation (TTA)(TTA-UC) …
