Singlet fission can potentially break the Shockley–Queisser efficiency limit in single-junction solar cells by splitting one photoexcited singlet exciton (S1) into two triplets (2T1) in organic semiconductors. A dark multiexciton state has been proposed as the intermediate connecting S1 to 2T1. However, the exact nature of this multiexciton state, especially how the doubly excited triplets interact, remains elusive. Here we report a quantitative study on the magnetic dipolar interaction between… 

Anisotropic Geminate and Non-Geminate Recombination of Triplet Excitons in Singlet Fission of Single Crystalline Hexacene.

Singlet fission is known to improve solar energy utilization by circumventing the Shockley-Queisser thermodynamic limit. Understanding of triplet exciton generated by singlet fission is essential for

Transport of Spin-Entangled Triplet Excitons Generated by Singlet Fission.

Temperature-dependent ultrafast transient absorption microscopy is employed to image the transport of singlet fission intermediates in single crystals of tetracene and indicates that 1[TT] could transport with a similar mechanism as the bright singlet excitons, which has important implications in designing materials for singlets fission and spintronic applications.

Vibronic exciton theory of singlet fission. I. Linear absorption and the anatomy of the correlated triplet pair state.

This work forms a model in which both electronic and vibrational degrees of freedom are treated microscopically and non-perturbatively, and uses pentacene as a prototypical material for singlet fission, and subjects the theory to comparison with measurements on polarization-resolved absorption of single crystals.

Weakly coupled triplet pair states probed by quantum beating in delayed fluorescence in tetracene crystals.

It is argued that the triplet pairs probed by the quantum beat spectrum are weakly coupled, i.e., the spatially separated 1(T⋯T) state which is valuable for elucidating the intrinsic mechanism of singlet fission.

Mechanism for singlet fission in pentacene and tetracene: from single exciton to two triplets.

This ab initio study characterizes the low-lying excited states in acene molecular crystals in order to describe how SF occurs in a realistic crystal environment and shows how intermolecular interactions are shown to localize the initially delocalized bright state onto a pair of monomers.

Temperature-independent singlet exciton fission in tetracene.

Together, these results require that singlets and triplet pairs in tetracene are effectively degenerate in energy, and begin to reconcile the temperature dependence of many macroscopic observables with a fission process which does not require thermal activation.

This work lays the foundation for tailoring molecular properties like solubility and energy level alignment while maintaining the high fission yield required for photovoltaic applications.

Singlet fission in pentacene through multi-exciton quantum states.

It is shown that singlet fission to produce a pair of triplet excitons must involve an intermediate state that has a multi-exciton character, is energetically accessible from the optically allowed excited state, and efficiently dissociates into multiple electron-hole pairs.

The energy barrier in singlet fission can be overcome through coherent coupling and entropic gain.

This work attributes entropic gain in crystalline tetracene as the driving force for the subsequent decay of S(1) ⇔ ME into 2 × T(1), which leads to a high singlet-fission yield.
