TL;DR: It is clearly demonstrated that singlet fission and its conjugate process, triplet-triplet annihilation, occur at a longer intermolecular distance than an excimer intermediate would impute, establishing that an endothermic singlet-fission material must be designed to avoid excimer formation, thus allowing singlets fission to reach its full potential in enhancing photovoltaic energy conversion.

TL;DR: In this article, it was shown that spin-2 triplet-pair states can also play a major role in polariton dynamics, observing polariton population transferred directly from the triplet manifold via triplet triplet annihilation.

TL;DR: In this paper, the triplet-state violanthrone chromophores luminesce in the visible spectrum following energy delivery from two singlet oxygen molecules, and the upconversion of light with photon energy below the silicon bandgap has been demonstrated using PbS semiconductor nanocrystals.

TL;DR: This approach demonstrates that it is possible to convert the exciton multiplication process of singlet fission into a photon multiplication process and provides a new path to harness singlets fission with photovoltaics.

TL;DR: In this paper, the authors used resources of the Advanced Photon Source, a U.S. Department of Energy (DOE) Office of Science User Facility operated for the DOE OSS by Argonne National Laboratory under Contract No. DE-AC02-06CH11357.
