CHIMIA, 78(12), Article 12. https://doi.org/10.2533/chimia.2024.836https://hdl.handle.net/1911/118096Photon interconversion promises to alleviate thermalization losses for high energy photons and facilitates utilization of sub-bandgap photons – effectively enabling the optimal use of the entire solar spectrum. However, for solid-state device applications, the impact of intermolecular interactions on the energetic landscape underlying singlet fission and triplet-triplet annihilation upconversion cannot be neglected. In the following, the implications of molecular arrangement, intermolecular coupling strength and molecular orientation on the respective processes of solid-state singlet fission and triplet-triplet annihilation are discussed.engExcept where otherwise noted, this work is licensed under a Creative Commons Attribution (CC BY) license.
