Real-Time Observation of Exciton-Phonon Coupling Dynamics in Self-Assembled Hybrid Perovskite Quantum Wells
Limeng Ni, Uyen Huynh, Alexandre Cheminal +5
Self-assembled hybrid perovskite quantum wells have attracted attention due to their tunable emission properties, ease of fabrication and device integration. However, the dynamics…
Energy Efficient Dissociation of Excitons to Free Charges
Maxim Tabachnyk, Samuel L. Smith, Leah R. Weiss +4
In photovoltaics (PVs) and artificial photosynthetic systems based on excitons, the question of how energy must be lost in overcoming the Coulomb barrier, converting excitons to fr…
Ultrafast Triplet Pair Formation and Subsequent Thermally Activated Dissociation Control Efficient Endothermic Singlet Exciton Fission
Hannah L. Stern, Alexandre Cheminal, Shane R. Yost +12
Singlet exciton fission (SF), the conversion of one spin-singlet exciton (S1) into two spin-triplet excitons (T1), could provide a means to overcome the Shockley-Queisser limit in…
