Delocalisation explains efficient transport and charge generation in neat Y6 organic photovoltaics
Daniel Balzer, Paul A. Hume, Geoffrey R. Weal +2
Non-fullerene acceptors (NFA), such as Y6, have significantly improved the efficiency of organic photovoltaic devices (OPVs). However, the fundamental processes behind the high eff…
Exciton diffusion in amorphous organic semiconductors: reducing simulation overheads with machine learning
Chayanit Wechwithayakhlung, Geoffrey R. Weal, Yu Kaneko +3
Simulations of exciton and charge hopping in amorphous organic materials involve numerous physical parameters. Each of these parameters must be computed from costly ab initio calcu…
Extracting Quantitative Dielectric Properties from Pump-Probe Spectroscopy
Arjun Ashoka, Ronnie R. Tamming, Aswathy V. Girija +12
Optical pump-probe spectroscopy is a powerful tool for the study of non-equilibrium electronic dynamics and finds wide applications across a range of fields, from physics and chemi…
Efficient Energy Transport in an Organic Semiconductor Mediated by Transient Exciton Delocalization
Alexander J. Sneyd, Tomoya Fukui, David Palecek +15
Efficient energy transport is highly desirable for organic semiconductor (OSC) devices such as photovoltaics, photodetectors, and photocatalytic systems. However, photo-generated e…
Bandgap Control in Two-Dimensional Semiconductors via Coherent Doping of Plasmonic Hot Electrons
Yu-Hui Chen, Ronnie R. Tamming, Kai Chen +6
Bandgap control is of central importance for semiconductor technologies. The traditional means of control is to dope the lattice chemically, electrically or optically with charge c…
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…
