Quantum dynamic simulation of triplet formation in an effective model of Y6 (BTP-4F)
Isabel Creed, Lucy J. F. Hart, Pranay Venkatesh +2
We construct a five-state model for photoexcitation in Y6 (BTP-4F) dimers, and then solve the non-adiabtic dynamics using the Hierarchical Equations of Motion (HEOM) method. We fin…

More is Different: Mobile Ions Improve the Design Tolerances of Perovskite Solar Cells
Lucy J. F. Hart, Fraser J. Angus, Yin Li +5
Many recent advances in metal halide perovskite solar cell (PSC) performance are attributed to surface treatments which passivate interfacial trap states, minimise charge recombina…

Understanding the Role of Triplet-triplet Annihilation in Non-fullerene Acceptor Organic Solar Cells
Lucy J. F. Hart, Jeannine Grüne, Wei Liu +15
Non-fullerene acceptors (NFAs) have enabled power conversion efficiencies exceeding 19% in organic solar cells (OSCs). However, the open-circuit voltage of OSCs remains low relativ…
