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…

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…
