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…

Slow Relaxation of Photogenerated Charge Carriers Boosts Open-Circuit Voltage of Organic Solar Cells
Tanvi Upreti, Sebastian Wilken, Huotian Zhang +1
Among the parameters determining the efficiency of an organic solar cell, the open-circuit voltage () is the one with most room for improvement. Existing models for th…
