“Organics strike back”: After a long halt between 2012 and 2015 on efficiencies around 12%, organic solar cells (OSC) have now transitioned to a stage where efficiencies over 18% are being regularly reported. The emergence of a family of materials - the non-fullerene acceptors (NFAs) with small energetic offsets with specific electron donors - is mainly responsible for the remarkable improvement. With the significant milestone of 20% now in sight and an optimistic value of 25% predicted, understanding interlayer, morphology, charge dynamics and the current barriers in these systems is now of great importance.
This symposium endeavours to gather leading experts from around the world aiming at critical discussions on hot topics related organic solar cells, in particular those based on NFAs.
