Abstract

The conjugated polymer AnE-PVstat demonstrates competitive photovoltaic characteristics compared with modern "push-pull" polymer systems. AnE-PVstat is distinguished by its PPV-type molecular structure, the absence of heterocyclic units, particularly thiophene rings, and the presence of an anthracene unit bearing two adjacent triple bonds. AnE-PVstat in combination with specially designed [60]fullerene derivatives F3 and F11 shows power conversion efficiencies of >4% in solar cells.
