A star-shaped triphenylamine pi-conjugated system with internal charge-transfer as donor material for hetero-junction solar cells.
Introduction of dicyanovinyl groups on a triphenylamine-based conjugated system leads to an intramolecular charge transfer which extends the spectral response and raises the open-circuit voltage of the resulting hetero-junction solar cells.
