Abstract
A novel copolymer based on alternating fluorene and donor–acceptor–donor segments is reported, together with its photovoltaic properties in blends with fullerene derivatives. The balanced electron and hole mobility of the blends leads to a power-conversion efficiency of 2–3% under solar illumination.
