Abstract

High performance solar cells fabricated from an easily synthesized donor-acceptor polymer show maximum power point up to 6.0 mW cm−2, with an open-circuit voltage of 0.89 V, short-circuit current density of 10.5 mA cm−2 and fill factor of 0.64, making this polymer a particularly promising candidate for high-efficiency low-cost polymer solar cells.
