AbstractFour novel two-dimensional (2D) donor-acceptor (D-A) type copolymers with different conjugated side chains, P1, P2, P3, and P4 (see Fig. 1), are designed and synthesized for the application as donor materials in polymer solar cells (PSCs). To the best of our knowledge, there were few reports to systematically study such 2D polymers with D-A type main chains in this area. The optical energy band gaps are about 2.0 eV for P1-P3 and 1.67 eV for P4. PSC devices using P1-P4 as donor and [6,6]-phenyl-C(61)-butyric acid methyl ester as acceptor in a weight ratio of 1:3 were fabricated and characterized to investigate the photovoltaic properties of the polymers. Under AM 1.5 G, 100 mA/cm(2) illumination, a high open-circuit voltage (V(oc)) of 0.9 V was recorded for P3-based device due to its low HOMO level, and moderate fill factor was obtained with the best value of 58.6% for P4-based device, which may mainly be the result of the high hole mobility of the polymers (up to 1.82 x 10(-3) cm(2)/V s).
