摘要：

The synthesis, characterization, and photophysical and photovoltaic properties of two anthracene-containing wide-band-gap donor and acceptor (D-A) alternating conjugated polymers (P1 and P2) are described. These two polymers absorb in the range of 300-600 nm with a band gap of about 2.12 eV. Polymer solar cells with P1:PC71BM as the active layer demonstrate a power conversion efficiency (PCE) of 2.23% with a high V-oc of 0.96 V, a J(sc) of 4.4 mA cm(-2), and a comparable fill factor (FF) of 0.53 under simulated solar illumination of AM 1.5 G (100 mW cm(-2)). In addition, P2:PC71BM blend-based solar cells exhibit a PCE of 1.42% with a comparable V-oc of 0.89 V, a J(sc) of 3.0 mA cm(-2), and an FF of 0.53.
