摘要：

Novel benzo[1,2-b: 4,5-b'] dithiophene-based polymer (P1) is designed and synthesized for panchromatic polymer solar cells. The synthesis, thermal stability, as well as the optical and photovoltaic properties of the polymer is systematically investigated. The polymer was thermally stable up to 310 degrees C, and readily soluble in common organic solvent. Conventional polymer solar cell with the configuration ITO/PEDOT: PSS/polymer: PC71BM/Ca/Al is fabricated. A polymer solar cell device prepared using P1 as the active layer exhibited a power conversion efficiency of 3.27% with an open circuit voltage of 0.76 V, a short-circuit current density of 9.03 mA/cm(2), and a fill factor of 0.47 under AM 1.5G (100 mW/cm(2)) conditions.
