Polymeric materials are promising for solar cell applications. High‐molecular‐weight and soluble poly[N‐9'‐heptadecanyl‐2,7‐carbazole‐ alt ‐5,5‐(4',7'‐di‐ 2‐thienyl‐2',1',3'‐benzothiadiazole)] is synthesized by either a Stille or Suzuki coupling reaction. Electrochemical and optical characterization of this thermally and air‐stable polymeric material is reported, and bulk heretojunction polymer/fullerene photovoltaic devices are fabricated.
