Thiophene-based narrow band gap conjugated polymers with good stability and machinability for Solar cell applications have been the hot topic of new solar cells. This paper mainly introduced research progress of narrow band gap conjugated polymers for solar cells. According to the structure characteristics, the narrow band gap conjugated polymer was divided into alkyl- or alkoxy- substituted polythiophene, polyisothianaphthene, thiophene-based copolymers, pyrazine, thiazole, phenothiazine, fluorene and others. And their structural characteristics, optical band gap, synthesis methods were summarized. In addition, the existing problems and the further trend of this kind of materials in this field have also been discussed in this paper.
