A conjugated fluorene polymer is provided, which is defined by structure formula (1), wherein: R 1 , R 2 , R 3 , R 4 represent H or C 1 -C 20 alkyl, x+y=1, x‰ 0, y‰ 0, n is a natural number between 1-1000, Ar 1 is a group containing thiophene. A preparation method for the conjugated fluorene polymer and a solar cell device containing the conjugated fluorene polymer are also provided. Due to fluorene or its derivatives and conjugated structure, the conjugated fluorene polymer exhibits an excellent light stability and thermal stability. In addition, since thiophene and benzothiadiazole groups are introduced into the main chain of the polymer, the spectral response range of the polymer is broadened. |
