A polymer containing thiophene-benzene-thiophene unit has the following formula as (I):
R1 represents C1 to C20 alkyl, R2 represents C1 to C20 alkyl, n is an integer from 10 to 100. An energy gap of the polymer containing thiophene-benzene-thiophene unit is narrow, and therefore the power conversion efficiency is improved greatly. A method of preparing the polymer containing thiophene-benzene-thiophene unit and a sorlar cell device using the polymer containing thiophene-benzene-thiophene unit are also provided.
