The structural formula of the polymer is shown in the description, wherein EH is shown in the description, and n is 24-25. The prepared polymer PBDFFPD is high in conjugate plane, high inin-molecule and inter-molecule mutual action, and low in HOMO energy level; a PBDFTD:ITIC based organic solar cell has 9.30% of photoelectric conversion efficiency under the collaborative processing of chloronaphthalene and methyl alcohol, and FF is up to 70.3%, so that the top record of the photoelectric conversion efficiency of an FTD based polymer organic solar cell is reached. In addition, thedeviation between the average efficiency and the maximum efficiency of a 20 battery under the optimal condition of the PBDFTD:ITIC cell is kept at 0.64%, so that the PBDFFTD is high in potential to prepare an efficient organic solar cell, and the operation is free from strict requirements; the polymer is suitable for popularization.
