The invention belongs to the technical field of dye-sensitized solar cells, in particular to a preparation method of a polyaniline nanowire array counter electrode of a dye-sensitized solar cell. According to the invention, a polyaniline nanowire array is prepared through a method of oxidative polymerization, and is grown on a conductive substrate in situ, the polyaniline nanowire array is directly applied to the dye-sensitized solar cell, and energy exchange efficiency, which is better than pyrogenic decomposition of a platinum counter electrode, can be obtained through combination with a non-corrosive electrolyte. The preparation method, provided by the invention, has the advantages of simple process, and high catalytic activity and low price of the prepared non-platinum electrode, the cost of the electrode is greatly reduced, so that the composite cost of the dye-sensitized solar cell is reduced, and the preparation method is applied to industrial production of the large-scale dye-sensitized solar cells.
