The invention relates to a method for preparing a dye-sensitized solar cell photoanode added with an Ag/C (silver/carbon) nanometer cable. The method comprises the following steps of adopting a one-step hydrothermal synthesis method to prepare a one-dimensional Ag/C nanometer cable, and adding the nanometer cable into the traditional dye-sensitized solar cell photoanode, so as to prepare the dye-sensitized solar cell photoanode added with the Ag/C nanometer cable. One end of an Ag core of the nanometer cable is in contact with titanium dioxide P25, and the other end of the Ag core is in direct contact with conductive glass, so as to effectively separate electrons from holes. On one hand, the sufficient number of photoproduced electrons can be generated, and on the other hand, the electrons can be axially and directionally transmitted, the generation of composite reaction of charges is effectively inhibited, and the transmission rate of the electrons in a photoanode film is higher.
