The invention belongs to the technical field of polymer solar cells and particularly relates to a reciprocal form electrode polymer solar cell using TiO2 as an electronic transmission layer, CuPc as a cavity transmission layer and a preparation method thereof. The method includes the steps of: using sol-gel technology to grow a layer of uniform and compact nanocrystal titanium dioxide (TiO2) film on an ITO glass substrate, then spin-coating a layer of P3HT:PCBM solution dissolved by dichlorobenzene, after annealing, using thermal evaporation to grow a layer of CuPc with certain thickness and finally evaporating Au electrode. The polymer solar cell prepared by utilizing the method solves two problems of the traditional polymer solar cell, namely that the mixed solution of 3, 4-EDOT and polystyrolsulfon acid corrode the surface of ITO glass, and the excessive thinness of cathode buffer layer LiF causes the operating process to be difficult to be controlled accurately.
