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.
