The invention, which belongs to the polymer solar battery technology field, relates to a cathode modified material of a polymer solar battery and a battery using the modified material. The polymer solar battery comprises a substrate, an anode layer, an anode modification layer, a photoelectric active layer, a cathode modified layer and a cathode layer, wherein the above-mentioned layers are successively stacked; the cathode modification layer is an acetylacetone titanium oxide film; and the cathode modification material is acetylacetone titanium oxide. According to the invention, acetylacetone titanium oxide is used as a material of a cathode modification layer; a spin coating method is employed to prepare the cathode modification layer; the acetylacetone titanium oxide is introduced into a polymer solar battery, so that high efficient collection of electrons is realized. Moreover, compared with current titanium dioxide prepared by a sol-gel method and LiF obtained by vacuum evaporation, the acetylacetone tit
