Abstract

The invention provides an organic photovoltaic battery and a manufacturing method of the organic photovoltaic battery. The organic photovoltaic battery is characterized in that the organic photovoltaic battery is composed of an anode, an anode modification layer, first donor material, second donor material, acceptor material, a cathode modification layer and a cathode which are sequentially in a stacked up mode, the first donor material and the acceptor material form a heterojunction, the second donor material and the acceptor material form a heterojunction, the two heterojunctions are connected in parallel to form a device light absorption layer, and an optical band gap of the first donor material is larger than an optical band gap of the second donor material. The band gaps of the first donor material and the second donor material are reduced gradually to achieve complementary absorption of the incident light, and effective separation of excitions is achieved on the double-heterojunction interface. By means of the organic photovoltaic battery and the manufacturing method, the problems that the light absorption layer cannot absorb the light sufficiently and the excitions cannot be separated effectively are solved, the preparation process is simple, the prepared organic photovoltaic battery is of a double-heterojunction parallel structure, and the battery efficiency and performance are obviously superior to a battery of a single-heterojunction structure.
