The invention provides a vanadium-copper composite oxide film, a preparation method and application thereof, and an organic solar cell, and belongs to the technical field of solar cells. The preparation method of the vanadium-copper composite oxide film provided by the invention is simple to operate, low in cost and beneficial to industrial mass production, the obtained vanadium-copper composite oxide is low in forbidden bandwidth, high in film light transmittance and high in charge transmission efficiency, and the conversion efficiency of a solar cell can be improved when the vanadium-coppercomposite oxide film is used as a hole transport layer. The organic solar cell provided by the invention takes the vanadium-copper composite oxide film as a hole transport material, and has good energy conversion efficiency. The embodiment result shows that the short-circuit current of the organic solar cell can reach 11.10mA.cm<-2> and the energy conversion efficiency can reach 4.21% when the vanadium-copper composite ox
