NOVELTY - The photovoltaic device comprises a multilayer structure for generating and transporting charge. The multilayer structure comprises a substrate, an anode layer, a hole transporting layer, a first nanostructure/conjugated polymer hybrid layer, a network-shaped electron transporting layer matched to the hybrid layer, and a cathode layer. The electron transporting layer is composed of second nanostructures that are staked on each other so as to form an interconnecting network. A material of the first nanostructure is as same as the second nanostructure.    USE - Used as a photovoltaic device.    ADVANTAGE - The photovoltaic device can be economically and effectively manufactured with enhanced performance, excellent quantum efficiency and high stability.    DETAILED DESCRIPTION - The photovoltaic device comprises a multilayer structure for generating and transporting charge. The multilayer structure comprises a substrate, an anode layer, a hole transporting layer, a first nanostructure/conjugated polymer hybrid layer, a network-shaped electron transporting layer matched to the hybrid layer, and a cathode layer. The electron transporting layer is composed of second nanostructures that are staked on each other so as to form an interconnecting network. A material of the first nanostructure is as same as the second nanostructure or different from the second nanostructure. A cross section of the first and second nanostructures is 10-200 nm. The material of the first and second nanostructures independently consists of an inorganic material, a metal material and a mixture of metal and inorganic material. The material of the inorganic nanostructure comprises group II-VI, group III-V, group IV semiconductors and/or alloys. A bandgap of one oxide is less than or equal to 3.0 eV, and a sheet resistance of the other oxide is less than or equal to 100 Omega /sq. The first nanostructure content of the hybrid layer is 40-60 wt.%.    DESCRIPTION OF DRAWING(S) - The diagrams show a schematic view of a structure of a poly(2-methoxy-5-(2'-ethylhexyloxy)p-phenylenevinylene):titanium dioxide nanorod hybrid photovoltaic device.
