Electrodeposition of zinc oxide/tetrasulfonated copper phthalocyanine hybrid thin film for dye-sensitized solar cell application

► Hybrid film of zinc oxide and tetrasulfonated copper phthalocyanine (TSPcCu) was prepared by using constant-current electrodeposition method. ► The nanosheets stack of ZnO leads to a porous surface structure and the TSPcCu was uniformly covered on the surface of ZnO crystallites. ► The TSPcCu plays a significant role in enhancing photovoltaic performance. ► The hybrid film of ZnO/TSPcCu shows a three-fold improvement in energy conversion efficiency than that the only ZnO film.
