A novel hierarchical ZnO disordered/ordered bilayer nanostructured film for dye sensitized solar cells.

Highlights: [•] A novel hierarchical ZnO structure film was fabricated on a FTO substrate. [•] Hierarchical ZnO film is applied as the electrodes for dye sensitized solar cells. [•] The film possess high specific surface area and fast electron transport effect. [•] The light-scattering effect of the hierarchical film is pronounced. [•] The energy conversion efficiency of hierarchical ZnO electrode reaches to 5.16%. [ABSTRACT FROM AUTHOR]
