    A bilayered ZnO photoanode was constructed for dye-sensitized solar cells with a high conversion efficiency of 4.0%. One layer made of ZnO nanocrystallites increases dye adsorption, and the other consisting of ZnO nanorod aggregates provides a directed electron pathway for the electron transport together with a prominent aggregation-induced light scattering.
