ZnO nanocrystals with a particle size of 20-30 nm have been synthesised for the first time using a template-free method. Chalcopyrite Cu0.28In1.72Se2.72 nanocrystals (5-10 nm) were directly anchored on ZnO nanocrystals by a vacuum one-pot-nanocasting process without any long ligands. We further investigated Cu0.28In1.72Se2.72 quantum dots and dye bilayer-sensitized solar cells, which exhibited power conversion efficiency of 57.4% higher than the single-dye-sensitized solar cells.
