A highly efficient ZnO photoanode for dye-sensitized solar cells (DSSCs) was successfully grown by a simple, low cost, and scalable method. A nanostructured coral-shaped Zn layer was deposited at room temperature sputtering technique and then thermally oxidized. ZnO-based DSSCs were fabricated with customized microfluidic architecture, and the dependence of the cell efficiency on sensitizer incubation time and film thickness was studied showing the promising properties of this material for the fabrication of photoanodes, with solar conversion efficiency up to 4.58%.
