J. H. Kim and co‐workers present an effective method to prepare hierarchical double‐shell nanostructures consisting of TiO 2 nanosheets on SnO 2 hollow spheres. On page 5037, these nanostructures display a large surface area, excellent electron transport, and improved light scattering. The resulting dye‐sensitized solar cells with a solid electrolyte show an enhanced efficiency of up to 8.2% at 100 mW cm −2 .
