Anatase TiO2 hierarchical structures composed of ultra-thin nano-sheets exposing high percentage {0Â 0Â 1} facets and their application in quantum-dot sensitized solar cells

TiO2 hierarchical structures assembled from ultra-thin nanosheets exposing ∼90% {0 0 1} facets were employed as photoanode materials to improve the performance of CdS/CdSe co-sensitized solar cells.
