Efficient Light Harvesting and Charge Collection of Dye-Sensitized Solar Cells with (001) Faceted Single Crystalline Anatase Nanoparticles Feng Hao Xiao Wang Chen Zhou Xingjian Jiao Xin Li Jianbao Li Hong Lin 10.1021/jp3053967.s001 https://acs.figshare.com/articles/journal_contribution/Efficient_Light_Harvesting_and_Charge_Collection_of_Dye_Sensitized_Solar_Cells_with_001_Faceted_Single_Crystalline_Anatase_Nanoparticles/2486959 With a comparable specific surface area, 17% enhanced dye-loading capacity was observed for the first time in the (001) faceted TiO<sub>2</sub> single crystals compared to that of benchmark P25 nanoparticles, thus generating a significant enrichment in both short-circuit photocurrent density and power conversion efficiency of dye-sensitized solar cells (DSCs). Such a remarkably increased dye-loading capacity was primarily ascribed to the higher density of 5-fold-coordinnated Ti atoms on the (001) surfaces. Furthermore, kinetic studies revealed that such single crystals confer a higher electron lifetime and charge collection efficiency compared with conventional P25 electrode, which might originate from the specific surface configuration in these high energetic facet dominant single crystals. Our study provides straightforward evidence for the superior reactivity of (001) facets and implies that such single TiO<sub>2</sub> crystals with high-energetic facets would be a promising electrode material for DSCs. 2012-09-13 00:00:00 TiO 2 crystals surface area electrode material facet power conversion efficiency capacity P 25 electrode benchmark P 25 nanoparticles DSC charge collection efficiency electron lifetime Charge Collection density Efficient Light Harvesting surface configuration
