Dye-sensitized solar cells (DSCs) using anatase TiO2 nanocrystals exposing a specific lattice plane on the surface were studied. It was found that dye adsorption strongly depends on the lattice plane exposed on the TiO2 nanocrystal surface, which greatly affects DSC performance. TiO2 nanocrystals exposing mainly the (010) plane have a higher dye adsorption capacity and a higher V-oc for DSC than normal spherical nanocrystals. TiO2 nanocrystals with a large adsorption constant K-ad can yield a high J(sc). The highest J(sc) (20.6 mA/cm(2)) was achieved by using TiO2 nanocrystals with the specific lattice plane on the surface.
