Direct assembly of preformed nanoparticles and graft copolymer for the fabrication of micrometer-thick, organized TiO2 films: high efficiency solid-state dye-sensitized solar cells.
Solid-state dye-sensitized solar cell with 7.1% efficiency at 100 mW/cm(2)  is reported, one of the highest observed for N719 dye. Excellent performance was achieved via a graft copolymer-templated, organized mesoporous TiO(2)  film with a large surface area using spindle-shaped, preformed TiO(2)  nanoparticles and solid polymer electrolyte.
