Abstract

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.
