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/cm2 is reported, one of the highest observed for N719 dye. Excellent performance was achieved via a graft copolymer‐templated, organized mesoporous TiO2 film with a large surface area using spindle‐shaped, preformed TiO2 nanopartic...

Description
Summary:Solid‐state dye‐sensitized solar cell with 7.1% efficiency at 100 mW/cm2 is reported, one of the highest observed for N719 dye. Excellent performance was achieved via a graft copolymer‐templated, organized mesoporous TiO2 film with a large surface area using spindle‐shaped, preformed TiO2 nanoparticles and solid polymer electrolyte.
