Anthraquinone sulfonate modified, layered double hydroxide nanosheets for dye-sensitized solar cells

Abstract

Hybrid light sensitizer: The exfoliated, layered, double hydroxide nanosheets induced a strong photochrome function in the anthraquinone sulfonate anions that were chemically immobilized on the nanosheets. This hybrid nanosheet was applied to the dye-sensitized solar cell as a new light sensitizer that was self-organized on TiO2 spheres, resulting in a higher solar-toelectric conversion efficiency than the single-dye cell, owing to the intense photochromic function of the hybrid nanosheets.
