Electrostatic Layer-by-layer Assembly of Amphoteric Titanium Dioxide Nanoparticles for Dye-sensitized Solar Cells

摘要

Using nanocrystalline TiO_2(nc-TiO_2)as amphoteric charged particles,and two weak polyelectrolytes:poly(allylamine hydrochloride)(PAH),poly(acrylic acid,sodium salt)(PAA)and two strong polyelectrolytes:poly(dimethyldiallylammonium chloride)(PDAC),poly(sodium 4-styrenesulfonate)(PSS)as charged binders respectively,nanocomposite polyion/nc-TiO_2 multilayered films were prepared via the electrostatic layer-by-layer(ELBL)technique.
