Ag nanoparticle-deposited TiO(2) nanotube arrays for electrodes of Dye-sensitized solar cells

ABSTRACT: Dye-sensitized solar cells composed of a photoanode of Ag nanoparticle (NP)-deposited TiO(2) nanotube (TNT) arrays were fabricated. The TNT arrays were prepared by anodizing Ti films on fluorine-doped tin oxide (FTO)-coated glass substrates. Efficient charge transportation through the orde...

description ABSTRACT: Dye-sensitized solar cells composed of a photoanode of Ag nanoparticle (NP)-deposited TiO(2) nanotube (TNT) arrays were fabricated. The TNT arrays were prepared by anodizing Ti films on fluorine-doped tin oxide (FTO)-coated glass substrates. Efficient charge transportation through the ordered nanostructure of TNT arrays should be carried out compared to conventional particulate TiO(2) electrodes. However, it has been a big challenge to grow TNT arrays on FTO glass substrates with the lengths needed for sufficient light-harvesting (tens of micrometers). In this work, we deposited Ag nanoparticles (NPs) on the wall of TNT arrays to enhance light-harvesting property. Dye-sensitized solar cells with these Ag NP-deposited TNT arrays yielded a higher power conversion efficiency (2.03 %) than those without Ag NPs (1.39 %).
