Highly ordered TiN nanotube arrays as counter electrodes for dye-sensitized solar cells.

چکیده
TiN nanotube arrays, prepared by the anodization of metallic Ti foil substrate and subsequent simple nitridation in an ammonia atmosphere, were investigated as low-cost counter electrodes in dye-sensitized solar cells for the first time. It is found that the highly ordered TiN nanotube arrays on the metallic Ti foil substrate show an excellent performance, comparable with typical Pt counter electrodes.

Dye-sensitized TiO2 nanotube solar cells: rational structural and surface engineering on TiO2 nanotubes.
Owing to well-defined structural parameters and enhanced electronic properties, highly ordered TiO(2) nanotube arrays have been employed to substitute TiO(2) nanoparticles for use in dye-sensitized solar cells. To further improve the performance of dye-sensitized TiO(2) nanotube solar cells, efforts have been directed toward the optimization of TiO(2) photoanodes, dyes, electrolytes, and co...
متن کاملAg nanoparticle-deposited TiO2 nanotube arrays for electrodes of Dye-sensitized solar cells
ABSTRACT Dye-sensitized solar cells composed of a photoanode of Ag nanoparticle (NP)-deposited TiO2 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 TiO2 elec...

High-efficient fibrous dye-sensitized solar cell with carbon nanotube (CNT) thin films as counter electrodes has been reported. The CNT films were fabricated by coating CNT paste or spraying CNT suspension solution on Ti wires. A fluorine tin oxide-coated CNT underlayer was used to improve the adherence of the CNT layer on Ti substrate for sprayed samples. The charge transfer catalytic behavior...
