Nitrogen-doped carbon nanotubes with metal nanoparticles as counter electrode materials for dye-sensitized solar cells.
نویسندگان
چکیده
Nitrogen-doped carbon nanotubes decorated with Co and Ni metal nanoparticles were assessed as counter electrodes (CEs) of dye-sensitized solar cells (DSSCs). These composites show good electrocatalytic activity toward the counter electrode reduction reaction (I3(-)→ I(-)) in DSSCs. The resulting devices using these composites as CEs display photovoltaic performance as good as, or even better than Pt-based devices, indicating their potential for application in DSSCs.

Recent development of carbon nanotubes materials as counter electrode for dye-sensitized solar cells
Dye-sensitized solar cells present promising low-cost alternatives to the conventional Silicon (Si)-based solar cells. The counter electrode generally consists of Pt deposited onto FTO plate. Since Pt is rare and expensive metal, nanostructured carbonaceous materials have been widely investigated as a promising alternative to replace it. Carbon nanotubes have shown significant properties such...

Materials preparation. Synthesis of nitrogen-doped carbon nanotubes with confinement of Co or Ni nanoparticles was carried out according to previous reported. [1] In brief, dicyandiamide (12 mmol) was mixed with cobalt(II) chloride hexahydrate (CoCl 2 ·6H 2 O, 0.84 mmol). After grinding for 15 min, the homogeneous mixture was placed on an alumina boat and heated at 500 °C in a tube furnace for ...

Owing to their low-cost production, simple fabrication, and high energy conversion efficiency, dye-sensitized solar cells (DSSCs) have attracted much attention since Oregan and Gr tzel s seminal report in 1991. A typical DSSC device consists of a dye-adsorbed TiO2 photoanode, counter electrode, and iodide electrolyte. The counter (cathode) electrode plays a key role in regulating the DSSC devic...

In the current study, pure TiO2 and Cr-doped TiO2 (Cr@TiO2) nanoparticles were synthesized via sol-gel method and the resulting materials were applied to prepare the porous TiO2 electrodes for dye-sensitized solar cells (DSSCs). It is hypothesized that the advantages of the doping of the metal ions into TiO2 lattice are the temporary rapping of the photogenerated electron-hole (charge carriers)...
