چکیده
A poly(3,4-ethylenedioxythiophene)-b-poly(ethylene glycol) (PEDOT-b-PEG) block copolymer doped with perchlorate on FTO shows excellent optical and interfacial performance as a counter electrode (CE), such as low charge transfer resistance and low reflectivity for polymer electrolyte-based solid-state dye-sensitized solar cells (DSCs), resulting in 8.45% energy conversion efficiency, greater than the common Pt CE, via a facile room-temperature process.

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...
متن کاملInfluence of nanostructured TiO2 film thickness on photoelectrode structure and performance of flexible Dye- Sensitized Solar Cells
A commercial Ti-Nanoxide was deposited on In-doped SnO2 (ITO) polymer substrates by tape casting technique with different thicknesses (7, 14 and 36μm) to be used as photoelectrode in flexible dye-sensitized solar cells (DSSCs). Ruthenium dye was adsorbed on each TiO2 film for 24 h. The resulting photoelectrodes were used to form flexible DSSCs in combination with...

متن کاملIron pyrite thin film counter electrodes for dye-sensitized solar cells: high efficiency for iodine and cobalt redox electrolyte cells.
Iron pyrite has been the material of interest in the solar community due to its optical properties and abundance. However, the progress is marred due to the lack of control on the surface and intrinsic chemistry of pyrite. In this report, we show iron pyrite as an efficient counter electrode (CE) material alternative to the conventional Pt and poly(3,4-ethylenedioxythiophene (PEDOT) CEs in dye-...
متن کاملComparison of Transparent Nickel Doped Cobalt Sulfide and Platinum Counter Electrodes Used in Quasi-Solid State Dye Sensitized Solar Cells
Transparent nickel doped cobalt sulfide was fabricated on a SnO2:F electrode and tested as an efficient electrocatalyst and as an alternative to the expensive platinum counter electrode. In order to investigate how this electrode could affect the electrical characteristics of a dye-sensitized solar cell, we manufactured cells with the same TiO2 photoanode sensitized with dye (N719) and employin...
