Preparation and performance of g-C3N4/CuS film as counter electrode for quantum dot sensitized solar cells

نویسندگان

چکیده

In this work g-C3N4/CuS composite film was prepared by successive ion layer adsorption and reaction (SILAR) method used as the counter electrode in quantum dot sensitized solar cell (QDSSCs). To configure cell, CdSe CdS dots acted sensitizers on photoanode side, polysulphide electrolyte copper sulphide deposited into g-C3N4 structure side. Scanning electron microscope X-ray diffraction were to characterize morphology of materials, respectively. The photovoltaic performance analysed a standard simulator. results revealed that photoelectric conversion efficiency reached 3.65% under condition AM 1.5 irradiation intensity 100mW/cm2.

Reactively sputtered nickel nitride as electrocatalytic counter electrode for dye- and quantum dot-sensitized solar cells

Nickel nitride electrodes were prepared by reactive sputtering of nickel under a N2 atmosphere at room temperature for application in mesoscopic dye- or quantum dot- sensitized solar cells. This facile and reliable method led to the formation of a Ni2N film with a cauliflower-like nanostructure and tetrahedral crystal lattice. The prepared nickel nitride electrodes exhibited an excellent chemic...

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...

SILAR Sensitization as an Effective Method for Making Efficient Quantum Dot Sensitized Solar Cells

CdSe quantum dots were in situ deposited on various structures of TiO2 photoanode by successive ionic layer adsorption and reaction (SILAR). Various sensitized TiO2 structures were integrated as a photoanode in order to make quantum dot sensitized solar cells. High power conversion efficiency was obtained; 2.89 % (Voc=524 mV, Jsc=9.78 mA/cm2, FF=0.56) for the cells that sensitized by SILAR meth...

Effect of PbS Film Thickness on the Performance of Colloidal Quantum Dot Solar Cells

Colloidal quantum dots offer broad tuning of semiconductor band structure via the quantum size effect. In this paper, we present a detailed investigation on the influence of the thickness of colloidal lead sulfide (PbS) nanocrystals (active layer) to the photovoltaic performance of colloidal quantum dot solar cells. The PbS nanocrystals (QDs) were synthesized in a non-coordinating solvent, 1-oc...
