The method of successive ion layer adsorption and reaction was applied for the deposition of CdS nanoparticles onto a mesoporous In2O3 substrate. The filling of the nanopores in In2O3 films with CdS particles mainly occurs during the first 30 cycles of the SILAR deposition. The surface modification of In2O3 with CdS nanoparticles leads to the spectral sensitization of photoelectrochemical proce...

Despite the potential of PbS quantum dots (QDs) as sensitizers for quantum-dot-sensitized solar cells (QDSSCs), achieving a high photocurrent density over 30 mA cm(-2) remains a challenging task in PbS-sensitized solar cells. In contrast to previous attempts, where Hg(2+)-doping or multi-step post-treatment is necessary, we are capable of achieving a high photocurrent exceeding 30 mA cm(-2) sim...

A continuous and compact CdS quantum dot-sensitive layer was synthesized on TiO2 nanorods by successive ionic layer adsorption and reaction (SILAR) and subsequent thermal annealing. The thickness of the CdS quantum dot layer was tuned by SILAR cycles, which was found to be closely related to light absorption and carrier transformation. The CdS quantum dot-sensitized TiO2 nanorod array photoelec...

The CuO inverse opal photonic crystals (IOPCs) were synthesized by the sol-gel method and modified with CdS quantum dots by successive ionic layer adsorption and reaction (SILAR). CdS QDs modified CuO IOPCs FTO electrodes of different SILAR cycles were fabricated and their electrochemical properties were studied by cyclic voltammetry (CV) and chronoamperometry (I-t). Structure and morphology of...

CuInS(2) nanotube (NT) arrays were synthesized on indium tin oxide (ITO) substrates for the first time using a successive ionic layer absorption and reaction (SILAR) process with self-dissolved ZnO nanowire (NW) templates. The p-type CuInS(2) NT array shows promising conversion efficiency in a photoelectrochemical cell with polysulfide electrolyte.

Zinc Oxide (ZnO) thin film have been deposited using Successive Ionic Layer Adsorption and Reaction (SILAR) technique, which is based on alternate dipping of substrate in the solution and deionized water. The thin film was grown on glass substrate. The precursor for ZnO film was diluted aqueous solution of ZnSo4 complex with NH3. The film was investigated by X-ray diffraction, Scanning electron...

Zinc oxide nanowire and titanium dioxide nanoparticle (ZnO:TiO₂ NW/NP) hybrid films were utilized as the photoanode layer in quantum dot-sensitized solar cells (QDSSCs). CdSe quantum dots (QDs) with a ZnS passivation layer were deposited on the ZnO:TiO₂ NW/NP layer as a photosensitizer by successive ion layer adsorption and reaction (SILAR). Cells were fabricated using a solid-state polymer ele...

A solid-state environmentally friendly Ag2S quantum dot-sensitized solar cell (QDSSC) is demonstrated. The photovoltaic device is fabricated by applying ZnO@Ag2S core-shell nanowire arrays (NWAs) as light absorbers and electron conductors, and poly-3-hexylthiophene (P3HT) as a solid-state hole conductor. Ag2S quantum dots (QDs) were directly grown on the ZnO nanowires by the successive ionic la...

Vertically aligned TiO(2) nanorod arrays (NRAs) modified with Ag(2)S quantum dots (QDs) have been successfully prepared via a successive ionic layer adsorption and reaction (SILAR) process. Ultraviolet-visible (UV-vis) absorption spectra and surface photovoltage (SPV) measurements reveal that the Ag(2)S sensitization extends the range of the photoresponse of the TiO(2) NRAs to the visible regio...

Successive ionic layer deposition (SILD), also known as successive ionic layer adsorption and reaction (SILAR), is an aqueous method which exploits the electric double layer effect to create thin solid films on supports. In SILD, submonolayers of desired cations and anions are alternately and selectively adsorbed on a support material to produce SILD nanoislands or nanolayers with controlled co...
