Sol-modified ZnO photoanode for highly-efficient quantum dots sensitized solar cells

Influence of wide band gap oxide substrates on the photoelectrochemical properties and structural disorder of CdS nanoparticles grown by the successive ionic layer adsorption and reaction (SILAR) method

“…Along with the photoelectrochemical investigation, Raman spectroscopy was used to characterize CdS NPs. Raman spectroscopy in the simplest case can be applied as a type of phase analysis [ 16 – 17 ]. At the same time, in the general case, Raman spectra are determined by both phonon and electron spectra of the system under study, electron–phonon coupling, material defectiveness, and elastic stresses, providing therefore valuable information about the NP properties.…”

Sol-gel CdS layer for TiO2 nanorod-based quantum dots-sensitized solar cells

“…And to enhance the intensity of the intense peaks, we increased the deposited thickness of the CdS. The Raman spectroscopy revealed the rutile nature of the asprepared TiO 2 NRs from the intense peaks located at 236, 447, and 612 cm -1 [26]. After CdS deposition, a peak located at 303 cm -1 was present in the Raman spectra of the SG-CdS and CBD-CdS samples [27].…”

Facile synthesis of ZnO hollow microspheres and their high performance in photocatalytic degradation and dye sensitized solar cells

“…Due to the excellent bulk electron mobility (usually more than one order of magnitude larger than the anatase TiO 2 ) and the sophisticated fabrication methods, ZnO has been regard as the most promising alternative for the generally used TiO 2 materials [33][34][35]. Therefore, large varieties of ZnO based materials obtained from different synthetic routs were used as the photoanode materials for DSSCs [36][37][38][39][40] and the highest power conversion efficiency (PCE) for ZnO based DSSC has reached to $7.5% [41]. However, compared with the record of TiO 2 based DSSCs, it remains at a relative lower level.…”
