CdS/CdSe quantum dots co-sensitized solar cells (QDSCs) were prepared by combining the successive ion layer absorption and reaction (SILAR) method and chemical bath deposition (CBD) method for the fabrication of CdS and CdSe quantum dots, respectively. In this work, we designed anisotropic nanostructure ZnO photoelectrodes, such as nanorods/nanosheets and nanorods array, for CdS/CdSe quantum dots co-sensitized solar cells. Our study revealed that the performance of QDSCs could be improved by modifying surface of ZnO to increase the loading of quantum dots and reduce the charge recombination.

The optical properties and photovoltaic characterization of CdS quantum dots sensitized solar cells (QDSSCs) were studied. CdS QDs were prepared by the chemical solution deposition (CD) technique. Photoacoustic spectroscopy (PA) was employed to study the optical properties of the prepared samples. The sizes of the CdS QDs were estimated from transmission electron microscope (TEM) micrographs gives radii ranged from 1.57 to 1.92 nm. The current density-voltage (J-V) characteristic curves of the assembled QDSSCs were measured. Fluorine doped Tin Oxide (FTO) substrates were coated with 20 nm-diameter TiO2nanoparticles (NPs). Presynthesized colloidal CdS quantum dots of different particles size were deposited on the TiO2-coated substrates using direct adsorption (DA) method. The FTO counter electrodes were coated with platinum, while the electroelectrolyte containingI-/I-3redox species was sandwiched between the two electrodes. The short current density (Jsc) and efficiency (η) increases as the particle size increases. The values ofJscincreases linearly with increasing the intensities of the sun light which indicates the greater sensitivity of the assembled cells.

In this study, we have prepared and investigated the optical properties of the TiO2/CdS:Mn2+/CdSe photoanode as the function of Mn2+ doping concentration and thickness. The results show that the peaks of the UV-Vis spectra shifted toward longer wavelength while Mn2+ doping concentrations or thickness of the films were changed. The main cause of the red-shifting in UV-Vis spectra may come from the increasing of photoanode light-harvesting capacity. In addition, the results also demonstrated by the boosting performance of quantum dots sensitized solar cells from 2.07% for TiO2/CdS/CdSe photoanode to 2.5% for TiO2/CdS:Mn2+/CdSe photoanode.
