We report an inexpensive TiO2 based quantum dot solar cell (QDSSC) with improved power conversion efficiency prepared by simple techniques. Barium doped zinc sulfide has been successfully deposited on cadmium dots (QDs) successive ion layer adsorption and reaction (SILAR) technique. The is utilized as a passivation in the QDSSC, which helped better charge separation. copper (Cu2S) reduced graph...

High quality Cadmium Sulphide thin films were grown on directly heated substrates of commercial glass by means of Modified Chemical Bath Deposition. Structural and optical properties of the obtained films were achieved. The impact of heat treatment in air at 450°C for one hour reveals the apparition of nano films of Cadmium Oxide on the surface of these buffer layers, which decreases dramatical...

Scalable and sustainable solar hydrogen production through photocatalytic water splitting requires highly active and stable earth-abundant co-catalysts to replace expensive and rare platinum. Here we employ density functional theory calculations to direct atomic-level exploration, design and fabrication of a MXene material, Ti3C2 nanoparticles, as a highly efficient co-catalyst. Ti3C2 nanoparti...

Progress is reported towards the development of a new route to obtain cadmium sulfide (CdS) thin films by using ethylene-diamine-tetra-acetic acid (EDTA) ligand on the chemical bath deposition (CBD) method. Different chemical baths are used to study changes in the structures of the CdS films for different EDTA concentrations. X-ray diffraction (XRD) is used to prove the structural characterizat...

Cadmium sulfide (CdS) nanorods were synthesized by simple solvothermal reactions at 200 C for 12-24 h using Cd(NO3)2·4H2O and NH2CSNH2 as starting materials and (C2H5)2NH as solvent. XRD and TEM analysis show a hexagonal-phase single crystalline CdS nanorods with diameter of 20 nm and length of 100-200 μm. UV-visible absorption of as-prepared CdS nanorods presented an absorption peak of around ...

Improvement of polyvinyl alcohol stability against ultraviolet (UV) illumination is achieved by introducing cadmium sulfide (CdS) nanoparticles into the polymeric matrix. Enhancement of stability is analyzed by optical characterization methods. UV protection is achieved by diminishing the probability of photo-activated formation of defects in polymer. The sources of polymer protection are the l...

We report the observation of interband two-photon absorption (TPA) saturation in cadmium sulfide nanocrystals (CdS NCs) under intense femtosecond laser excitation with 1.6 eV photon energy. The observation has been compared to interband TPA saturation in bulk CdS under the same experimental conditions. By using both Z-scan techniques and transient absorption measurements, the saturation intensi...
