“…Cadmium sulfide can be used as sensitizers in quantum dotsensitized solar cells. It also has application in nonlinear optics (Liu et al 2004), light-emitting diodes (Gopal et al 2009;Kar and Chaudhuri 2006), solar energy conversion (Weller 2003), thin film transistors (Duan et al 2003), gas detectors (Afify and Battisha 2000), optoelectronics (Hikmet et al 2003), photo catalysis (Huynh et al 2002), photovoltaic cells (Uda et al 1997), X-ray detectors (Frerichs 1950) and as a window material for hetero-junction solar cells because it has usually a high absorption coefficient (Oladeji et al 2000). Doping with transition metal elements into CdS nanoparticles leads to many interests.…”

Co 2? (1-5 and 10 %)-doped cadmium sulfide nanoparticles were synthesized by the chemical precipitation method using polyvinyl pyrrolidone (PVP) as a surfactant. The X-ray diffraction results showed that Co ions were successfully incorporated into the CdS lattice and the transmission electron microscopy results revealed that the synthesized particles were aligned as rod-like structures. The absorption spectra of all the prepared samples (undoped and doped) were significantly blue shifted (472-504 nm) from the bulk CdS (512 nm). However, the absorption spectra of the doped samples were red shifted (408-504 nm) with respect to the doping concentrations (1-5 and 10 %). Furthermore, a dramatic blue shift absorption is observed at 472 nm for PVP-capped CdS:Co 2? (4 %) nanoparticles. In the photoluminescence study, two emission peaks were dominated in the green region at 529 and 545 nm corresponding the CdS:Co 2? nanoparticles. By correlating optical and EPR spectral data, the site symmetry of Co 2? ion in the host lattice was determined as both octahedral and tetrahedral. The presence of functional groups in the synthesized nanoparticles was identified by Fourier transform infrared spectroscopy. The thermal stability of the Co ions in CdS nanoparticles was studied by TG-DTA. In addition, an electrochemical property of the undoped and doped samples was studied by cyclic voltammetry for electrode applications.

“…These types of compounds have attracted interest more than the other inorganic semiconductors due to their flexibility in the band gap tuning and ability in the particle size alteration. Cd 1-x Zn x S is a II-VI semiconductor and a promising and wide bandgap window material which has enormous applications in the photovoltaic field such as heterojunction photovoltaic solar cells [1] and various photoconductive devices [2]. The efficiency of solar cell strongly depends on the choice of an appropriate window material.…”

We fabricated quantum dot-sensitized solar cells (QDSSCs) using cadmium sulfide (CdS) and cadmium telluride (CdTe) quantum dots (QDs) as sensitizers. A spin coated TiO 2 nanoparticle (NP) film on tin-doped indium oxide glass and sputtered Au on fluorine-doped tin oxide glass were used as photo-anode and counter electrode, respectively. CdS QDs were deposited onto the mesoporous TiO 2 layer by a successive ionic layer adsorption and reaction method. Pre-synthesized CdTe QDs were deposited onto a layer of CdS QDs using a direct adsorption technique. CdS/CdTe QDSSCs had high light harvesting ability compared with CdS or CdTe QDSSCs. QDSSCs incorporating single-walled carbon nanotubes (SWNTs), sprayed onto the substrate before deposition of the next layer or mixed with TiO 2 NPs, mostly exhibited enhanced photo cell efficiency compared with the pristine cell. In particular, a maximum rate increase of 24% was obtained with the solar cell containing a TiO 2 layer mixed with SWNTs.
