Aug 22, 2019· The leading thin film photovoltaic technologies of today based on the chalcogenide materials, cadmium telluride (CdTe) and copper indium gallium selenide (CIGS), are considered to be low cost and widely deployable .But there are some serious concerns regarding both CdTe and CIGS: cadmium is highly toxic, and tellurium, gallium, and indium are extremely rare on our planet.

employing a liquid nitrogen cooled mercury−cadmium− telluride (MCT) detector was used. Background and sample scans were recorded by coadding 256 scans with a resolution of 4cm−1. The crystal surface was subjected to a cleaning process, consisting of oxygen cleaning, annealing, and Ar ion sputtering.
Abstract In this study, a subsonic molecular beam of Hg was directed on CdTe surfaces and the absorption spectra were measured for the first time by ellipsometry.
Behaviour of cadmium telluride in aqueous solutions under reductive conditions. Journal of Electroanalytical Chemistry and Interfacial Electrochemistry 1989, 269 (2), 305-322. DOI: 10.1016/0022-0728(89)85140-X. P. Allongue, E. Souteyrand.
The tellurium adsorption capacities of NZVFe obtained at various adsorption temperatures and times are displayed in Fig. 9B. As can be seen in Fig. 9B, the tellurium adsorption capacity increased from 68.61 mg/g to 83.57 mg/g accompanied by the temperature increased from 30 °C to 60 °C. It indicated that the tellurium adsorption process of ...
An in situ infrared spectroscopic study is described of the adsorption of 8-quinolinol, thiosulfate, thiosalicyclic acid and diethyldithiocarbamate from aqueous solution to cadmium telluride (CdTe) particle films. Adsorption isotherms and adsorption constants have been derived for 8-quinolinol and thiosulfate adsorbed to CdTe.
In the system, blue emissive carbon quantum dots wrapped with silica served as the internal reference signal for eliminating background interference, while red emissive thioglycolic acid modified CdTe quantum dots (CdTe QDs), which are low dimensional semiconductor materials by the combination of cadmium and tellurium with excellent optical ...
We adopted to determine maximum adsorption capacity of cadmium (II) ions by activated carbon, the adsorption of cadmium on the activated carbon has been realized on the solution from cadmium chloride. A solution of cadmium (II) ions of concentration 30 mg/L was prepared by dissolving 50 mg of CdCl2 in a 1000 mL volumetric flask.
