Abstract A class of II–VI semiconductors, especially CdTe, is a highly photo‐reactive compound that would be suitable for photovoltaic applications. However, being resistive material, CdTe produces considerable contact resistance and drastically reduces the efficiency devices. Introducing back surface field layer at region may significantly improve device's performance. This work investigates s...

The angular dependence of the spontaneous emission of CdTe quantum dots (QDs) inside a photonic crystal with a pseudogap is reported. The sensitive dependences of the radiative lifetime and the photoluminescence spectrum of CdTe QDs on the observation angle demonstrate the effect of the photonic bandgap on the spontaneous emission of the QDs.

Polycrystalline CdTe thin film preparation for CdTe solar cell devices are typically established as the basis for this market-leading solar cell technology. The effects of substrate temperature and atmosphere of deposition and annealing on polycrystalline CdTe thin film prepared by vapor transport deposition (VTD) have been investigated. In order to analyze CdTe-borosilicate single layer struct...

Semiconductor Quantum dots (QDs) have raised great attention because of their superior optical properties and wide utilization in biological and biomedical studies. More recently, there have been intense concerns on cytotoxicity assessment of QDs. Most QDs are made of heavy metal ions (e.g., Cd(2+)), which may result in potential in vitro toxicity that hampers their practical applications. In t...

Type-II core/shell CdTe/CdSe quantum dots (QDs) were synthesized in aqueous medium by employing thiol-capped CdTe QDs as core template and CdCl(2) and Na(2)SeSO(3) as shell precursors, respectively. Compared with the original CdTe cores, the core/shell CdTe/CdSe QDs showed an obvious red-shifted emission with the color-tune capability to the near-infrared (NIR) wavelength, because of the format...

A novel fluorescent nanosensor for Sb(3+) determination was reported based on thioglycolic acid (TGA)-capped CdTe quantum dot (QD) nanoparticles. It was the first antimony ion sensor using QD nanoparticles in a receptor-fluorophore system. The water-soluable TGA-capped CdTe QDs were prepared through a hydrothermal route, NaHTe was used as the Te precursor for CdTe QDs synthesis. Bovine serum al...

Multiple applications of nanotechnology, especially those involving highly fluorescent nanoparticles (NPs) or quantum dots (QDs) have stimulated the research to develop simple, rapid and environmentally friendly protocols for synthesizing NPs exhibiting novel properties and increased biocompatibility. In this study, a simple protocol for the chemical synthesis of glutathione (GSH)-capped CdTe Q...

Experimental evidence shows that non-shallow acceptor states defect complex VCd ClTe 0= and Cu substitution of Cd CuCd 0= play critical roles in p-doping of CdTe in CdS/CdTe thin film solar cells. In this work, two equations are presented by using graphic method, one to determine the limit of p-doping or hole density for such non-shallow acceptor levels, and another to show the quantitative rel...

This review paper summarises the key issues of CdTe and CdS/CdTe solar cells as observed over past four decades, focuses on two growth techniques, electrodeposition (ED) closed space sublimation (CSS), which have successfully passed through commercialisation process. Comprehensive experience in electrical contacts to CdTe, surfaces & interfaces, electroplated cell development work led desig...
