Purifying Cadmium Telluride

Improvements in the purification of cadmium telluride by ...

01/11/1970· Several improvements have been made in the vertical zone re- fining technique used for the purification of cadmium telluride. The graphite susceptor used in RF heating is a split ring instead of the full ring used previously. Therefore, the molten zone is 1. Introduction Cadmium telluride seems to be the most promising semiconductor material to succeed Ge(Li) for detectors in v-ray ...

Improvements in the purification of cadmium telluride by ...

Several improvements have been made in the vertical zone refining technique used for the purification of cadmium telluride. The graphite susceptor used in RF heating is a split ring instead of the full ring used previously. Therefore, the molten zone is heated by direct RF coupling rather than by thermal radiation from the susceptor. An RF power of only 300-400 W is sufficient for refining ...

The trapping substance is tellurium or cadmium telluride for the purification of cadmium, and cadmium or cadmium telluride for the purification of tellurium. The amount of trapping material added must be less than the amount present in the eutectic composition of the corresponding side. The yield in slices cut in single crystals is greatly increased. Application to the manufacture of very pure ...

Cadmium telluride - Wikipedia

Cadmium telluride (CdTe) is a stable crystalline compound formed from cadmium and tellurium. It is mainly used as the semiconducting material in cadmium telluride photovoltaics and an infrared optical window. It is usually sandwiched with cadmium sulfide to form a p–n junction solar PV cell. Typically, CdTe PV cells use a n-i-p structure.

Cadmium telluride photovoltaics - Wikipedia

Cadmium telluride (CdTe) photovoltaics describes a photovoltaic (PV) technology that is based on the use of cadmium telluride in a thin semiconductor layer designed to absorb and convert sunlight into electricity. Cadmium telluride PV is the only thin film technology with lower costs than conventional solar cells made of crystalline silicon in multi-kilowatt systems. On a lifecycle basis, CdTe PV has the smallest carbon footprint, lowest water use and shortest energy p…

Cadmium Telluride - an overview | ScienceDirect Topics

Cadmium telluride (CdTe) (Bonnet (2012))is a direct-bandgap semiconductor with that bandgap well matched to the solar spectrum. CdTe thin-film laboratory cell efficiency of 18.3% has been achieved, and the record module efficiency currently stands at 15.3%. World production is dominated by a single company, First Solar. The basic structure Figure 11) has a glass superstrate and a layer of ...

Impurity reduction technique for mercury cadmium …

Abstract. The disclosure relates to a method for reducing impurity concentration in mercury cadmium telluride alloys wherein impurities are attracted to a region saturated with second phase tellurium during annealing in a saturated mercury atmosphere where the second phase tellurium and the impurities attracted thereto can be removed by polishing, etching, grinding, or the like.

ENVIRONMENTAL LIFE CYCLE ASSESSMENT OF CADMIUM TELLURIDE ...

The life-stages of the cadmium compounds involve:1) production of raw materials (Cd and Te), 2) purification of Cd and Te, 4) production of CdTe, 5) manufacture of CdTe PV modules, 6) use of CdTe PV modules, and 7) disposal of spent modules. A detailed description of these phases can be found in a recent review article [1]. 2. CADMIUM PRODUCTION
