Thin-film CdTe cells: Reducing the CdTe

Thin Solid Films, 2011
Abstract Polycrystalline thin-film CdTe is currently the dominant thin-film technology in world-wide PV manufacturing. With finite Te resources world-wide, it is appropriate to consider the limits to reducing the thickness of the CdTe layer in these devices.

Structure of the CdTe/Cd0.959Zn0.041Te, Hg1−xCdxTe/CdTe, CdTe/GaAs heterojunctions

Journal of Crystal Growth, 1999
Abstract The strain tensor elements for an anisotropically relaxed CdTe epilayer at a low-symmetry (1 1 2) surface grown by molecular beam epitaxy (MBE) on the Cd 0.959 Zn 0.041 Te(1 1 2)B substrate were determined by X-ray double crystal diffraction (XDCD). It was obtained that the strain tensor elements are e xx =2.5×10 −3 , e zz =2.6×10 −3

RESEARCH ON CdTe

1963
Abstract : A final addition is given to the experimental study of the band edge of CdTe. This consists of an attempt to obtain the best possible fit of the CdTe data with the theory of indirect interband and indirect exciton absorption. The failure of this theory to account for the data is examined in detail.

Nonlinear piezoelectricity in CdTe

Physical Review B, 1993
Nonlinear piezoelectricity has recently been detected in strained-layer superlattices where CdTe is pseudomorphically grown along (111) on different materials. We investigate this problem from first principles using density-functional theory. As a byproduct, we provide the ab initio calculation of several properties of this material, including the ...

Chemical bevelling of CdTe and CdTe/MnTe structures

Materials Science and Engineering: B, 1998
Abstract We have developed an etching procedure based on 0.5 N-K 2 Cr 2 O 7 /H 2 SO 4 that enables the preparation of bevels with smooth surface and good profile linearity through CdTe and CdTe/MnTe structures. The bevel angles obtained are in the range of 10 −5 rad.

Growth and Characterization of CDTE and CDTE Alloys

MRS Proceedings, 1989
ABSTRACTMethods used to grow bulk, CdTe crystals, effects of alloying on their perfection and typical single crystal properties are reviewed in this paper. Crystals grown by a modified horizontal Bridgman technique have lower dislocation densities than those grown by a modified vertical Bridgman method.

Short period CdTe-ZnTe and CdTe-MnTe superlattices

Materials Science and Engineering: B, 1993
Abstract CdTe-ZnTe superlattices (SLs) with a period ranging from 13 to 38 A have been grown by atomic layer epitaxy (ALE) on (001) GaAs substrates. In a substrate temperature range between 270°C and 290°C the growth rate for both CdTe and ZnTe regulated itself to exactly 0.5 monolayers per reaction cycle, allowing the growth of very precisely ...

2014
The volt-current characteristics of n- and ??-type CdTe single crystals and polycrystals have been investigated. The effect of switching with memory after samples irradiation by laser pulses has been seen. The switching time is about 10???100 ns. It has been established that the apperance of switching effect with memory was motivated by the formation ...
