Reduction of interface recombination current for higher performance of p+-CZTSxSe(1-x)/p-CZTS/n-CdS thin-film solar cells using Kesterite intermediate layers

, 2020
There have been significant efforts to enhance the performance of CZTS thin-film solar cells. However, the increase in series resistance, formation of the unfavorable MoS2 between the absorber layer and back-contact, and recombination losses are some of ...

The CZT X-ray Imager on AXO

Astrophysics and Space Science, 2001
DSRI has initiated a development program of CZT X-ray and gamma ray detectors employing strip readout techniques. A dramatic improvement of the energy response was found operating the detectors as so-called drift detectors. For the electronic readout, modern ASIC chips were investigated. Modular design and the low power electronics will make large area

CZTS solar cell with non-toxic buffer layer: A study on the sulphurization temperature and absorber layer thickness

, 2020
Cu2ZnSnS4 solar cell has been fabricated with a non-toxic buffer layer and Al doped ZnO transparent conducting layer. A detailed material study on each layer of the solar cell has been carried out independently.

CZTS Monograin Powders and Thin Films

Advanced Materials Research, 2011
This paper reviews results of studies on different materials and technologies for polycrystalline solar cells conducted at Tallinn University of Technology. Structural properties and defect structure of kesterite CZTS compounds (Cu2ZnSnSe4, Cu2ZnSn(SSe)4) were studied.

Modelling of CZT strip detectors

AIP Conference Proceedings, 2000
Position-sensitive CZT detectors for astrophysical research in the five-several hundred keV range are being developed at UCSD and WU. These can be used for large area detector arrays in coded mask imagers and small-area focal plane detectors for focusing X-ray telescopes.

Excited-State Dynamics in CZTS Nanocrystals

The Journal of Physical Chemistry Letters, 2013
Ultrafast dynamics of conduction-band electrons in stoichiometric Cu2ZnSnS4 nanocrystals are investigated using pump–probe spectroscopy. The nanocrystal samples minimize nonstoichiometric defects that can serve as electron traps, allowing for investigation of the native dynamics of the initially prepared excited states.

CZT Support for Z Extensions

2005
Community Z Tools (CZT) is an integrated framework for the Z formal specification language. In this paper, we show how it is also designed to support extensions of Z, in a way that minimises the work required to build a new Z extension. The goals of the framework are to maximise extensibility and reuse, and minimise code duplication and maintenance ...
