Comparative study between CZTS and CZTSe thin layers for photovoltaic applications [PDF]

E3S Web of Conferences, 2023
A comparative study of the thin layer based on copper zinc tin sulphide Cu2ZnSnS4 (CZTS) and that based on copper zinc tin selenide Cu2ZnSnSe4 (CZTSe) was made in order to assess the structural, morphological, optical and electrical qualities. for better

Deposition of CZTSe thin films and illumination effects on the device properties of Ag/n-Si/p-CZTSe/In heterostructure [PDF]

Journal of Alloys and Compounds, 2017
Abstract Characterization of Cu 2 ZnSnSe 4 (CZTSe) thin films deposited by thermal evaporation sequentially from the pure elemental sources and in-situ post annealing was carried out at 400 C under Se evaporation atmosphere. Another annealing process was applied in nitrogen atmosphere at 450 °C to get polycrystalline monophase CZTSe film structure ...

THE EFFECT OF ANNEALING PRESSURE AND TIME ON THE CRYSTALLINITY OF CZTSe [PDF]

Surface Review and Letters, 2019
In this study, the effect of annealing pressure and time on the homogeneity and the formation of kesternite (Cu2ZnSnSe4; CZTSe) structure was investigated. The deposition of CZTSe coating was carried out using an electroplating method. The morphology and crystal structure of the coating were investigated using SEM–EDS, XRD and Raman spectroscopy ...

Overcoming the V_oc limitation of CZTSe solar cells

2016 IEEE 43rd Photovoltaic Specialists Conference (PVSC), 2016
The V oc deficit issue is considered to be the most significant limitation of high-performance kesterite devices [1]. Secondary phases, defects, band tailing and interface recombination at the kesterite/CdS heterojunction are possible reasons for the low V oc .

Modifications of the CZTSe/Mo back-contact interface by plasma treatments [PDF]

RSC Advances, 2019
Molybdenum (Mo) is the most commonly used back-contact material for copper zinc tin selenide (CZTSe)-based thin-film solar cells. The effect of a pure Ar plasma and a mixed Ar–N2 plasma on the back-contact interface of CZTSe solar cells is reported in this study.

The structure, phase and chemical composition of CZTSe thin films [PDF]

Functional Materials, 2014
Cu???ZnSnSe??? thin films obtained by co-evaporation of components using an electron beam evaporation system were investigated by scanning electron microscopy, X-ray analysis, PIXI and RBS methods. The analysis of the diffraction patterns showed that the films are almost single-phased and contain mainly CZTSe compound, which has a tetragonal kesterite ...
