Tailoring Mo(S,Se)2 structure for high efficient Cu2ZnSn(S,Se)4 solar cells
Solar Energy Materials and Solar Cells, 2018Abstract The direction of Se-Mo-Se sheets to the Mo film is crucial for the thickness of Mo(S,Se)2 and the electrical conductivity, so as the back contact of Cu2ZnSn(S,Se)4 solar cells. In this study, the preferred orientation of Mo(S,Se)2 film changes from (100) peak to (103) peak, i.e.

Enhanced photoresponse of Cu2ZnSn(S, Se)4 based photodetector in visible range
Journal of Alloys and Compounds, 2017Abstract Fast switching response of photodetectors is needed for many applications. Therefore, it is necessary to study the photoconductivity properties of earth abundant and cost effective materials. Till now, there are only two reports based on photoconductivity study of Cu 2 ZnSnS 4 ( CZTS) based materials.

Modification of crystallization in Cu2ZnSn(S,Se)4 films using Al2O3 capping layers
Solar Energy Materials and Solar Cells, 2021Abstract In this paper, we reported a modified preparation process for Cu2ZnSn(S,Se)4 (CZTSSe) films. For this process, Al2O3 capping layers were deposited on precursor films before selenization. It was found the capping layer can prevent the formation of separate CuxSe phase on top of the film and facilitate a homogeneous growth of the crystalline ...

Electronic and elemental properties of the Cu2ZnSn(S,Se)4 surface and grain boundaries
Applied Physics Letters, 2014X-ray and femtosecond UV photoelectron spectroscopy, secondary ion mass spectrometry and photoluminescence imaging were used to investigate the electronic and elemental properties of the CZTS,Se surface and its oxides. Oxide removal reveals a very Cu poor and Zn rich surface relative to bulk composition.

Effect of germanium incorporation on the properties of kesterite Cu2ZnSn(S,Se)4 monograins
Thin Solid Films, 2019Abstract In this work, the influence of partial substitution (up to 10%) of tin (Sn) by germanium (Ge) in Cu2ZnSn(S,Se)4 (CZTSSe) solid solution monograins was studied. The external quantum efficiency measurements of the CZTGSSe monograin layer solar cells showed an increase in the band gap energy of the Ge-substituted CZTGSSe.

Precursor designs for Cu2ZnSn(S,Se)4 thin-film solar cells
Nano Energy, 2017Abstract To commercialize Cu2ZnSn(S,Se)4 (CZTSSe) thin-film solar cells, it is necessary to improve their efficiency and to develop the technological ability to produce large-area modules. Defect formation due to the secondary phase is considered to be one of the main reasons for decreased CZTSSe thin-film solar-cell efficiency.
