Influences of selenization temperature on the properties of CZTSSe thin films and CZTSSe/Mo interfaces

Journal of Materials Science: Materials in Electronics, 2021
Cu2ZnSn(S,Se)4 (CZTSSe) thin films were prepared on molybdenum foil substrate by sol–gel method. The effects of selenization temperature on the properties of CZTSSe thin films and CZTSSe/Mo interfaces were studied. The phase structures, elemental compositions, and morphologies of CZTSSe thin films and the morphologies and electrical properties of ...

CZTSSe Formation Mechanism Using a Cu/Zn/SnS Stacked Precursor: Origin of Triple CZTSSe Layer Formation

ACS Applied Materials & Interfaces, 2020
In this study, to control the formation of non-uniformly distributed large voids and Cu-Sn alloy agglomeration, which leads to local compositional misfit and secondary phase formation, a SnS compound precursor was applied instead of metal Sn to avoid compositional non-uniformity.

The effect of Rb doping on CZTSSe solar cells

Solar Energy, 2019
Abstract Alkali metal doping is a promising method to enhance the performance of Cu2ZnSn(Se,S)4 (CZTSSe) solar cells due to its excellent effect on Cu(In,Ga)Se2 (CIGS) solar cells. In this work, rubidium (Rb) was doped in CZTSSe absorbers by sputtering Rb doped Cu2ZnSnS4 (CZTS) target with subsequent H2Se contained annealing.

XPS study of CZTSSe monograin powders

Thin Solid Films, 2011
Abstract The surface and bulk composition of Cu2ZnSn(SexS1-x)4 (CZTSSe) monograin powders were investigated by X-ray photoelectron spectroscopy (XPS). The concentration depth profiling of CZTSSe monograin powders was obtained by Ar+ ion etching. According to the XPS spectra of CZTSSe monograin powder, the binding energies of Zn 2p3/2, Cu 2p3/2, Sn ...

Characterization of printed CZTSSe films for photovoltaic applications

SPIE Proceedings, 2013
Cu2ZnSn(S, Se)4 (CZTSSe) is a promising alternative absorber material for thin-film photovoltaic applications because of its earth-abundant constituents, tunable band gap, and high optical absorption coefficient. Using binary and ternary chalcogenide nanoparticles as precursors we have developed a chemical route to produce high efficiency CZTSSe ...

Grain growth of CZTSSe via nanocrystal selenization

2013 IEEE 39th Photovoltaic Specialists Conference (PVSC), 2013
Achieving micro-sized and closed packed grains is an essential requirement for high performance chalcogenide thin film solar cells. The grain growth mechanism of CZTSSe starting from nanocrystal films appears to be affected by the capping ligands composed of long hydrocarbon chains.

CZTSe devices fabricated from CZTSSe nanoparticles

2013 IEEE 39th Photovoltaic Specialists Conference (PVSC), 2013
To understand and control the growth paths of kesterite based CZTSe films as prepared from kesterite nanoparticles we investigate films prepared from different chalcogenide ratios in the initial nanoparticles. To do so we introduce a new method for producing kesterite nanocrystals with controlled ratios of sulfur and selenium.

Synthesis and characterization of CZTSSe nanoparticle inks for photovoltaic devices

physica status solidi c, 2015
AbstractCu2ZnSnSe4 (CZTSe) is one of the promising materials as absorber layers in thin film solar cells. It contains earth abundant and non‐toxic elements. With a broad optical band gap at 1.5 eV as well as a high absorbance coefficient of 10–4 cm–1, CZTS is also a good light harvesting material.
