Effect of Cu–Sn–Se Liquid Phase on Grain Growth and Efficiency of CZTSSe Solar Cells
Advanced Energy Materials, 2020 Herein, a liquid-assisted grain growth (LGG) mechanism for a vacuum-processed Cu2ZnSn(S1− xSex)4 (CZTSSe) absorber that is enabled by the presence of a liquid phase containing predominantly Cu, Sn, and Se (L-CTSe) is suggested to explain the large grain ...

The effect of Rb doping on CZTSSe solar cells
Solar Energy, 2019Abstract 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, 2011Abstract 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 ...

Grain growth of CZTSSe via nanocrystal selenization
2013 IEEE 39th Photovoltaic Specialists Conference (PVSC), 2013Achieving 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.

Characterization of printed CZTSSe films for photovoltaic applications
SPIE Proceedings, 2013Cu2ZnSn(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 ...
