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.

Suppressing Element Inhomogeneity Enables 14.9% Efficiency CZTSSe Solar Cells

Advanced Materials
AbstractKesterites, Cu2ZnSn(SxSe1−x)4 (CZTSSe), solar cells suffer from severe open‐circuit voltage (VOC) loss due to the numerous secondary phases and defects. The prevailing notion attributes this issue to Sn‐loss during the selenization. However, this work unveils that, instead of Sn‐loss, elemental inhomogeneity caused by Cu‐directional diffusion ...

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.

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 ...
