Cationic and Anionic Disorder in CZTSSe Kesterite Compounds: A Chemical Crystallography Study

Inorganic Chemistry, 2017
The cationic and anionic disorder in the Cu2ZnSnSe4-Cu2ZnSnS4 (CZTSe-CZTS) system has been investigated through a chemical crystallography approach including X-ray diffraction (in conventional and resonant setup), 119Sn and 77Se NMR spectroscopy, and high-resolution transmission electron microscopy (HRTEM) techniques.

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 ...

Inkjet-printed CZTSSe absorbers and influence of sodium on device performance

Solar Energy Materials and Solar Cells, 2018
Abstract Inkjet printing is a promising route for thin film deposition due to its low material wastage and potential of high throughput production. In this work, the inkjet printing technique is used for the deposition of Cu2ZnSn(SxSe1−x)4 (CZTSSe) thin films from Cu-Zn-Sn-S molecular inks.

Promoting effect of lanthanum doping on photovoltaic performance of CZTSSe solar cells

The Journal of Chemical Physics
A large open-circuit voltage (VOC) deficit is the major challenge hindering the efficiency improvement of Cu2ZnSn(S,Se)4 (CZTSSe) solar cells. Cation substitution, or doping, is usually an effective strategy to achieve carrier regulation and improve efficiency.

The Multiple Roles of Na Ions in Highly Efficient CZTSSe Solar Cells

Small
Abstract Sodium (Na) doping is a well‐established technique employed in chalcopyrite and kesterite solar cells. While various improvements can be achieved in crystalline quality, electrical properties, or defect passivation of the absorber materials by incorporating Na, a comprehensive demonstration of the desired

Crystallization Behavior of CZTSSe by Selenization of Sputtered CZTS Precursors

2014
In this work, we study the effect of annealing on crystallization behavior of Cu2ZnSn(SxSe1-x)4 (CZTSSe) absorbers. Cu-Zn-Sn-S precursors are deposited on glass/Mo substrate by cosputtering of Cu, ZnS, and SnS. In order to have a better understanding of the mechanisms of formation of CZTSSe and secondary phases during annealing, the effect of annealing
