A method to improve crystal quality of CZTSSe absorber layer

Journal of Sol-Gel Science and Technology, 2018
In this work, a fabrication process of high crystallinity CZTSSe absorber layer is presented. The CZTS structure is firstly prepared by spin-coating method then the film is converted into CZTSSe via selenization process using graphite box and tube furnace. Se powder has been used as source of selenizing vapors.

Impact of Lithium as Interfacial Treatment for CZTSSe Solar Cells

2024 IEEE 52nd Photovoltaic Specialist Conference (PVSC)
Cu2ZnSn(S,Se)4 (CZTSSe), despite its slow progress in terms of efficiency, stands out as a viable option for solar cell absorber materials due to its comparatively low-cost fabrication process, and abundance of constituent elements. The efficiency of CZTSSe faces challenges, particularly a notable Voc deficit arising from its non-stoichiometric nature ...

Fabrication of 7.2% Efficient CZTSSe Solar Cells Using CZTS Nanocrystals

Journal of the American Chemical Society, 2010
Earth abundant copper-zinc-tin-chalcogenide (CZTSSe) is an important class of material for the development of low cost and sustainable thin film solar cells. The fabrication of CZTSSe solar cells by selenization of CZTS nanocrystals is presented. By tuning the composition of the CZTS nanocrystals and developing a robust film coating method, a total ...

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.

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
