The Copper Zinc Tin Sulfide Selenide Target (CZTSSe) is a versatile quaternary semiconductor material celebrated for its adjustable bandgap, high optical absorption, and the use of earth-abundant elements. This makes CZTSSe an environmentally friendly and cost-effective alternative to conventional photovoltaic materials. As a sputtering target, CZTSSe ensures uniform chemical and structural properties, facilitating precise thin-film deposition with controlled stoichiometry.
By varying the ratio of sulfur to selenium, the bandgap of CZTSSe can be finely adjusted between 1.0 to 1.5 eV, optimizing solar energy conversion efficiency. Its high absorption coefficient (>10⁴ cm⁻¹) allows for the creation of thin yet highly efficient absorber layers. The target is manufactured with enhanced density and minimal porosity through techniques such as hot pressing or spark plasma sintering, which improve sputtering efficiency and ensure uniform film deposition. Additionally, CZTSSe is compatible with both vacuum and non-vacuum deposition methods and resists phase segregation during processing, making it ideal for scalable production of next-generation thin-film solar cells.
Our CZTSSe Targets are meticulously packaged to ensure their integrity during transit and storage. Depending on the size, smaller targets are securely placed in polypropylene (PP) boxes, while larger targets are shipped in custom-designed wooden crates. We prioritize customized packaging solutions, employing appropriate cushioning materials to provide maximum protection.
Packaging Options:
Q1: What is the primary advantage of using a CZTSSe sputtering target?
A1: CZTSSe comprises earth-abundant, non-toxic elements, making it a cost-effective and environmentally friendly alternative to traditional thin-film materials like CIGS.
Q2: Which deposition methods are compatible with CZTSSe targets?
A2: CZTSSe targets are suitable for use in both RF and DC magnetron sputtering systems. They can also be paired with post-deposition selenization or annealing processes to achieve the desired phase and crystallinity.
Q3: How is film quality maintained during deposition?
A3: Film quality is controlled by optimizing parameters such as substrate temperature, sputtering power, chamber pressure, and post-deposition annealing to prevent the formation of secondary phases.
