Cadmium Zinc Sulfide Sputtering Targets

Cadmium Zinc Sulfide Sputtering Targets

Cadmium zinc sulfide (CdZnS) sputtering targets are used in various advanced technology applications due to their unique optical and electronic properties. Here’s an overview of how CdZnS sputtering targets are employed in specific product applications.

Thin-Film Photovoltaic Cells

Application: CdZnS is used as a buffer or window layer in thin-film photovoltaic (solar) cells, especially in conjunction with cadmium telluride (CdTe) or other semiconductor materials.

Role: In solar cells, CdZnS acts as a buffer layer between the CdTe absorber layer and the transparent conductive oxide (TCO) layer. The buffer layer helps to optimize the electronic junction and improve the efficiency of the cell by enhancing the interface properties.

Optoelectronic Devices

Application: CdZnS is used in various optoelectronic devices, including light-emitting diodes (LEDs) and photodetectors.

Role: As a semiconductor material with tunable bandgap properties, CdZnS can be used to tailor the optical and electrical properties of devices. Sputtering targets deposit thin films of CdZnS that are essential for the functionality of these optoelectronic components.

Flat-Panel Displays

Application: CdZnS is used in the production of flat-panel displays, such as LCDs and OLEDs.

Role: In display technology, CdZnS thin films can be used as part of the electroluminescent layers or as a component of the display’s pixel structure. The material’s optical properties are leveraged to enhance the display’s performance.

 Luminescent Materials and Phosphors

Application: Used in luminescent materials and phosphors for lighting and display technologies.

Role: CdZnS can be used to create phosphors that emit light when excited by an external energy source. These materials are used in various lighting applications, including fluorescent lamps and other lighting devices.

 Semiconductor Layers in Sensors

Application: CdZnS is used in sensors for detecting various types of radiation or light.

Role: Thin films of CdZnS can be deposited onto sensor substrates to create layers with specific electronic and optical properties needed for the sensor’s operation.
