I'm looking for the electrical and optical properties of Cadmium Sulphide.
Any links of info would be much appreciated

Cadmium Sulphide (CdS) is a compound made up of the elements cadmium and sulphur. It is a yellowish-orange solid that is commonly used in the production of semiconductors and solar cells.
Cadmium Sulphide is a semiconductor, meaning it has electrical conductivity between that of a metal and an insulator. It has a band gap of approximately 2.4 electron volts, making it useful for converting light energy into electrical energy.
Cadmium Sulphide has good optical properties, with a high refractive index and low optical absorption. This makes it useful for applications such as photocells and optical sensors.
Cadmium Sulphide is often used as a thin film layer in solar cells, where it acts as a window layer to allow light to pass through and reach the active layer. It can also be used as a buffer layer to improve the performance of the solar cell.
Cadmium Sulphide can be toxic if ingested or inhaled in large amounts. However, in its solid form it is relatively stable and does not pose a significant risk. Proper safety precautions should be taken when handling and disposing of CdS to avoid any potential health hazards.
