N/Type Cadmium Telluride
Specially used for making thin film solar cells & electro-optic modulators
1. Santech Materials specializes in producing CdTe powder/target (99.99% - 99.99999%) in vacuum equipment with inert
2. Cadmium telluride (CdTe) is a stable crystalline compound formed from cadmium and tellurium. It is used as an
infrared optical window and is a highly efficient solar cell material with lowest-cost types of solar cell.
3. More detail specification can be learnt downloaded from http://www.santechchem.com/ or sent to you upon request.
