 Cadmium is a component of some compound semiconductors , such as cadmium sulfide , cadmium selenide , and cadmium telluride , used for light detection and solar cells . HgCdTe is sensitive to infrared light and can be used as an infrared detector , motion detector , or switch in remote control devices .
