Selenium.<\/p>\n<p>A photoconductive cell is a device that converts light into an electrical signal. It is made up of a thin layer of selenium, which is a semiconductor. When light hits the selenium, it causes electrons to be released from the atoms. These electrons are then collected by an electrode, which creates an electrical current.<\/p>\n<p>Quartz is an insulator, so it cannot be used in a photoconductive cell.
