Phototube
Phototubes operate according to the photoelectric effect: Incoming photons strike a photocathode, knocking electrons out of its surface, which are attracted to an anode.Thus current is dependent on the frequency and intensity of incoming photons. Unlike photomultiplier tubes, no amplification takes place, so the current through the device is …
How do photoelectric cells work?
All these things are examples of photoelectric cells (sometimes called photocells)—electronic devices that generate electricity when light falls on them. What are they and how do they work? Let''s take …
