Photo emissive cell types

WebOct 12, 2015 · Photo-emissive Cell Requires an external power supply to facilitate flow of electrons. Amplifier circuits are employed for the amplification of the current. Three types; High vacuum Photo-emissive cell Gas-filled Photo cell Photomultiplier Tube (PMT) 45 45. High vacuum Photo-emissive cell 46 46. WebPhoto emissive cells have the most elaborative way of converting light into electricity. The cells are sealed in a vacuum tube made up of glass. Inside the tube, there is a big metal plate that behaves as a negative terminal or cathode with a smaller rod-like terminal which behaves as a positive terminal or anode.
