The photosensitive diode is also called photoelectric diode, it has the same structure with the general semiconductor diode. The figure shows the structure of the photosensitive diode. There is a glass lens on the photodiode shell, the incident light is shining on the tube core through the glass lens. The tube core of the light-emitting diode is the PN junction with the photosensitive properties, it is packaged in the tube shell. The photosensitive surface of the light-emitting diode is the film of the N-type silicon. The PN junction of the light-emitting diode's core and the core itself have large area, but the electrode area of the tube core is small.
