What is the principle behind a photodiode? (2022)
  • Step 1: Understand that a photodiode is a device that detects light.
  • Step 2: Learn about the photoelectric effect, which is the process where light hits a material and causes it to release electrons.
  • Step 3: When light hits the photodiode, it generates pairs of electrons and holes (the absence of electrons).
  • Step 4: The movement of these electrons and holes creates an electric current.
  • Step 5: This electric current can be measured and is used to determine the intensity of the light.
