  1. Photoelectric cells are used in obtaining electric energy from sunlight.
  2. Photoelectric cells are used in exposure meter.
# The exposure meter in used along with a camera to know the correct time of exposure for having a good picture.
  1. They are used in lux-meter. It is use to determine the intensity of light.
  2. A photoelectric cell is also used in industries to locate the flaws in the metal sheet.
  3. A photoelectric cell, whose cathode is coated with lead sulphide, is sensitive to infra-red-light. Such a photoelectric cell is used in electronic ignition circuit.
  4. They are used in robotics, wherever to direct the robots to hide from view in the dark, otherwise to follow a beacon or line.
  5. Photoelectric cells are used instead of photovoltaic cells and variable resistors.
