What are photoelectric cells?
Photoelectric cells are devices that generate electrical output that is dependent on the amount of illumination. They are used in various mechanical devices to set off alarms or open doors.

Give two examples of photoelectric cells and explain how they work?
The most common photoelectric cells consist of two electrodes separated by light sensitive semiconductor material. A high voltage source, such as a battery, is connected to the electrodes set up a current even in the absence of light. When light strikes the semiconductor material in the photocell, current in the circuit increases in proportion to the intensity of the light. The current from a photoelectric cell is often used to operate switches or relays, so are often used in automatic door openers and intrusion alarms. This type of photoelectric cells are called electric eyes.
