A LIGHT EMITTING DIODE (LED) CAN OPERATE IN REVERSE AS A LIGHT SENSOR.
WHEN EXPOSED TO LIGHT WHILE REVERSE-BIASED, IT GENERATES A SMALL
PHOTOCURRENT, AND IT CAN EVEN PRODUCE A TINY VOLTAGE WHEN ILLUMINATED
WITHOUT ANY EXTERNAL POWER, ESSENTIALLY FUNCTIONING AS A MINIATURE
SOLAR CELL. THIS PROPERTY IS OCCASIONALLY EXPLOITED IN LOW-COST
BIDIRECTIONAL COMMUNICATION SYSTEMS WHERE THE SAME LED SERVES AS BOTH
A TRANSMITTER AND A RECEIVER.
