Photocells are semiconductors that are light detectors.
Photocells have many uses, especially as switches and sensors. Automatic lights that turn on when it gets dark use photocells, as well as streetlights that switch on and off according to whether it is night or day.
Photocells are highly effective in automating security lights so that they turn on when it gets dark and off when it’s day time.
