Photodiodes, also known as photocells, are electronic detectors that convert light into electrical current. They are used for a wide range of applications including light sensing, optical switches, and digital imaging. Photodiodes consist of a semiconductor junction that emits electrons when exposed to light. The current they generate is proportional to the intensity of the light, and can be used to detect the presence of light or measure its intensity.
