What Does Photodiode Mean?
A photodiode is a device that helps in conversion of light into electric current. Made of semi-conductor material and containing a p-n junction, it is designed to function in reverse bias. Current is produced in the photodiode when photons are absorbed and a small amount of current is also produced when there is no light present. With increase of the surface area, photodiodes have slower response times. Photodiode technology has been successfully and widely used due to its simple and low-cost rugged structure.
