A photodiode is operated in the reverse bias. Why? - BYJU

WebOct 5, 2024 · A photodiode is just like a regular semiconductor diode (example 1N4148) consisting of a p-n junction, but it has this junction exposed to light through a transparent body. Its working can be understood by imagining a standard silicon diode connected in reverse biased fashion across a supply source as shown below. A photodiode is designed to operate in reverse bias. A solar cell used to generate electric solar power is a large area photodiode. Photodiodes are used in scientific and industrial instruments to measure light intensity, either for its own sake or as a measure of some other property (density of smoke, for example).
