7 Apr  Photodiodes are semiconductor light sensors that generate a current or voltage when the P-N junction in the semiconductor is illuminated by light. When a photon of sufficient energy strikes the diode, it excites an electron, thereby creating a free electron(and a. 25 Nov •A photodiode is a type of photo detector capable of converting light into either current or voltage •It converts light energy into electrical energy. pin Photodetector. The high electric field present in the depletion region causes photo-generated carriers to. Separate and be collected across the reverse. What does it detect? A photodiode array is good for visible and ultraviolet radiation. Dr. Prushan's Stolen Slides. merely the diode's reverse leakage current. Finally, the detector shunt resistance is the slope of the I-V curve. (dV/dI) evaluated at V= 0. Photodiode Operation. This article discusses what is a photodiode, working principle of photodiode, modes of operation, features, V-I characteristics and its applications.
