Overview

Photodiodes make use of the photovoltaic effect – the generation of a voltage across a P-N junction of a semiconductor when the junction is exposed to light. While the term photodiode can be broadly defined to include even solar batteries, it usually refers to sensors intended to detect the intensity of light. They are widely used for the detection of the existence, intensity, position and color of light. When a voltage is applied to a photodiode in the dark state, the V-I characteristic curve observed is similar to the curve of a conventional rectifier diode. However when light strikes the photodiode, the curve shifts as shown and, increasing the amount of incident light shifts the characteristic curve further in parallel with respect to incident light intensity
