Vedclass · Answer

(B) photodiode is a semiconductor device that converts light into electrical current. When light with energy greater than the bandgap energy of the semiconductor falls on the $p-n$ junction,electron-hole pairs are generated. The number of electron-hole pairs generated is directly proportional to the number of incident photons. Since the intensity of light is defined as the number of photons incident per unit area per unit time,the generated photocurrent (and the resulting $emf$ in open-circuit conditions) is directly proportional to the intensity of the incident light.

In a photodiode,the value of the $emf$ produced by a monochromatic light beam is directly proportional to
