Not in JEE Advanced syllabus

In the working of photodiode, the reverse current depends on

(A)concentration of majority carriers
(B)concentration of minority carriersCorrect
(C)applied voltage
(D)recombination of holes and electrons

Answer: (B)

Solution

A photodiode is operated in reverse bias. In reverse bias the majority carriers are pushed away from the junction, and the small reverse current is carried by minority carriers (electrons in the p-region and holes in the n-region) which are swept across the depletion region. When light falls on the junction, extra
