Special Purpose Diodes

Consider the following statements A and B and identify the correct answer:

Figure

A. For a solar-cell, the I-V characteristics lies in the IV quadrant of the given graph. B. In a reverse biased pnpn junction diode, the current measured in (μA)(\mu\text{A}), is due to majority charge carriers.

Show answer and solution

Answer: (a)

  1. A: a solar cell gives power, so V>0V > 0 while current flows opposite to forward current (I<0I < 0). Its curve lies in quadrant IV. A is correct.
  2. B: the small reverse current (μ\muA) is due to minority carriers, not majority carriers. B is incorrect.
  3. So the answer is (a) A is correct but B is incorrect.
