The given graph represents V-I characteristic for a semiconductor device. Which of the following statement is correct? (a) It is V-I characteristic for solar cell where, point A represents open circuit voltage and point B short circuit current. (b) It is for a solar cell and popints A and B represent open circuit voltage and current, respectively. (c) It is for a photodiode and points A and B represent open circuit voltage and current, respectively. (d) It is for a LED and points A and B represent open circuit voltage and short circuit current, respectively.

Answer: (a). The curve lies in the fourth quadrant, which is the V-I curve of a solar cell. At A the current is zero, so the voltage there is the open circuit voltage Voc. At B the voltage is zero, so the current there is the short circuit current Isc. So the answer is (a).

The given graph represents V-I characteristic for a semiconductor device.

Which of the following statement is correct?

Show answer and solution

Answer: (a)

The curve lies in the fourth quadrant, which is the V-I curve of a solar cell.
At A the current is zero, so the voltage there is the open circuit voltage $V_{oc}$ .
At B the voltage is zero, so the current there is the short circuit current $I_{sc}$ .
So the answer is (a).
