Question

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

Which of the followinng 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 point $A$ and $B$ represent open circuit voltage and current, respectively
• C. It is for photodiode and points $A$ and $B$ represent open circuit voltage and current respectively.
• D. It is for a LED and points $A$ and $B$ represnet open circuit volatage and short circuit current, respectively.

Answer 1

The correct option is A It is $V-I$ characteristic for solar cell where, point $A$ represents open circuit voltage and point $B$ short circuit current.

For a Solar cell
$\to$ Open circuit $I=0$, potential $V=\text{emf}$
$\to$ Short circuit $I=I$, potential $V=0$

It is $V-I$ characteristic for solar cell where, point $A$ represents open circuit voltage and point $B$ short circuit current.
