Physics - Semiconductors Question with Solution | TestHub

The $I-V$ curve for solar cell is available in the fourth quadrant, i.e. where current is negative, which means that current $I$ is supplied by the solar cell and not drawn by it.

In the given figure, the point where the graph touches the $x-$axis shows the open circuit voltage while the point where it touches the $y-$axis shows the short circuit current.
