I-V characteristics of solar cell is drawn in the fourth quadrant. The reason is

Solar cells does not draw current and supplies the same to the load. Solar cell draws the current and does not supply. Solar cell does not supply the current. Solar cell only store the light energy.

Solar cells does not draw current and supplies the same to the load.

The $V-I$ 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.
