An I/V (Current-Voltage) curve is a graphical tool used to evaluate electronic circuit elements, where the current is plotted on the vertical Y-axis and the voltage is plotted on the horizontal X-axis.
The I/V curve of a diode provides insights into its behavior in different biasing conditions. In the forward-biased region, the I/V curve shows when the diode begins to conduct current. On the other hand, in the reverse-biased region, the I/V curve indicates the breakdown point of the diode.
For a solar cell, the I/V curve illustrates its operational characteristics under illumination. It reveals important parameters such as the open circuit voltage (Voc) and short circuit current (Isc), providing a measure of the cell's performance in generating electricity when exposed to light.
