I/V Curve

Definition: It a graphic tool to evaluate a electronic circuit element where the current is plotted on the Y vertical axis and voltage is plotted on the X horizontal axis.

In practice:

  • I/V current of a diode tells us when the diode conducts in the forward biased region. In addition, in the reverse biased diode case, the I/V current tells us when the diode breaks down.
  • I/V curve of a solar cell tells us the rated operation characteristics in terms o f open circuit voltage and short circuit current when a light is illuminated on the solar cell
