I-V Curve of Solar Cells – Definition, Glossary, Details – Solar Mango

IV curve or Current-Voltage curve of a solar cell/panel shows the possible combinations of current and voltage output of a photovoltaic (PV) device. It is a graph that plots the current versus the voltage from the PV device as the electrical load (or resistance) is increased from short circuit (no load) to open circuit (maximum voltage). The shape of the curve characterizing cell performance. Three important points on the I-V curve are the open-circuit voltage (Voc), short-circuit current (Isc), and peak or maximum power (operating) point (Pmp).
