Typically a solar or photovoltaic cell has negative front contact and positive back contact. A semiconductor p-n junction is in the middle of these two contacts like a battery. If these two sides are connected by an external circuit, current will start flowing from positive to negative terminal of the solar cell.

The IV curve of a solar cell is the superposition of the IV curve of the solar cell diode in the dark with the light-generated current.1 The light has the effect of shifting the IV curve down into the fourth quadrant where power can be extracted from the diode.

The main points of the I-V and P-V curves characteristics are the short-circuit current ( ) or the maximum current at zero voltage, and the open-circuit voltage ( ) or the maximum voltage at zero current.

EXPERIMENT: To plot the V-I Characteristics of the solar cell and hence determine the fill factor. ... Fig. ... energy create hole-electrons pairs. ... ∴ Ideal Power = VOC × ISC. The maximum useful power is the area of the largest rectangle that can be formed under the V-I. ... ∴ Fill factor =

An I-V curve (short for 'current-voltage characteristic curve'), is a graphical representation of the relationship between the voltage applied across an electrical device and the current flowing through it. It is one of the most common methods of determining how an electrical device functions in a circuit.

Solar Cell I-V Characteristic Curves are graphs of output voltage versus current for different levels of insolation and temperature and can tell you a lot about a PV cell or panel's ability to convert sunlight into electricity.
