IV Curve

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. Illuminating a cell adds to the normal "dark" currents in the diode so that the diode law becomes:

The current-voltage (I-V) curve for a PV cell shows that the current is essentially constant over a range of output voltages for a specified amount of incident light energy. Figure 1: Typical I-V Characteristic Curve for a PV Cell Figure 1 shows a typical I-V curve for which the short-circuit output current, ISC is 2 A.

The output power of the PV cell is voltage times current, so there is no output power for a short-circuit condition because of VOUT or for an open.

The efficiencyof a PV cell is the ratio of light energy falling on the cell to the light energy that is converted into electrical energy. It is expressed as a percentage, as shown in the following.

The fill factor of a PV cell is an important parameter in evaluating its performance because it provides a measure of how close a PV cell comes to providing its maximum theoretical output power. The fill factor (FF) is the ratio of.

Several factors determine the efficiency of a PV cell: the type of cell, the reflectance efficiency of the cell’s surface, the thermodynamic efficiency limit, the quantum efficiency, the maximum power point, and internal.The I–V curve serves as an effective representation of the inherent nonlinear characteristics describing typical photovoltaic (PV) panels, which are essential for achieving sustainable energy systems.
