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
The I–V curve of a PV cell is shown in Figure 6. The star indicates the maximum power point (MPP) of the I–V curve, where the PV will produce its maximum power. At voltages below the MPP, the current is a relative constant as voltage changes such that it acts similar to a current source.
Other important characteristics include how the current varies as a function of the output voltage and as a function of light intensity or irradiance. 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.
This section will introduce and detail the basic characteristics and operating principles of crystalline silicon PV cells as some considerations for designing systems using PV cells.
