Hence, to find out what the voltage does under illumination, we need to have a look at how the photogeneration of electrons and holes acts on the quasi-Fermi energy.

In order to measure the voltage-current characteristics of a solar cell under illumination, typically the SMU is stepped through various current limiting levels and the corresponding voltages are measured.

Now, we are going to modify this equation because we want to find how the open circuit voltage at concentrated light would be related to the open circuit voltage at ambient light.

To be more accurate, a typical open circuit voltage of a solar cell is 0.58 volts (at 77°F or 25°C). All the PV cells in all solar panels have the same 0.58V voltage. Because we connect them in series, the
