There are several methods used to characterize solar cells. The most common and essential measurement you can take is the current-voltage (I-V) sweep.

The relationship between the two might need to be adjusted for the resistances of the wires, as in the example we described above, but overall the four-wire measurement is a way to accurately get current and voltage information of a device. A Kelvin or four-wire measurement is essential to getting accurate IV data while testing a solar cell.
There are three metrics which will determine solar cell efficiency: the open circuit voltage (V OC), the short circuit current (J SC), and the fill factor (FF). When measuring solar cells, we often refer to current density, J, rather than just current, I. This allows researchers to compare devices with different active areas.
A four-quadrant power supply is used for the measurement of the solar cell I–V curve. The current is measured by means of a voltage measurement across calibrated high-power precision shunt resistors. The measured values for voltage, current and temperature are recorded by separate and externally triggered calibrated multimeters.
Of coruse, you could use actual sunlight, but this would introduce an uncontrollable variable. To test solar cells reliably, you need to maintain controlled conditions within your lab — and this is impossible to do while allowing direct, unfiltered sunlight onto your testing equipment.
