For example, IEC61215 or IEC61730 are the standard test procedures used to measure the solar panel quality in the manufacturing industry [45]. EBIC is a powerful PV defect detection instrument whereby an electron-hole pair is created on the PV cell surface to measure its carrier collection efficiency [135].
The diode quality factor of crystalline silicon solar cells does not appear to change appreciably (e.g. Breitenstein, 2013, Khan et al., 2010) under typical operating outdoor conditions. Even if we assume that the diode quality factor is irradiance dependent, then we may conduct measurements at M different irradiance levels.

Accurate characterization of solar / photovoltaic cells requires the combined capabilities of a current source, a voltage source, a current meter, and a voltage meter. Necessary measurements for solar cells include IV parameters and characteristics, including short circuit current, open circuit voltage, and maximum power point.
A Kelvin or four-wire measurement is essential to getting accurate IV data while testing a solar cell. A variable load is applied across the four wires in order to get a variety of current and voltage measurements for the device under test. Exactly what current and voltage is unknown until tested, which is why there is some iteration needed.
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.
Pulsed measurements are crucial for testing solar cells to prevent device self-heating from distorting the measurement results. Solar cell measurement typically requires 4-wire measurements (remote sensing) to eliminate the voltage error caused by test lead residual resistance.
