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.
