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.
Germany-based Wavelabs Solar Metrology Systems GmbH has released two new solar simulators for high-efficiency cell testing, one for use in production lines, and the other for use in research laboratories.
It is made to test high-efficiency solar cell technologies, such as passivated emitter rear contact (PERC), heterojunction (HJT), and tunnel oxide passivated contact (TOPCon). The size of the illumination area is 260 mm x 260 mm, which means it can accommodate the newer, larger cell sizes.
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.
