A schematic of a typical setup (taken from the ASTM E1021-15standard) is shown below. We start with a broadband light source, meaning one emitting a wide range of wavelengths. In order to not be as heavily influenced by dark current and give a more accurate snapshot of the device under its intended working conditions.

AI Customer ServiceA 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.
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. From this, you can calculate all the necessary device metrics needed to work out the efficiency of your solar cell. The I-V sweep is a quick measurement.
The measured values for voltage, current and temperature are recorded by separate and externally triggered calibrated multimeters. Both n- and p-type solar cells with edge lengths between 20 and 175mm and short-circuit currents of up to 15A are measured. Figure 2. CalTeC’s I–V curve measurement facility.
Most solar cell IV measurement software, such as the Ossila Solar Cell IV software, will ask you to input device active area. This means the output measurement is given as a JV curve from which device metrics can be easily worked out. Firstly, you must ensure the correct positioning of your testing system under your solar simulator.
For the calibration of a solar cell, the cell area, the spectral responsivity (SR) and the current–voltage (I–V) curve have to be determined. The I–V curve then yields the characteristic parameters, including the power conversion efficiency, fill factor, short-circuit current and open-circuit voltage.
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.
