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.
Basic operation of a solar cell. a) A photon is absorbed by the semiconductor, b) an electron is promoted from the valence band to the conduction band, leaving a hole in the valence band. c) The electron and hole are transported to electrodes to be collected.
However, a much more practical method is to measure the current and voltage response of the device under broadband light, which removes the need to manually integrate (sum) all the individual pieces. IEC 60904-1 specifies the standard procedure for measuring current and voltage characteristics of photovoltaic devices.
The primary characteristics of a solar cell can be determined by using an I-V curve to examine the relationship between the current and voltage produced. Current level is determined by the intensity of solar radiation on the cell, while an increase in the cell’s temperature reduces its voltage. Solar cells produce DC electricity (direct current).
