19. A PV cell is a light illuminated pn- junction diode which directly converts solar energy into electricity via the photovoltaic effect. A typical silicon PV cell is composed of a thin wafer consisting of an ultra-thin layer of phosphorus-doped (n-type) silicon on top of a thicker layer of boron- doped (p-type) silicon. When sunlight strikes the surface of a PV cell, photons

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.
We are proud to house and manage one of the few commercial photovoltaic and calibration test laboratories in the world. The PV Calibration Lab uses state of the art equipment, including the Oriel Class AAA 8x8 inch Sol3A solar simulator and Oriel Quantum Efficiency Systems, in order to provide record-setting certifications for photovoltaic cells.
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 reference cell is a recommended option. It includes a calibrated reference solar test cell and a digital display, showing real-time values of the measured solar simulator irradiance and the cell temperature. These values are entered in the software to perform the I-V characterization.
The Photovoltaic Calibration and Test Laboratory is accredited by A2LA to the ISO/IEC 17025 Standard, using state of the art equipment for measurements in accordance with ASTM E948 and E1021. The lab welcomes requests for prototype PV device performance measurements or PV reference cell calibrations.
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.
