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.
Accurate characterization of solar / photovoltaic cells requires the combined capabilities of a current source, a voltage source, a current meter, and a voltage meter. Necessary measurements for solar cells include IV parameters and characteristics, including short circuit current, open circuit voltage, and maximum power point.
Nevertheless, review papers proposed in the literature need to provide a comprehensive review or investigation of all the existing data analysis methods for PV system defect detection, including imaging-based and electrical testing techniques with greater granularity of each category's different types of techniques.
Abstract. By testing the I-V characteristics of the solar photovoltaic cell array and referencing the experimental data, it can effectively evaluate the PV power plant control and design standards.
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.
However, the integrity of solar photovoltaic (PV) cells can degrade over time, necessitating non-destructive testing and evaluation (NDT-NDE) for quality control during production and in-service inspection. Hyperspectral (HS) imaging has emerged as a promising technique for defect identification in PV cells based on their spectral signatures.
