Solar cells convert light to electricity; radiometry is a very important facet of photovoltaic (PV) metrology. Radiometric measurements have the potential to introduce large errors in any given PV performance measurement because radiometric instrumentation and detectors can have total errors of up to 5% even with careful calibration.
A number of diagnostic measurements such as dark I–V and spectral response are widely used in photovoltaic research and development. Dark I–V shows how a device operates as a p-n junction and can be used to obtain series resistance, shunt resistance, and diode quality factor. Spectral response is a fundamental property of solar cells, and it can
However, the Nominal Operative Cell Temperature (NOCT) was the most suitable condition to test outdoor performance according to the manufacturer data. Therefore, this condition could be considered to evaluate the status of devices and to define the maintenance guidelines of photovoltaic devices. Finally, the NOCT behavior over time suggested that

Current–voltage (I–V) curve tracers are used for measuring voltage and current in photovoltaic (PV) modules. I–V curves allow identifying certain faults in the photovoltaic module, as well as quantifying the power performance of the device. I–V curve tracers are present in different topologies and configurations, by means of rheostats, capacitive loads, electronic
