Standards, Calibration, and Testing of PV Modules and Solar Cells

Because solar cells convert light to electricity, radiometry is a very important facet of 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 [11], [12].Other errors can be introduced …
