Description
This report presents the results of an international intercomparison of photovoltaic (PV) performance measurements and calibrations that took place from 1993 to 1997. The intercomparison, which was organized and operated by a group of representatives from national PV measurements laboratories, was accomplished by circulating two sample sets. One set, consisting of 20 silicon reference cells, was intended to form the basis of an international PV reference scale. A qualification procedure applied to the calibration results gave average calibration numbers with an overall standard deviation of less than 2% for the entire set. The second sample set was assembled from a wide range of newer technologies that present unique problems for PV measurements. As might be expected, these results showed much greater differences among the laboratories. Methods were then identified that should be used to measure such devices, along with problems to avoid. The report concludes with recommendations for future intercomparisons.
