Results of the PEP '93 Intercomparison of Reference Cell Calibrations and the Newer Technology Performance Measurements

    Research output: Contribution to conferencePaper

    Abstract

    This document presents the results of an international intercomparison of photovoltaic (PV) performance measurements and calibrations. The intercomparison, which was organized and operated by a group of experts representing national laboratories from across the globe, was accomplished by circulating two sample sets. One set consisted of twenty silicon reference cells that would, hopefully, formthe 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 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 largerdifferences among laboratories. Methods were then identified that should be used to measure such devices, along with problems to avoid.
