Determining the Accuracy of Solar Cell and Module Measurements on High-Capacitance Devices

The accurate measurement of solar cells and modules is essential when characterizing these devices. High efficiency cells and modules are known to have capacitance effects that can compromise the accuracy of their measurements. As the cell designs in the photovoltaic industry trend towards higher efficiency (and higher capacitance) devices, assessing the accuracy of solar cell and module testers has become increasingly important. This paper will address the application of an analysis technique for assessing measurement errors when testing a range of solar cells and modules with varying amounts of capacitance.
