SunsVoc
SunsVOC measurements 12 are very similar to the JSC VOC measurements except that the SunsVOC uses a separate solar cell to monitor the illumination intensity rather than using the JSC of the solar cell. The monitor cell simplifies the measurement electronics since measuring cell voltage is much simpler than measuring the cell current. By using a flash lamp with a slow decay a SunsVOC can be taken very quickly and simply.
The SunsVOC measurement provides the IV curve of the diode without the effects of series resistance. Fitting to the SunsVOC curve is easier than to the dark or illuminated curves since there is no Rs.
