A J SC V OC curve1 is a valuable way of looking at an IV curve in the absence of series resistance. To trace a J SC V OC curve, the illumination on a cell is varied and the cell J SC and V OC measured at each illumination level. The series resistance has no effect on the V OC, since no current is drawn from the cell and so there is no voltage drop across the series resistance.
