Suns-Voc Applications


By either probing the silicon p+ and n+ regions directly or probing the metallization layer (if present), the illumination-Voc curve can be measured. This curve can be displayed as our well-known Suns-Voc plot or in the form of a standard photovoltaic curve which can be used to characterize shunting. The entire curve is measured at the open-circuit voltage, so it is free from the effects of series resistance. Comparing this curve to the final I-V curve gives a precise measure of the series resistance in the cel
