The series resistance of a solar cell dominates fill factor losses, especially in large area commercial solar cells, so an accurate measurement is vital in quantifying losses. There are several methods to measure series resistance and the comparisons of the accuracy for specific cell types. 1 2
Series and shunt resistances in solar cells are parasitic parameters, which affect the illuminated current–voltage (I–V) characteristics and effi ciency of cells. Very high values of series resistance (R s) and very low values of shunt resistance (R sh) reduce short-circuit current density (J sc) and open-circuit voltage (V oc), respectively.
Series resistance does not affect the solar cell at open-circuit voltage since the overall current flow through the solar cell, and therefore through the series resistance is zero. However, near the open-circuit voltage, the IV curve is strongly affected by the series resistance.
An inversion of this method permits an easy determination of the series resistance, involving measurements at two arbitrary light levels of unknown magnitude. The effects of series resistance consist at high light levels in a flattening of the photovoltaic output characteristic and a related drop in the maximum power point voltage.
However, near the open-circuit voltage, the IV curve is strongly affected by the series resistance. A straight-forward method of estimating the series resistance from a solar cell is to find the slope of the IV curve at the open-circuit voltage point.
