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
One of the biggest problems is that the cell series resistance is a lumped parameter composed of many resistances within the device. A solar cell is a three dimensional device and can be thought of as a network of resistors and diodes. As the level of current changes so does the apparent series resistance.
The area of the solar cell is 1 cm 2, the cell series resistance is zero, temperature is 300 K, and I 0 is 1 x 10 -12 A/cm 2. Click on the graph for numerical data. An estimate for the value of the shunt resistance of a solar cell can be determined from the slope of the IV curve near the short-circuit current point.
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.
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.
