Shunt Resistance

The effect of shunt resistance on fill factor in a solar cell. 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.

Shunt Resistance Calculator

The shunt resistance always has a very low resistance value. Thus, the current seeks a path through the shunt resistance instead of the ammeter or the other measuring devices. When current goes through the circuit, the shunt resistor is where a portion of it appropriately flows, while the total of the rest sues the original path.
