6 FAQs about [Solar cells have high parallel resistance]

What are series and shunt resistances in solar cells?

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.

What are parasitic resistances in solar cells?

The most common parasitic resistances are series resistance and shunt resistance. The inclusion of the series and shunt resistance on the solar cell model is shown in the figure below. Parasitic series and shunt resistances in a solar cell circuit.

How does a shunt resistance affect a solar cell?

The effect of a shunt resistance is particularly severe at low light levels, since there will be less light-generated current. The loss of this current to the shunt therefore has a larger impact. In addition, at lower voltages where the effective resistance of the solar cell is high, the impact of a resistance in parallel is large.

What is parasitic series and shunt resistance in a solar cell?

Parasitic series and shunt resistances in a solar cell circuit. In most cases and for typical values of shunt and series resistance, the key impact of parasitic resistance is to reduce the fill factor. Both the magnitude and impact of series and shunt resistance depend on the geometry of the solar cell, at the operating point of the solar cell.

How do you calculate the shunt resistance of a solar cell?

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. The impact of the shunt resistance on the fill factor can be calculated in a manner similar to that used to find the impact of series resistance on fill factor.
