Solar cell resistance is high

THE BEHAVIOUR OF SOLAR CELLS

Solar cells generally have a parasitic series and shunt resistance associated with them, as shown in Fig. 3.10. Both types of parasitic resistance act to reduce the fill-factor.

Shunt Resistance

Low shunt resistance causes power losses in solar cells by providing an alternate current path for the light-generated current. Such a diversion reduces the amount of current flowing through the solar cell junction and reduces the voltage from the solar cell. The effect of a shunt resistance is particularly severe at low light levels, since

Influence of injection level and wafer resistivity on series resistance

6 FAQs about [Solar cell resistance is high]

What is the characteristic resistance of a solar cell?

The characteristic resistance of a solar cell is the cell's output resistance at its maximum power point. If the resistance of the load is equal to the characteristic resistance of the solar cell, then the maximum power is transferred to the load, and the solar cell operates at its maximum power point.

What causes series resistance in a solar cell?

What causes shunt resistance in a solar cell?

Shunt resistance (R s h) is created due to leakage currents produced at the edge of the f-PSCs and the imperfection of the cell structure . This affects the parallel conductivity of a solar cell depending on the cell junction [, , , ]. As leakage currents increase, the efficiency of any solar cell decreases.

How does series resistance affect the IV curve of a solar cell?

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.

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.

Does series resistance affect a solar cell at open-circuit voltage?

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.
