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.
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.
Significant power losses caused by the presence of a shunt resistance, RSH, are typically due to manufacturing defects, rather than poor solar cell design. Low shunt resistance causes power losses in solar cells by providing an alternate current path for the light-generated current.
Moreover, the modelling can be used to define the solar cell string layout associated to different PV collector configurations in order to improve their performance accordingly with he defined requirements.
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 there will be less light-generated current. The loss of this current to the shunt therefore has a larger impact.
The article shows effect of series (R s) and shunt resistances (R s h) on solar cell parameters to enhance the photovoltaic performance of f-PSCs. Single diode model has been employed to analyzed the results. Better morphology has been achieved by using antisolvent.
