Shunt Resistance
The presence of a low shunt resistance provides an easier path for the light-generated current. This reduces the amount of current flowing through the solar cell and also reduces the voltage from the solar cell [70,98]. As the shunt resistance increases, the current moving in the load increases too as shown in Fig. 7 [99] [100], as governed by Eq.
