The most commonly used equivalent circuit in PV is the one diode model. An ideal solar cell may be modelled by a current source in parallel with a diode; in practice no solar cell is ideal, so a shunt resistance and a series resistance component are added to the model. These two elements correspond to generation and loss of photocurrent in the device. Short circuit current - the current which would flow if the PV sell output was shorted 4. From the equivalent circuit it is evident that the current produced by the solar cell is equal to that produced by the current source, minus that which flows through the diode, minus that which flows through the shunt resistor: I = IL − ID − ISH.
