Photovoltaic (PV) Cell: Characteristics and Parameters
Above the short-circuit point, the PV cell operates with a resistive load. Between the short-circuit point and the knee of the curve, the output power depends on the voltage because the current is essentially constant. The maximum output power occurs in the knee at the point, called the maximum power point (MPP), where the voltage is ...

Power delivered by the PV cell is the product of voltage (V) and current (I). At both open and closed circuit conditions the power delivered is zero. At some point in between (around the knee point) the delivered power is a maximum. Note: the maximum amount of current that a PV cell can deliver is the short circuit current. Given the …

An equivalent circuit model of an ideal solar cell''s p–n junction uses an ideal current source (whose photogenerated current increases with light intensity) in parallel with a diode (whose current represents recombination losses). To account for resistive losses, a shunt resistance and a series resistance are added as lumped elements. The resulting output current equals the photogenerated curr…
