The short-circuit current is the current through the solar cell when the voltage across the solar cell is zero (i.e., when the solar cell is short circuited). Usually written as I SC, the short-circuit current is shown on the IV curve below. IV curve of a solar cell showing the short-circuit current.
The short- and open-circuit operation conditions of a solar cell are defined as a RL which is equal to zero or which is infinitely high, respectively. The values of the photocurrent and of the photovoltage at short- and open-circuit conditions are called short-circuit current (ISC) and open-circuit voltage (VOC), respectively.
solar cell has two basic functions: the generation of a photocurrent and the generation of a photovoltage for the production electric power. The maximum electric power of an illuminated solar cell is the product of the ISC, the VOC and the FF. Loads are used to extract the power from solar cells.
Under open circuit conditions, the light-generated carriers forward bias the junction, thus increasing the diffusion current. Since the drift and diffusion current are in opposite direction, there is no net current from the solar cell at open circuit.
Charge separation at a charge-selective contact inside the solar cell is the origin for an internal voltage source and leads to the generation of a photovoltage. The current or photocurrent is often normalized to the area of the solar cell under consideration.

Basic Characteristics and Characterization of Solar Cells
The basic characteristics of a solar cell are the short-circuit current (ISC), the open-circuit voltage (VOC),the fill factor (FF) and the solar energy conversion efficiency (η). The influence of both the diode saturation current density and of ISC on VOC, FF and is analyzed for ideal solar cells.

What is short circuit current in solar cell?
Short circuit current (Isc) in solar cells is a crucial parameter reflecting their electrical performance. Isc is typically thought to be limited by the lowest subcell photocurrent (Imin) in multijunction photovoltaic cells. However, research has shown that Isc can deviate from Imin in certain conditions, with factors like the number of ...

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…
