Short circuit current is the current passing through a solar cell when voltage is zero across the solar cell, which happens when a solar cell is short circuited. Usually it is denoted Isc. The short circuit current results from collection and generation of light generated carriers.

When comparing solar cells of the same material type, the most critical material parameter is the diffusion length and surface passivation. In a cell with perfectly passivated surface and uniform generation, the equation for the short-circuit current can be approximated as: n p are the e-and h+diffusion lengths respectively.
For an ideal solar cell at most moderate resistive loss mechanisms, the short-circuit current and the light-generated current are identical. Therefore, the short-circuit current is the largest current which may be drawn from the solar cell. The short-circuit current depends on a number of factors which are described below:
In the case of very high series resistance (> 10 Ωcm 2) I sc is less than I L and writing the solar cell equation with I sc is incorrect. Another assumption is that the illumination current I L is solely dependent on the incoming light and is independent of voltage across the cell.
