If your global solar cell was not very uniform (rather likely for many solar cell types), your local solar cells may show wildly different behaviour. The IV characteristics of the, let''s say, 8 local cells that contain serious shunts (=short circuits) will be far more affected by this than your global cell (where you have another 9 992 shunt-free cells switched in parallel).
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.
