Why does solar cell performance use short-circuit current per unit …
$begingroup$ Got to be a bit careful with terminology because they don''t store energy, it''s being converted from sunlight and flowing out as current in a finite amount of time. It''s a stretch to call that storing energy. But I get what you mean. A larger cell has more photo generated electrons but the same number of photo generated electrons per …

1. Introduction. The most important parameters characterizing a solar cell are the open circuit voltage V oc, the short circuit current I sc and the fill factor FF.Since the cell efficiency is proportional to the product of these three numbers, optimization of a solar cell can be achieved by increasing any of these.

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…

Open Circuit Voltage
The short-circuit current density is the photocurrent generated by the solar cell, expressed in the form of the current density under zero external field (i.e., 0 V). The flow of the photogenerated carriers to the electrode primarily depends on the built-in field of the solar cell. The short-circuit current density can be estimated as [45]:
FUNDAMENTAL PROPERTIES OF SOLAR CELLS
Short circuit photocurrent (ISC) The short-circuit current depends on a number of factors which are described below: the area of the solar cell. To remove the dependence of the so lar cell area, it is more common to list the short-circuit current density (Jsc in mA/cm2) rather than the short-circuit current;
Short-Circuit Current Density
The ratio of short circuit or maximum current (I sc) to the active surface area of a solar PV cell (i.e., the area exposed to sunlight), A, is a significant parameter in the traditional PV solar energy harnessing because the output current produced by a PV cell is dependent on the surface area exposed to sunlight, where photocurrent is generated and across which …
