FUNDAMENTAL PROPERTIES OF SOLAR CELLS
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; the number of photons (i.e., the power of the incident light …
