![]() For most solar cell measurement, the spectrum is standardised to the AM1.5 spectrum Isc from a solar cell is directly dependant on the light intensity as discussed in Effect of Light Intensity the number of photons (i.e., the power of the incident light source).To remove the dependence of the solar cell area, it is more common to list the short-circuit current density (J sc in mA/cm 2) rather than the short-circuit current The short-circuit current depends on a number of factors which are described below: Therefore, the short-circuit current is the largest current which may be drawn from the solar cell. For an ideal solar cell at most moderate resistive loss mechanisms, the short-circuit current and the light-generated current are identical. The short-circuit current is due to the generation and collection of light-generated carriers. IV curve of a solar cell showing the short-circuit current. ![]() Usually written as I SC, the short-circuit current is shown on the IV curve below. 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). ![]()
