The short-circuit current (ISC) 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 ISC, the short-circuit current is shown on the IV curve below. ISC is due to the generation and collection of light-generated carriers.
s of the solar cell are short circuited. The short-circuit current of a solar cell de-pends on the photon flux incident on the solar cell, which is determin d by the spectrum of the incident light. For standard solar cell measurements, the spectr m is standardised to the AM1.5 spectrum. The I c depends on the a
Let’s take an example, a solar cell has a current density of 40 mA/cm2 at STC and an area of 200 cm2. Then the short circuit current can be determined as follows; ISC = Jsc × Area = 40 mA/cm2 × 200 cm2 = 8000 mA = 8 A Open circuit voltage is the maximum voltage that the cell can produce under open-circuit conditions.
As can be seen from table 1 and figure 2 that the open-circuit voltage is zero when the cell is producing maximum current (ISC = 0.65 A). The value of short circuit depends on cell area, solar radiation on falling on cell, cell technology, etc. Sometimes the manufacturers give the current density rather than the value of the current.

The resistance and the multimeter are connected in parallel with the illuminated solar cell (Figure 1.15(a)). The current is found by Ohm’s law from the values of the resistance and the measured voltage. The values of suitable RL can be estimated by the following procedure.
