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. IV curve of a solar cell showing the short-circuit current.
While measuring the ISC, no-load should be connected across the two terminals of the module. To find the short circuit current of a photovoltaic module via multimer, follow the simple following steps. Make sure that one probe is connected to the COM port of multimeter and another to the current measuring port.
It is the current the solar panel produces when no load is connected to it. Short-circuit current (Isc) can be measured by connecting the positive and negative terminals of the panel to each other through an ammeter in series. While measuring Isc on your own is usually safe and does not harm the panel, care must be taken to avoid arcing.
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.
Short Circuit Current (Isc) Short Circuit Current is how many amps (i.e. current) the solar panels produce when they are not connected to a load but when the panel wires ‘ positive and negative terminals are connected directly to each other. If you only measure the positive and negative terminals with an ammeter, you’ll read Isc.
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.

We also know that multiple pv panels can be connected together to form a pv array which can produce more solar output power than just one single solar panel. A photovoltaic solar cell produces current over a range of voltages from 0V (short-circuit) to its maximum open-circuit voltage at V OC.
By optimizing the short-circuit current of the solar panels, system designers can ensure that the system operates at its maximum power output, resulting in higher energy generation and increased efficiency. Additionally, Isc is used to determine the overall efficiency of a solar energy system. By comparing the actual current output of the system with the short …
