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.
Fill factor FF usually takes values in the range 0.6 ÷ 0.9 [27, 28]. The efficiency of a photovoltaic cell determines how much solar energy is converted into useful (electrical) energy and is determined by the maximum power Pm [27, 28] S.

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.
For the measurement of module parameters like VOC, ISC, VM, and IM we need voltmeter and ammeter or multimeter, rheostat, and connecting wires. While measuring the VOC, no-load should be connected across the two terminals of the module. To find the open circuit voltage of a photovoltaic module via multimer, follow the simple following steps.
The photovoltaic effect is based on the creation of an electric current in a material, usually a semiconductor, upon light irradiation. When sunlight irradiates the solar cell, some photons are absorbed and excite the electrons, or other charge carriers, in the solar cell.
When we connect N-number of solar cells in series then we get two terminals and the voltage across these two terminals is the sum of the voltages of the cells connected in series. For example, if the of a single cell is 0.3 V and 10 such cells are connected in series than the total voltage across the string will be 0.3 V × 10 = 3 Volts.

The current from the solar cell is the difference between I L and the forward bias current. Under open circuit conditions, the forward bias of the junction increases to a point where the light-generated current is exactly balanced by the forward bias diffusion current, and the net current is zero. The voltage required to cause these two currents to balance is called the "open-circuit …

If you know the number of PV cells in a solar panel, you can, by using 0.58V per PV cell voltage, calculate the total solar panel output voltage for a 36-cell panel, for example. You only need to sum up all the voltages of the individual photovoltaic cells (since they are wired in series, instead of wires in parallel). Here is this calculation:
