See No Load Voltage.
The maximum possible voltage across a photovoltaic cell or module; the voltage across the cell in sunlight when no current is flowing.[to top
The no-load voltage of a cell or battery measured with a high-impedance voltmeter at a temperature of 20° C.
The voltage that a alternator or generator produces when it is NOT connected to a Load.
Abbreviated Voc, refers to a PV device's voltage potential when it is providing no current.
The voltage of a battery when there is no net current flowing.
oc): The voltage across a photovoltaic cell or module in sunlight when no current is flowing; the maximum possible voltage. Unit: V.
The measured voltage of the cell or battery without a load attached.
the voltage applied across the output terminals of a ballast when no load is connected. This is the voltage applied across a lamp circuit to start a lamp. After starting, the voltage rapidly decreases and stabilizes at the operating voltage.
(Voc)- The maximum possible voltage across a photovoltaic cell or module in sunlight when no current is flowing.
As the name implies, no current is flowing in the circuit because the circuit is open. The voltage is impressed upon the circuit, however, so that when the circuit is completed, the current will flow immediately. For example, a welding machine that is turned on but not being used for welding at the moment will have an open-circuit voltage applied to the cables attached to the output terminals of the welding machine.

A PV cell or module's voltage potential in sunlight when there is no current flowing.
The difference in potential between the terminals of a cell when the circuit is open (i.e., a no-load condition).
The voltage read at the output of a transformer or power supply without a load.
Open-circuit voltage or OCV is the difference of electrical potential between two terminals of a device when there is no external load connected, i.e. the circuit is broken or open. Under these conditions there is no external electric current flow between the terminals, although there may be current flow internally (e.g. self-discharge currents in batteries). It is sometimes given the symbol Voc.
