When a load is connected and the circuit is closed, the source voltage is divided across the load. But when the full-load of the device or circuit is disconnected and the circuit is opened, the open-circuit voltage is equal to the source voltage (assume ideal source).. The open-circuit voltage is used to mention a potential difference in solar cells and batteries.
The above equation shows that V oc depends on the saturation current of the solar cell and the light-generated current.
