Open-circuit voltage - Wikipedia
Open-circuit voltage (abbreviated as OCV or V OC) is the difference of electrical potential between two terminals of a device when disconnected from any circuit. There is no external load connected. No external electric current flows between the terminals. Alternatively, the open-circuit voltage may be thought of as the voltage that must be applied to a solar cell or a …
