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