A graphical presentation of the currentSee electric current. versus the voltageThe amount of electromotive force, measured in volts, that exists... from a photovoltaic device as the loadThe demand on an energy producing system; the energy consumption... is increased from the short circuit (no loadThe demand on an energy producing system; the energy consumption...) condition to the open circuit (maximum voltageThe amount of electromotive force, measured in volts, that exists...) condition. The shape of the curve characterizes cell performance.
