Solar Cell Voltage-Current Characterization
Short circuit current, Isc, flows with zero external resistance (V= 0) and is the maximum current delivered by the solar cell at any illumination level. Similarly, the open circuit voltage, Voc, is the potential that develops across the terminals of the solar cell when the external load resistance is very large (Figure 3).
IV Curve
Several important parameters which are used to characterize solar cells are discussed in the following pages. The short-circuit current (I SC), the open-circuit voltage (V OC), the fill factor (FF) and the efficiency are all parameters determined from the IV curve.
