Solar cell load calculation method
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).

Open-Circuit Voltage
The above equation shows that V oc depends on the saturation current of the solar cell and the light-generated current. While I sc typically has a small variation, the key effect is the saturation current, since this may vary by orders of magnitude. The saturation current, I 0 depends on recombination in the solar cell. Open-circuit voltage is then a measure of …
IV Curve
The IV curve of a solar cell is the superposition of the IV curve of the solar cell diode in the dark with the light-generated current.1 The light has the effect of shifting the IV curve down into the fourth quadrant where power can be extracted from the diode. Illuminating a cell adds to the normal "dark" currents in the diode so that the diode law becomes:
