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 the amount of
