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:

Open circuit voltage (V OC) is the most widely used voltage for solar cells specifies the maximum solar cell output voltage in an open circuit; that means that there is no current (0 amps).We can calculate this voltage by using the open circuit voltage formula for solar cells.

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 …
