An equivalent circuit model of an ideal solar cell's p–n junction uses an ideal current source (whose photogenerated current increases with light intensity) in parallel with a diode (whose current represents recombination losses). To account for resistive losses, a shunt resistance and a series resistance are added as lumped elements.
For most crystalline silicon solar cells the change in VOC with temperature is about −0.50%/°C, though the rate for the highest-efficiency crystalline silicon cells is around −0.35%/°C. By way of comparison, the rate for amorphous silicon solar cells is −0.20 to −0.30%/°C, depending on how the cell is made.
It can be shown that for a high-quality solar cell (low RS and I0, and high RSH) the short-circuit current is: It is not possible to extract any power from the device when operating at either open circuit or short circuit conditions. The values of IL, I0, RS, and RSH are dependent upon the physical size of the solar cell.
