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.
Single crystal solar cells are often 15.6 × 15.6 cm 2, giving a total current of almost 9 – 10A from a module. The table below shows the output of typical modules at STC. I MP and I SC do not change that much but V MP and V OC scale with the number of cells in the module.
Short-circuit current: In the case of a short-circuit condition of a solar cell, current is drawn, i.e., the cell does not have voltage. This current is symbolized as I S C (from the current of the short-circuit configuration). I S C = − I L means that the magnitude of the short-circuit current is equal to the absolute light-current value.
Series and shunt resistances in solar cells are parasitic parameters, which affect the illuminated current–voltage (I–V) characteristics and effi ciency of cells. Very high values of series resistance (R s) and very low values of shunt resistance (R sh) reduce short-circuit current density (J sc) and open-circuit voltage (V oc), respectively.
The overall IV curve of a set of identical connected solar cells is shown below. The total current is simply the current of an individual cell multiplied by the number of cells in parallel. Such that: ISC total = ISC × M. The total voltage is the voltage of an individual cell multiplied but the number of cells in series.
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.
