Impact of Both Series and Shunt Resistance

In the presence of both series and shunt resistances, the IV curve of the solar cell is given by;

and the circuit diagram of the solar cell is given as;

恒大彩票网址是多少Parasitic series and shunt resistances in a solar cell circuit.

To combine the effect of both series and shunt resistances, the expression for FFsh, derived above, can be used, with FF0 replaced by FFs 1. The overall equation then becomes;

where FFs恒大彩票网址是多少 is given by;

恒大彩票网址是多少and by combining the above equations, the net equation for FF becomes;

Rs =

0.13

Rshunt =

101e5

The following calculator determines the effect of Rs and Rsh on the cell fill factor using the same variable definitions as above.
