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;
To combine the effect of both series and shunt resistances, the expression for FFsh, derived above, can be used, with FF0 replaced by FFs 12元微信红包小扫雷群. The overall equation then becomes;
where FFs is given by;
2元微信红包小扫雷群and by combining the above equations, the net equation for ff becomes;
The following calculator determines the effect of Rs and Rsh on the cell fill factor using the same variable definitions as above.
