Fundamental aspects concerning the validity of the standard equivalent circuit for large-area silicon solar cells

In this work it is shown why the equivalent circuit model holds for large-area silicon solar cells (i.e., why it is permitted to decouple series resistance and diode effects), and that for the equivalent circuit model to hold, it has to account for the decrease of the lumped series resistance in dependence on the dark current. This is expressed by the effective diode resistance RD in the modified equivalent circuit shown above.
