For I SC matched cells it therefore remains to
consider voltage ranges where the exponential of some cells and the
linear shunt term of other cells of equation 1 are relevant for the
module current. To verify whether such combination can lead toI -V curve shapes that could be interpreted as intensity
dependent shunts, we plot in Fig. 7 the I -V curves of
modules with different shunt value distributions across the cells in the
module. The colored curves in Fig. 7 represent module circuits where
different amounts of the cells in the module have a notably lower shunt
resistance of 120 Ωcm² than the rest of the cells with a 10 kΩcm² shunt
of the standard set of 1-Diode cell model parameters in Table I. The
dashed lines represent modules with identical cells, each of them
described by the parameter set of Table I. The solid black lines
represent a linear variation of the of shunt conductance
1/RSh across the individual cells in the circuit.
