Here, considering this conceptual earth surface, the I–V relationship with the
exception of I–V curve, a calculative result of linked I–V curves among all of the
conceptual solar cells has been determined [49, 51]. Thus, the equation is being
rewritten as follows in order to determine the V–R relationship much more
accurately:

where I Lmo denotes the photon-induced current, I omo denotes the dynamic current
into the diode, R smo denotes the resistance in series, and K mo denotes the factorial
constant.
Once all non-series (Ns) cells are being interlinked in the series, then the series
resistance is calculated as the sum of each solar cell series resistance R smo = N s × R s
current considering the functional coefficient of the constant factor K mo = N s × K. Since
the flow of current dynamics into the circuit is lined to the cells in a series connection, the current dynamics in Eq. (2.40) remains the same in each part of I omo = I o and
I Lmo = I L . Thus, the mode of I mo –V mo relationship for the N s series of connected cells
can be expressed by
