The use of Dark IV curves in solar cell analysis relies on the principle of superposition. That is, in the absence of resistive effects, that the light IV curve is the dark IV curve shifted by the light generated current. While this is true for most cells it is not always the case.
A nonlinear least squares approach to extract the cell parameters from the dark current-voltage (I-V) characteristics is described. The fit of the I-V curve and the extraction of diode parameters are carried out by considering the I-V characteristics of the cell in dark condition.

The current-voltage (I-V) curve for each component cell in the PV module is characterized by PV cell specific parameters' values.
Dark current-voltage (I-V) response determines electrical performance of the solar cell by providing reliable and accurate information regarding its series and shunt resistances, diode factor, and diode saturation currents; the diode parameters determine the quality of metallization and solar cell efficiency.
That is, in the absence of resistive effects, that the light IV curve is the dark IV curve shifted by the light generated current. While this is true for most cells it is not always the case. A second problem is that in dark IV measurements the current is flowing in the opposite direction and the current paths are different.
Deep analyses were carried out on dark- and illuminated I–V curves, and dark C–V curves. Results were compared with those of graded bandgap solar cells fabricated on inorganic n-type window layers.
