Obtention of solar cell parameters, through convergence of iterative cycles. Part 2: Application to experimental current-voltage measurements

In this Part 2 of this series of articles, the application of the iterative cycles CycleA and CycleB proposed in Part 1, to determine the solar cell parameters (the shunt resistance ([Formula: see text]), the series resistance ([Formula: see text]), the ideality factor (n), the light current ([Formula: see text]), and the saturation current ([Formula: see text])) on experimental current voltage (IV) and current density (JV) curves, is given. Several number of measured points per voltage ([Formula: see text]) are attempted, from approximately [Formula: see text] to [Formula: see text]. In one case, the application of the iterative cycles to IV curves showing the roll-over effect is discussed, while in another case, their application to solar panels is analysed, revealing that the iterative cycles can also be used in the case of solar panels, and not only for laboratory-made solar cells, in voltage ranges larger than [0 V,1 V]. Also, cases in darkness and under illumination are evaluated. In most cases, reasonable values are obtained for [Formula: see text] , [Formula: see text] , [Formula: see text] and [Formula: see text] , which simulated properly the IV or JV curves.
