N2 - In this Part 2 of this series of articles, a discussion of the literature reported obtention of the solar cell parameters (the shunt resistance (R sh ), the series resistance (R s ), the ideality factor (n), the light current (I lig ), and the saturation current (I sat )), via the use of the Co-content function CCV,I= ∫0VI-IscdV (where Isc=I(V=0) ) is given. The results reported in Part 1, namely, the accuracy dependence of the determination of R sh , R s , n, I lig , and I sat , as a function of the number of measured points per voltage ( PV ) and percentage noise ( pn ) is used to analyse the reported solar cell parameters. In one case, the application of CCV,I to solar panels is discussed, revealing that it 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]. In another case, the application of CCV,I to IV curves showing the roll-over effect is discussed. It is found that the roll-over effect has a pernicious effect in the solar parameter extraction, and then the CCV,I should be calculated before the roll-over effect takes place. In a third case, the importance of the correct determination of Isc on the correct calculation of CCV,I is discussed.
