在本系列文章的第2部分中，讨论了文献报道的通过使用Co含量函数CCV，I= Isc0VI −IscdV（其中Isc=I（V=0））获得太阳能电池参数（分流电阻（R sh）、串联电阻（R s）、理想因子（n）、光电流（I lig）和饱和电流（I sat））的方法。在第1部分中报告的结果，即，作为每电压（PV）和噪声百分比（pn）的测量点的数量的函数的R sh、Rs、n、I lig和I sat的测定的准确度依赖性，用于分析报告的太阳能电池参数。在一种情况下，讨论了CCV，I在太阳能电池板上的应用，揭示了它也可以用于太阳能电池板的情况，而不仅仅是用于实验室制造的太阳能电池，电压范围大于[0 V，1 V]。在另一种情况下，讨论了CCV，I到IV曲线显示翻转效应的应用。研究发现，在太阳参数提取中，滚转效应是一个非常有害的因素，因此，在滚转效应发生之前，必须计算CCV，I。在第三种情况下，正确确定的重要性Isc的正确计算CCV，我进行了讨论。
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.
