已知由传统的单二极管光电池模型和具有并联电阻的寄生二极管组成的相对的双二极管等效电路模型以某种方式再现了差的有机光电池的S形电流-电压曲线。在这里，在模型中的参数的光强依赖性进行了实验研究。在假设寄生部分对光不敏感的情况下，利用该模型拟合不同光照强度下的电流-电压曲线，得到寄生部分的参数，发现寄生部分的参数与健康光电池的参数一样发生变化。光敏主器件和光敏寄生器件的合理分离验证了模型的正确性。
The opposed two-diode equivalent-circuit model consisting of a traditional one-diode photocell model and a parasitic diode with a parallel resistance is known to somehow reproduce the S-shaped current-voltage curve of poor organic photocells. Here, the light-intensity dependencies of the parameters in the model are experimentally studied. On the assumption that the parasitic part is light-insensitive, the parameters of the main part, which are extracted by fitting the current-voltage curves under various illumination intensities with the model, are found to change as those of healthy photocells do. The reasonable separation of light-sensitive main and light-insensitive parasitic parts validates the model.
