介绍并讨论了一种描述不同偏光水平下体异质结聚合物太阳电池的电流-电压特性的扩展替换电路。用光生载流子的提取模型对单二极管模型进行了扩展，该模型考虑了当扫描偏压穿过太阳能电池的第四象限时电荷载流子覆盖的平均距离的有效减少。该模型用一组参数很好地描述了光强超过三个数量级的体相异质结太阳电池的电流-电压行为。(C)2004年美国物理研究所。
An extended replacement circuit describing the current-voltage characteristics of bulk heterojunction polymer solar cells at different light bias levels is introduced and discussed. A one diode-model is expanded by an extraction model for photogenerated carriers taking into account the effective reduction of the mean distance which the charge carriers cover when sweeping the electrical bias through the fourth quadrant of the solar cell. The model properly describes the current-voltage behavior of bulk heterojunction solar cells over more than three orders in light intensity with one set of parameters.
