在实验工作的基础上，提出了双层ｐ－ｎ异质结有机太阳能电池中激子和载流子输运的理论模型，假设只有扩散到结区的激子和该区产生的激子，才对形成光电流有贡献。这些激子被有机／有机界面的内建场离解成自由载流子。而后，电子在红（ｎ型有机半导体）层传导，空穴在酞菁（ｐ型有机半导体）层传导。据此，讨论了在红／酞菁异质结电池中，红（Ｍｅ－ＰＴＣ）层和铝氯酞菁（ＣｌＡｌＰｃ）层之间的Ｆｏｒｓｔｅｒ能量转移以及填充因子和光电转换效率均较单层肖特基型电池获得改善的机制。
Based on the experimental work, a theoretical model of exciton and carrier transport in a two-layer p-n heterojunction organic solar cell is proposed. Supposing that there are only excitons and excitons generated in the junction region, Only on the formation of photocurrent contribution. These excitons are dissociated into free carriers by the built-in field of the organic / organic interface. Then, the electrons are conducted in the red (n-type organic semiconductor) layer, and the holes are conducted in the phthalocyanine (p-type organic semiconductor) layer. Accordingly, the Forster energy transfer and the fill factor and the photoelectric conversion efficiency between the Me-PTC layer and the aluminum chlorophthalocyanine (ClAlPc) layer in the red / phthalocyanine heterojunction cell are discussed. Layer Schottky cells get an improved mechanism.
