报道了通过添加可溶酞菁衍生物1,4,8,11,15,18,22,25-辛己基酞菁（C6PcH2）提高聚（3-己基噻吩）（P3HT）有机薄膜太阳能电池长波灵敏度的研究进展。c6pch22具有近红外吸收特性，可与P3HT:1-（3-甲氧基-羰基）-丙基-1-1-苯基-(6,6)C61 （PCBM）本体异质结活性层混合。在P3HT:C6PcH2:PCBM=10:3:10的组成比下，C6PcH2的光敏性得到提高，能量转换效率达到3.0%。本文讨论了基于P3HT:C6PcH2:PCBM有源层的体异质结太阳能电池的光电转换原理，同时考虑了P3HT高度有序结构和C6PcH2的六方柱状结构，以及P3HT和C6PcH2在有源层中的微相分离。
The improvement of long-wavelength sensitivity in bulk heterojunction organic thin-film solar cells based on poly(3-hexylthiophene) (P3HT) by the addition of the soluble phthalocyanine derivative, 1,4,8,11,15,18,22,25-octahexylphthalocyanine (C6PcH2) is reported. C6PcH2possesses near-infrared absorption and can be mixed with a P3HT:1-(3-methoxy-carbonyl)-propyl-1-1-phenyl-(6,6)C61 (PCBM) bulk heterojunction active layer. By doping C6PcH2, the photosensitivity in the long-wavelength region was improved, and the energy conversion efficiency reached 3.0% at a composition ratio of P3HT:C6PcH2:PCBM=10:3:10. We discuss the principle of photoconversion in the bulk heterojunction solar cell based on the P3HT:C6PcH2:PCBM active layer by taking into consideration the existence of both highly ordered P3HT domains and hexagonal columnar structures of C6PcH2, and the microphase separation of P3HT and C6PcH2in the active layer.
