采用混合溶剂制备了四苯基卟啉(TPP)及其铜配合物(TPPCu)和氯化对甲氧基四苯基铁卟啉(TMPPFeCl), 将三种卟啉化合物和富勒烯的衍生物(PCBM) 分别共混, 制备异质结太阳能电池。 器件结构是ITO/porphyrin∶PCBM/Al, 研究此类电池的性能。 结果显示基于TPP∶PCBM的器件性能最优, 其短路电流密度(JSC)是0.98 mA·cm-2, 开路电压(VOC)是0.52 V, 填充因子(FF)为30.1%。 TPP是三种卟啉化合物中最佳的给体材料。 进而考察了TPP∶PCBM的不同浓度配比对器件性能的影响。 TPP∶PCBM的最佳浓度配比为1∶1, 增加或减少TPP的量都会使器件的短路电流和开路电压降低, 对填充因子的影响不大。

Three kinds of porphyrins which can abbreviate as TPP, TPPCu and TMPPFeCl were synthesized by one-step method with mixed solvents. Then these porphyrin materials were used as donors to fabricate organic solar cells with PCBM as accepter by the solution processing of spin-coating method. The structure is ITO/porphyrin∶PCBM/Al. The photovoltaic characterizations of these devices were investigated. The device based on TPP∶PCBM shows the best performance with an open circuit voltage (VOC) of 0.52 V, a short circuit current (JSC) of 0.98 mA·cm-2, and fill factor (FF) of 30.1%. Then the influence of different weight ratio of TPP∶PCBM was researched. The best weight ratio of TPP∶PCBM is 1∶1. Increasing or decreasing the quatity of TPP would make JSC and VOC of the device deterioration and have little effect on the FF.
