摘要
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0.98mA.cm-2,开路电压(VOC)是0.52V,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 s ynthesized by one-step method with mixed solvents.Then these porphyrin materia ls were used as donors to fabricate organic solar cells with PCBM as accepter by t he 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 vo ltage(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 differ ent weight ratio of TPP∶PCBM was researched.The best weight ratio of TPP∶PCB M 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.
