摘要:
有机太阳电池(OPVs)和有机发光二极管(OLEDs)的阴极界面通常由有机小分子、聚电解质以及低温溶胶凝胶法加工的金属氧化物(最常见的为ZnO)制备而成,由于这些材料导电性不佳使光电器件中阴极界面薄膜厚度限制在30 nm以下,给大面积生产提出了苛刻要求。有机无机杂化的光电导材料是近来提出的有效提高阴极界面材料电导率的新策略。有机分子具有较高的消光系数,能够在低掺杂浓度下高效吸收可见光,而金属氧化物具有较高的电子迁移率,从有机分子到金属氧化物的光致电子转移能够有效填充金属氧化物中的电子陷阱(缺陷),同时大幅度增加金属氧化物中的载流子密度,因而,这种有机无机杂化的电极修饰材料具有优异的光电导性能。最近,报道通过掺杂一类苝酰亚胺光敏剂到无定形ZnO薄膜中,显著提高ZnO薄膜在光照下的电导率,解决了ZnO薄膜电导率低的科学问题。将这种杂化的光电导材料用于OPVs与OLEDs器件中,显著提高了器件性能,同时大幅度降低了电极修饰薄膜厚度对器件性能的影响,为大面积器件的快速制备提供了有利条件。
Abstract:
The cathode interlayers of organic photovoltaic cells (OPVs) and organic lightemitting diodes (OLEDs) are usually made from organic small molecules, polyelectrolytes and solgel processed metal oxides. The film thickness is usually limited under 30 nm due to the poor conductivity of these materials, which causes troubles for largescale production in future. Recently, the novel strategy of organicinorganic hybrid photoconductive interlayer materials by photodoped method was proposed to solve the low conductivity problem of cathode interlayer materials. Conjugated molecules possess high extinction coefficient while inorganic metal oxides typically show high electron mobility, thus, photoinduced electron transfer from organic molecules to metal oxides fulfills the electron traps in metal oxides and greatly enhances the charge carrier (electron) density at the same time, which result in very high photoconductivity. It has been reported that by doping a class of perylene imide photosensitizers into the amorphous zinc oxide film, the electrical conductivity under light irradiation is improved dramatically. Such photoconductive materials were used as cathode interlayers in OPVs and OLEDs, and greatly enhanced device performance was achieved even the film thickness was changed in very large range, which facilitates the large volume production in future.
