摘要
在有机电致发光器件(OLEDs)中,由于存在多种光子束缚模式,其光提取效率很低。在有机太阳能电池(OPVs)中,有机材料的载流子迁移率较低,需要控制有源层厚度,导致光吸收不足,降低光电转换效率。利用金属等离子体微纳结构调控有机光电器件中的光场分布,是提高器件效率的有效方法之一。对基于金属等离子体微纳结构调控有机光电器件光场分布的最新研究进展进行总结,并详细讨论利用等离子体金属结构提高OLEDs的光提取效率和OPVs的光吸收效率的机理和方法。
Abstract
The photon extraction efficiency of the organic light-emitting devices (OLEDs) is considerably low because of the presence of various light-trapping modes. The power conversion efficiency of organic photovoltaics (OPVs) is also unsatisfactory because of the incomplete light absorption induced by the low diffusion length of the organic active materials which limit the thickness of active layer. An effective method to improve the efficiency of the organic optoelectronic devices is to use the metal plasmonic micro/nano-structures for regulating the light-field distribution. This review article summarizes the recent advances in light-field manipulation induced by the metallic subwavelength structures in organic optoelectronic devices. Furthermore, the principles and strategies for enhancing the light extraction in OLEDs and light harvesting in OPVs, are discussed in this study.
