| 제목 | Packaging strategies for high performance barrier layers for organic photovoltaic devices |
| 초록 | Over the past decade, rapid advances in organic semiconducting materials and their processing techniques have led to the development of organic light-emitting diodes (OLEDs), organic photovoltaics (OPVs), and organic thin-film transistors (OTFTs) with unprecedented performance. Interest in such organic electronic devices arises due to their wide range of tunable properties, multi-functional characteristics, and potential for use in flexible electronics as well as their amenability to wide-area manufacturing processes such as inkjet or gravure printing. While these devices have many advantages, it is well known that environmentally-induced degradation of the active materials and low work function electrodes remains a valid concern. In this work, we will present results on the development of our various thin-film encapsulation structures produced by different fabrication methods and suggest packaging strategies for longer lifetime of organic devices. Developed hybrid structure consisting of SiNx coated with a layer of Al2O3 (Patent published, US2010/0132762A1 and WO2010/065564A1) was characterized by using Ca corrosion test. The hybrid layer obtained a WVTR of 5 × 10-5 g/m2/day and the lifetime of encapsulated devices will be presented. |
