The multi-layer electrode (ZnS/Ag/MoO3) was optimized by investigating the formation of a continuous Ag thin film according to the base layer. The aggregation of the Ag atom was strictly limited on the ZnS layer, which showed the best thermal stability for Ag. The thermally evaporated 7-nm-thick Ag film with surface coverage of 99.6% was achieved on the ZnS layer. We fabricated the ZnS (25 nm)/Ag (7 nm)/MoO3 (5 nm) (Z25A7M5) multi-layer electrode, optimized through the numerical calculation. The transmittance of 83% at λ = 550 nm and sheet resistance of 9.6 Ohm/sq were recorded from the Z25A7M5 electrode. These results were mainly attributed to the uniform film-like morphology of the Ag thin film. The flexible OLEDs, based on the Z25A7M5 anode also showed feasible I–V–L characteristics compared to those of ITO-based devices. 相似文献

A MoOx(top)/Au/MoOx(bottom) multilayer was systematically designed for transparent electrodes in green OLEDs in terms of optical transmission and series resistance of the device. The enhancement in optical transmission of MoOx/Au/MoOx (MAM) structures is a result of a series of events, including the optical interference within the multilayers and the interaction of light with surface plasmon polaritons in the metal layer. For the maximum transmission, the optical interference occurring within the multilayers was simulated using a transfer matrix model to determine the optimum thickness of MoOx layers, and then the thickness of the Au interlayer was experimentally optimized for extraordinary optical transmission. In addition, the series resistance added by the top MoOx was characterized to confirm its negligible impact on the performance of the device. The optimum MoOx (40 nm)/Au (10 nm)/MoOx (40 nm) structure showed much higher transmission in the green-red region and lower sheet resistance than indium tin oxide (ITO). We have fabricated MAM-based OLEDs the driving voltage of which was significantly reduced to ∼5.5 V at a current density of 20 mA/cm2, and the current efficiency (11.46 Cd/A) was higher than that (10.91 Cd/A) of ITO-based OLEDs, demonstrating that the MAM electrode is a potential replacement for ITO in optical devices. 相似文献

叠层片式电感器(MLCI)其引出结构在热应力冲击下,可能会形成开路,降低了MLCI的可靠性,进而影响到电子线路的整体功能。针对实际应用过程中一例叠层片式电感器(型号CH1608H22N)的失效,采用X射线检查、金相检查等分析方法对电感器的失效机理进行了分析。结果表明引出电极与内电极结合部位的热致失效导致了开路,进而研究了引出结构对MLCI可靠性的影响,设计出了一种新的圆弧型引出结构,通过实验验证该结构的耐流特性比直角型引出结构的提高了50%,产品可靠性得以改善。 相似文献

传统平面内扭转(In-Plane Switching,IPS)模式的聚合物稳定蓝相液晶显示器件由于死区(Dead Zone)的存在,导致了透光率较低的问题。通过引入浮置电极(Floating Electrodes),增强死区上方的横向电场强度,可以解决这一问题,提高蓝相液晶显示器件的总体透过率。引入浮置电极的蓝相液晶显示器件的电光特性由Techwiz3D程序仿真予以分析。我们定量计算了电极尺寸、工作波长和电极错位对电光特性的影响。仿真结果表明,引入浮置电极的IPS模式蓝相液晶显示器件的透过率提高了约15%,对显示应用中常见的3种可见光波长(450nm,550nm,650nm)的总体透过率都达到了约90%。该新型器件结构能够显著提升蓝相液晶显示器件的透过率,使之在新一代显示技术发展和竞争过程中获得更大的优势地位。 相似文献

Flexible organic photovoltaic devices may soon find applications in various fields, such as portable electronics or building‐integrated photovoltaics, occupying market niches that are currently not covered by the prevailing photovoltaic technology based on silicon and other inorganic materials. For these applications, there is an urgent need to replace the commonly used indium tin oxide by transparent and electrically conductive materials that can be processed cost‐effectively by large‐area compatible printing and coating processes. Here, we fabricated P3HT/PCBM organic solar cells with a power conversion efficiency of 3.1% on a flexible, transparent and conductive woven fabric electrode. The electrode is produced by a roll‐to‐roll process and consists of a polymer‐embedded fibre/metal wire grid. Metal wires protrude as little as 5 µm from the electrode plane, providing electrical contact points on a smooth surface suitable for thin film deposition. The use of spatially resolved photocurrent mapping experiments showed a high level of detailed information, with the unexpected indication that there probably exists a maximum in the cell performance versus mesh size opening and that woven fabric electrodes with largest geometrical open area do not necessarily perform better.
