    Abstract: A light emitting device includes an organic light emitting element arranged above a substrate and including an anode, an organic functional layer including an organic light emitting layer, and a cathode, a capacitive element including an upper electrode arranged between the substrate and the organic light emitting element so as to reflect light entering from the organic functional layer via the anode, a dielectric layer arranged between the substrate and the upper electrode, and a lower electrode arranged between the substrate and the dielectric layer, and an insulating layer arranged between the capacitive element and the organic light emitting element. The upper electrode is electrically insulated from the anode. A distance between the upper electrode and the organic light emitting layer is adjusted so as to improve efficiency of light extraction from the organic light emitting layer.

    Abstract: Organic polymer semiconductor-based polymer solar cells (PSCs) have attracted considerable research interest due to having excellent electrical, structural, optical, mechanical, and chemical properties. In the past 20 years, considerable efforts have been made to develop PSCs. Generally, poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) is used as a hole transport layer (HTL) of the PSC to enhance hole extraction efficiency, but highly acidic PEDOT:PSS destroys an indium tin oxide (ITO) electrode and an active layer and thus reduces the lifetime of the device. To avoid this problem, some attempts have been made to develop inverted PSCs having different electron transport layers (ETLs). However, such a device has limited power conversion efficiency (PCE) due to low electron mobility of the ETL. Therefore, attempts have been made to enhance the PCE of inverted PSCs using indium gallium zinc oxide (IGZO) having optimized indium (In), gallium (Ga), and zinc (Zn) contents. Accordingly, inverted PSCs that have ZnO or IGZO (having varying In:Ga:Zn molar ratios) as an ETL and have an ITO/ETL/PTB7:PC71BM/MoO3/Al structure have been constructed. The PCE of the inverted PSC can be increased from 6.22% to 8.72% using IGZO having an optimized weight ratio of In, Ga, and Zn.

    Abstract: A light-emitting display device is provided. In the light-emitting display device, an insulation stack is patterned to form an opening area in the insulation stack, and an overhang structure in the opening area. An auxiliary electrode is connected to a common electrode around the overhang structure, such that a voltage of the common electrode may be uniformed for each region, and a voltage drop may be prevented. And, an exposed sidewall of the insulation stack surrounding the opening area is covered with the protective electrode, such that exposure of the insulation stack may be prevented at the inside and the sidewall of the opening area and residue of the pixel electrode material may be prevented. In addition, an exposure of a non-uniform interface of the insulating stack is prevented during a process of forming the organic functional layer and the common electrode, so that the organic functional layer and the common electrode may be stably deposited and the coverage characteristics of the encapsulation layer after forming the light-emitting device may be improved.
