“…Finally, in terms of device stability, OLEDs composed of organic materials which can be easily oxidized are vulnerable to oxygen and moisture so a glass lid is usually used to protect OLEDs on glass substrates. However, the glass lid encapsulation technique is not suitable for flexible OLEDs, so thin‐film encapsulation (TFE) has been suggested as a promising candidate, and various techniques such as Barix encapsulation, multibarrier comprising inorganic/organic layers, and, nanolaminates, have been exploited to accomplish the successful commercialization of flexible OLEDs.…”

Advances in material science and nanotechnology have fostered the miniaturization of devices. Over the past two decades, the form‐factor of these devices has evolved from 3D rigid, volumetric devices through 2D film‐based flexible electronics, finally to 1D fiber electronics (fibertronics). In this regard, fibertronic strategies toward wearable applications (e.g., electronic textiles (e‐textiles)) have attracted considerable attention thanks to their capability to impart various functions into textiles with retaining textiles' intrinsic properties as well as imperceptible irritation by foreign matters. In recent years, extensive research has been carried out to develop various functional devices in the fiber form. Among various features, lighting and display features are the highly desirable functions in wearable electronics. This article discusses the recent progress of materials, architectural designs, and new fabrication technologies of fiber‐shaped lighting devices and the current challenges corresponding to each device's operating mechanism. Moreover, opportunities and applications that the revolutionary convergence between the state‐of‐the‐art fibertronic technology and age‐long textile industry will bring in the future are also discussed.

“…Bulk heterojunction (BHJ) organic solar cells (OSCs) consisting of electron donor and electron acceptor as light absorbers have attracted broad attention due to their advantages of flexibility, light weight and low cost . Over the last thirty years, great efforts have been made to promote the rapid progress of OSCs, leading to over 17% power conversion efficiencies (PCEs) .…”

Efficient Organic Solar Cells with a High Open‐Circuit Voltage of 1.34 V

Summary of main observation and conclusion One of the most important challenges that hinders the power conversion efficiencies (PCEs) of organic solar cells (OSCs) is the modest open‐circuit voltages (VOC) due to large energy losses. The large driving force during for charge generation and the non‐radiative recombination are the main causes of energy losses. To maximize the VOC of OSCs, herein, we modulate the end‐groups and design a non‐fullerene acceptor ITCCM‐O, which shows a bandgap of 2.0 eV. By blending a polymer donor named J52, the device demonstrates a PCE of 5.5% with an outstanding VOC of 1.34 V, which is the highest value for single‐junction OSCs over 5% PCEs. The high VOC is benefited from 1) the negligible driving force for charge transfer, and 2) the suppressed non‐radiative recombination loss, as low as 0.22 V.

Phototherapeutics is both safely noninvasive and can be employed to treat a variety of sites and diseases. Current rigid and bulky conventional light sources, such as LED or laser-based phototherapy devices, are difficult to transport and use for regular irradiation treatments. To solve this problem, flexible organic light-emitting diode (OLED) light sources are the best candidates, and if applied very thinly as a skin-like platform, the ultimate attachable phototherapeutics can be realized. We demonstrated a very thin flexible OLEDbased photonic skin with a total thickness of 6 μm for application in attachable phototherapeutics. It was optimized by controlling the peak wavelengths (600-700 nm) and irradiation interval of the flexible OLED thus improving the regeneration effect of the artificial skin by up to 70%. In addition, when the flexible OLED-based photonic skin was attached to a dressing film before being applied to the skin, it delivered the same electro-optical properties, while protecting against external contamination. The OLED skin on the dressing film had an operating lifetime of more than 100 h. These results confirmed the applicability of flexible OLED-based photonic skin to various light treatment areas, such as surgical wounds that require periodic irradiation.
