“…[129][130][131][132] The percolated assembly of ultralong Ag NWs provides low sheet resistance (<10 Ω sq −1 ), 133,134 while maintaining high transparency owing to their highly porous structure. As Ag NWs are easily deposited on the target surface by spin casting or doctor blading, the Ag NW-based QLEDs can be cost-effective and highly flexible.…”

In the future electronics, all device components will be connected wirelessly to displays that serve as information input and/or output ports. There is a growing demand of flexible and wearable displays, therefore, for information input/output of the nextgeneration consumer electronics. Among many kinds of light-emitting devices for these next-generation displays, quantum dot light-emitting diodes (QLEDs) exhibit unique advantages, such as wide color gamut, high color purity, high brightness with low turn-on voltage, and ultrathin form factor. Here, we review the recent progress on flexible QLEDs for the next-generation displays. First, the recent technological advances in device structure engineering, quantum-dot synthesis, and high-resolution full-color patterning are summarized. Then, the various device applications based on cutting-edge quantum dot technologies are described, including flexible white QLEDs, wearable QLEDs, and flexible transparent QLEDs. Finally, we showcase the integration of flexible QLEDs with wearable sensors, micro-controllers, and wireless communication units for the next-generation wearable electronics.

“…29 Second, surface plasmon resonances and optical waveguide effects of the AgNWs enhance the light absorption by the organic layer. 30 By these two mechanisms, the incident light on the organic layer is folded into the layer and the scattered light is reabsorbed by the organic layer, leading to additional current generations. We thus conclude that the AgNW electrode has a confinement effect of incident light into an organic layer.…”

Solution-processable AgNW electrodes are prepared by our mechanical press process and applied for organic photovoltaic (OPV) cells. OPV cells using the AgNW electrodes exhibit good power conversion efficiencies of 3.05% even with that of ITO electrode (3.06%). Our mechanical press process enable to make OPV cell with standard device structure of Glass/AgNWs/PEDOT:PSS/Organic layer/Al. Conventional AgNW electrode fabrication methods were not able to apply the standard device structure because of their high roughness. Our methods open a new application route of AgNWs as the transparent electrodes for OPV cells. The OPV cell performances indicate their high potential the AgNWs for a photovoltaic electrode as an alternative material for the conventional ITO electrode. Furthermore, our AgNW fabrication process is suitable to make an electrode on organic-based substrate materials, especially for paper fabricated from natural cellulose. The results showed in this report will open the door of paper electronics.

“…Guo and co‐workers experimentally demonstrated the efficiency enhancement of OPVs using 1D Ag nanograting electrode (strip width ≈55 nm) due to the SPR and waveguide effects, and the optimized PCE was enhanced by about 35% compared to that of the ITO device under unpolarized light illumination 99. Further enhancement in light harvesting efficiency can be expected by tuning the period of the Ag nanogratings to match the SPR‐enhanced spectral range with the absorption peak of the photoactive layer.…”

Organic photovoltaics (OPVs) hold great promise for next‐generation photovoltaics in renewable energy because of the potential to realize low‐cost mass production via large‐area roll‐to‐roll printing technologies on flexible substrates. To achieve high‐efficiency OPVs, one key issue is to overcome the insufficient photon absorption in organic photoactive layers, since their low carrier mobility limits the film thickness for minimized charge recombination loss. To solve the inherent trade‐off between photon absorption and charge transport in OPVs, the optical manipulation of light with novel micro/nano‐structures has become an increasingly popular strategy to boost the light harvesting efficiency. In this Review, we make an attempt to capture the recent advances in this area. A survey of light trapping schemes implemented to various functional components and interfaces in OPVs is given and discussed from the viewpoint of plasmonic and photonic resonances, addressing the external antireflection coatings, substrate geometry‐induced trapping, the role of electrode design in optical enhancement, as well as optically modifying charge extraction and photoactive layers.
