Summary: Transparent electrodes are crucial components in optoelectronic device manufacturing. Indium tin oxide (ITO) is commonly used but it contains expensive and depleting indium. Silver nanowire (AgNW) electrodes offer an excellent alternative with their superior properties. By embedding AgNWs between two layers of ZnO nanoparticles (ZnONPs), the optical and electrical performance can be greatly improved. In solar cell architectures, the validation of the ZnONPs/AgNWs/ZnONPs electrode shows increased absorption, shorter exciton lifetime, and improved photovoltaic performance compared to ITO-based reference.

Summary: This study presents a fabrication process for high-performance and simple transparent conducting electrodes (TCEs) using metal nanowires. By combining direct metallization and plating processes on electrospun nanowires, the researchers successfully produced Ag-Cu core-shell nanowires and eliminated nanowire junction resistances. The process allows for adjustable transmission and sheet resistance properties. The resulting TCEs have low haze, high visible light transmittance, and excellent chemical and bending durability.

Summary: This study explored the use of silicon nanowires (SiNWs) combined with gold nanoparticles (Au NPs) for surface-enhanced Raman scattering (SERS) of probe molecules. The research found that the filling factor of SiNW arrays controlled the SERS efficiency, with the highest enhancement observed for samples with a porosity of 55%. The results demonstrate the electromagnetic enhancement of SERS through localized surface plasmon resonances in Au-NPs on SiNW surfaces, accompanied by light scattering in the SiNW arrays.

Summary: This study reports a method for developing high-performance flexible polymer solar cells using a high-throughput gravure printing process. By adjusting the blend ratio of the mixture solvent and the concentration of silver nanowire inks, the properties of the ink can be tuned to achieve uniformly printed films that meet the requirements of the printing process. The resulting flexible transparent electrodes exhibit high conductivity and transparency, comparable to traditional indium tin oxide electrodes.

Summary: This study demonstrated the design steps and optimization processes towards fully printed organic photovoltaic (OPV) modules with scalable processes for the first time, successfully fabricating devices with over 3.5 cm(2) active area and 5% efficiency. By addressing issues related to upscaling with printed electrodes through a rational design process, it also showed process compatibility of fully printed device structures with non-fullerene acceptor systems, enabling more opportunities for the design of high-performance OPV materials.

Summary: Graphene nanoribbons (GNRs) have attracted tremendous attention for their potential in next-generation nanoelectronic devices. The authors recently discovered that unzipping from double-walled carbon nanotubes (DWNTs) can produce crystalline single-layered GNRs (sGNRs) with high yield. By using silver nanowire-based tip-enhanced Raman spectroscopy (TERS), the authors analyzed the single GNRs and found heterogeneity in defect density and edge structure, which provides deeper insights into the structure and reaction mechanism of unzipped GNRs.
