“…These results suggest that the optoelectrical performance degradation of metal oxide/metal NW TCEs can be minimized if the FoM difference between the metal oxide and the metal NW is small. Our c-ITO/metal NW-GFRHybrimer films exhibit an excellent optoelectrical performance compared with those of the state-of-the-art metal NW composite TCEs; 26,29,36 for example, values of R sh = 17.2 Ω sq − 1 at T tot = 92.3% for c-ITO/AgNW-GFRHybrimer and R sh = 19 Ω sq − 1 at T tot = 92.2% for c-ITO/CuNW-GFRHybrimer were achieved ( Table 1). The introduction of a metal oxide layer, by filling the voids between the metal NW networks, can help inducing additional charge for carrier collection/injection.…”

Here, we propose crystalline indium tin oxide/metal nanowire composite electrode (c-ITO/metal NW-GFRHybrimer) films as a robust platform for flexible optoelectronic devices. A very thin c-ITO overcoating layer was introduced to the surface-embedded metal nanowire (NW) network. The c-ITO/metal NW-GFRHybrimer films exhibited outstanding mechanical flexibility, excellent optoelectrical properties and thermal/chemical robustness. Highly flexible and efficient metal halide perovskite solar cells were fabricated on the films. The devices on the c-ITO/AgNW-and c-ITO/CuNW-GFRHybrimer films exhibited power conversion efficiency values of 14.15% and 12.95%, respectively. A synergetic combination of the thin c-ITO layer and the metal NW mesh transparent conducting electrode will be beneficial for use in flexible optoelectronic applications.

Flexible transparent conductive films (TCFs) are used in a variety of optoelectronic devices. However, their use is limited due to poor thermostability. We report hybrid TCFs incorporation in both aluminum-doped zinc oxide (AZO) and silver nanowires (AgNWs). The layered AZO/AgNWs/AZO structure was deposited onto a transparent polyimide (PI) substrate and displayed excellent thermostability. When heated to 250 °C for 1 h, the change in resistivity (Rc) was less than 10% (Rc of pure AgNW film > 500) while retaining good photoelectric properties (Rsh = 8.6 Ohm/sq and T = 74.4%). Layering the AgNW network between AZO films decreased the surface roughness (Rrms < 8 nm) and enhances the mechanical flexibility of the hybrid films. The combination of these characteristics makes the hybrid film an excellent candidate for substrates of novel flexible optoelectronic devices which require high-temperature processing.

“…Metal nanowires networks maintain the advantages of patterned metal films adding simpler and lower cost manufacturing available with solution-based deposited techniques. Moreover, IZO coating works as corrosion inhibitor to prevent the slow degradation of the silver nanowire film conductivity over time, whilst also improving nanowire adhesion to substrate and electrical connectivity of the network (Lee et al, 2013;Yun et al, 2016). Therefore, the motivation for this work comes from the need to explore emerging materials to advance transparent ECoG electrodes enabling new combinations of electrophysiology and imaging.…”

This work explored hybrid films of silver nanowires (AgNWs) with indium-doped zinc oxide (IZO) for developing high-performance and low-cost electrocorticography (ECoG) electrodes.The hybrid films achieved a sheet resistance of 6 Ω/sq while maintaining a transparency of ≈60% at 550 nm. Electrodes with 500 μm diameter were fabricated with these films and reached an impedance of 20 kΩ at 1 kHz and a charge storage capacity of 3.2 mC/cm 2 , a 2× and 320× improvement over IZO electrodes, respectively. Characterization of light-induced artifacts was performed showing that small light intensities (<14 mW/mm 2 ) elicit electrical potential variation in the magnitude order of baseline noise. The validation of electrodes in vivo was achieved by recording electrical neural activity from the surface of rat cortex under anaesthesia. Moreover, the presence of the films did not cause obstruction of light during fluorescence microscopy.The presented film and electrode characterization studies highlighted the capabilities of this hybrid structure to fabricate transparent and flexible electrodes that are able to combine the superior temporal resolution of extracellular electrophysiology with the spatial resolution offered by optical imaging.
