“…Table 2 presents a comprehensive comparison among the flexible AgNW films. Compared with the AgNW films reported, whether by transfer 26,29,39,41,53 or direct-coating, 44,45 the AgNW/WA/PDMS film in this work exhibits a much better comprehensive performance. Besides higher FoM, it also has low surface roughness, better long-term stability and electrical stability simultaneously.…”

“…By comparison, the resistance of the AgNW film on glass increased 3.0%, 4.4%, 8.4% and 17.7%, respectively. It has been reported that the resistance of the direct-coated AgNW/PDMS film increased more than 15% after only 100 h, 48 or more than 60% after 13 days, 44 as well as a resistance increase of 50% after 20 days for the transferred AgNW/PDMS film 26 in air. Few studies reported the stability under electrical stress of flexible AgNW films.…”

“…15−17 However, the usage of composite films in the natural setting is constrained by the oxidative polymerization of PEDOT:PSS in water. 18 Noble metals have great stability and no corrosivity, and the shell layers of core− shell-structured NWs have been made of metals including Pt, 19−21 Au, 19,22 Ni, 23,24 and Pb. 25 However, metal shells frequently cause transmittance to degrade, and the electrochemical approach is less ecofriendly.…”

Silver nanowires (AgNWs) have received much attention from researchers for their superior optoelectronic properties and are thought to be the most potential substitute for indium−tin oxide. However, the poor stability of the AgNW network when exposed to the atmospheric environment for a long time is a pivotal problem. The surface of the AgNW is easily oxidized, and the NW scale is too small, accelerating the degradation mechanism of Ag, which is limited in practical applications. In this study, a simple and inexpensive solution approach is innovatively proposed to prepare ultrathin Ag@ZnO NW networks with core−shell structure to improve the thermal, electrical, and chemical stability of AgNWs. The formed Ag@ZnO NW network has a high transmission of 81% with a low sheet resistance of 7.5 Ω/sq. More importantly, the Ag@ZnO NW network can withstand high temperatures up to 280 °C without performance degradation. In addition, the Ag@ZnO NW network shows excellent thermal and chemical stability and maintains the original performance under harsh conditions such as high temperature, high relative humidity, ultraviolet ozone, strong oxidants (Na 2 S), and salinity (NaCl). Finally, the application of Ag@ZnO NW flexible transparent conductive electrodes (FTCEs) in an electrochromic device is successfully demonstrated to verify the applicability of Ag@ZnO NW FTCEs, and the electrochromic device has cyclability and quick responsiveness.

“…Nevertheless, the preparation process of ionic liquid is complicated. To improve the environmental stability of AgNW FTEs, a simple strategy is to coat AgNW films with additional protective materials such as PE-DOT:PSS, 23 metal oxides, 24 and biomaterials. 25 These materials generally have low transmittance in the visible region and show conductivity that is orders of magnitude lower than that of AgNWs, which inevitably affects the transmittance and conductivity of FTEs.…”

Silver nanowires (AgNWs) are important materials for flexible transparent electrodes (FTEs). However, the loose stacking of nanowire junctions greatly affects the electric conductivity across adjacent nanowires. Soldering can effectively reduce the wire−wire contact resistance of AgNWs by epitaxially depositing nanosolders at the junctions, but the process normally needs to be performed with high energy consumption. In this work, we proposed a simple room-temperature method to achieve precise welding of junctions by adjusting the wettability of the soldered precursor solution on the surfaces of AgNWs. The nanoscale welding at nanowire cross junctions forms efficient conductive networks. Furthermore, reduced graphene oxide (rGO) was used to improve the stability of FTEs by wrapping the rGO around the AgNW surface. The obtained FTE shows a figure-of-merit (FoM) of up to 439.3 (6.5 Ω/sq at a transmittance of 88%) and has significant bending stability and environmental and acidic stability. A flexible transparent heater was successfully constructed, which could reach up to 160 °C within a short response time (43 s) and exhibit excellent switching stability. When laminating this FTE onto half perovskite solar cells as the top electrodes, the obtained double-side devices achieved power conversion efficiencies as high as 16.15% and 13.91% from each side, pointing out a convenient method for fabricating double-sided photovoltaic devices.
