“…Shi et al utilized nickel electroplating to simultaneously improve the conductivity and corrosion resistance of the AgNW network. 262 Subsequently, the SnO 2 quantum dots and sputtered ITO were further used to modify the transparent electrode. A PSC with a PCE of 18.37% and T 80 of 432 h was achieved.…”

“…28,30 That makes of variance a very interesting parameter for evaluating kinetics of electrochemical processes since this maximum proves a measurement of the half-life time for different processes. The resolution of this technique allows to distinguish (for 8 bit images) up to 2 24 colors and for each RGB coordinate we have 256 color levels, ranging from no color (black,0) to pure color (255). The resolution increases when analyzing a set of pixels, since for an image of 100 × 100 pixels an average value of 10000 pixels is calculated and we can detect average intensity changes of one hundredth of an RGB unit.…”

“…Passive layers can grow on the Ni metal surface due to their high reactivity and the nature of these passive layers is highly dependent on the pH of the electroplating solution. [20][21][22][23][24] Finally, there is the electrical resistance of the electroplating solution and the relative position of electrodes in the electrochemical cell which can cause non-ideal effects. 25 If electrodes were near enough, the ohmic drop of the solution was minimized but subproducts on the auxiliary electrode can reach the working electrode interfering in the electrochemical Ni 2+ reduction.…”

The quality of metal electrodeposits on different surfaces depends on the configuration and composition of the electrochemical bath, and on the control of experimental variables that can affect the electrode processes taking place. In this work, we have studied the electrodeposit of nickel on a polypropylene|graphite|copper (PP|G|Cu) ternary composite electrode. Together with the resistive behavior of the electrode, the nickel electrodeposition presents extra difficulties as a low reduction potential and numerous and possible chemical reactions with the medium to form passive layers or aqueous complexes. The use of digital video electrochemistry (DVEC) has allowed detection of some issues during the electrodeposition and electrodissolution processes such as the non-uniform growth of Ni due to the electrode configuration, secondary and oscillatory electrochemical reactions caused by the subproducts in the auxiliary electrode or the effect of the formation of hydrogen bubbles. The estimation of electrodeposition efficiency from DVEC and a possible electrodissolution mechanism are discussed.

“…It is reported that sulfidation is the main corrosion of AgNWs in the air 25 . In perovskite solar cells application, halide ions react with silver causing an increase in the resistance of nanowires 26 . The instability problem of AgNWs is still a major challenge that requires further studies to improve their stability 27 .…”

“…To address the stability issue of AgNWs, protective coatings have been used in previous studies. These coatings include metal oxides (MoO x 35 WO x 36 NiO 37 ZnO and Al 2 O 3 38 ), metals (palladium (Pd) 39 , nickel (Ni) 26 gold (Au) 40 – 42 ), graphene 43 , 44 , and polymers. Though these coatings can improve chemical stability, they may have negative effects on optoelectronic properties due to their low electrical conductivity like most metal oxides and polymers.…”

Silver nanowires (AgNWs) with a low diameter, high aspect ratio, stable suspension, and easy synthesis have recently attracted the optoelectronic industry as a low-cost alternative to indium tin oxide transparent conductive films. However, silver nanowires are not chemically stable, and their conductivity diminishes over time due to reactions with atmospheric components. This is a bottleneck for their wide industrial applications. In this study, we aim to address this issue by synthesizing silver nanowires with an average diameter of approximately 65 nm and a length of approximately 13 µm. The prepared Ag nanowires are then applied to fabricate transparent, flexible, and chemically stable conductive films. The fabrication includes spraying of silver nanowires suspension on a glass substrate followed by Dr. blade coating of polystyrene (PS) solution and delamination of the PS-AgNWs film. The resulting film exhibits an optimum sheet resistance of 24 Ω/□ and transmittance of 84%. To further enhance the stability of the transparent conductive film, the facial and scalable double pulse electrodeposition method is used for coating of gold on the exposed surface of the AgNWs embedded in PS. The final transparent film with gold coating demonstrates a remarkable stability under harsh conditions including long exposure to UV light and nitric acid solution. After 100 min of UV/Ozone treatment, the increase in sheet resistance of the optimal PS-AgNW@Au sample is 15.6 times lower than the samples without gold coating. In addition, the change in sheet resistance after 2000 bending cycles in the optimal PS-AgNW@Au electrode is measured and it showed an increase of only 22% of its initial sheet resistance indicating its good flexibility. The proposed electrode performs an excellent chemical stability, good conductivity, transparency, and flexibility that makes it a potential candidate for various optoelectronic devices.
