“…37 This supports our conclusion that the growth of the Au-rich regions is due to the surface diffusion of Au atoms after segregation to the surface through the channels of reduced Fe thickness. However, the segregation through the cracks is possibly not the only mechanism of Au segregation.…”

“…That way the system increases the adlayer substrate binding which overbalances the cost of removing a substrate row. 45 The resulting troughs at the surface are well localized and can serve as diffusion channels to built up equally spaced 1D islands by self-organized growth.…”

“…This gives E m ÁV ÁU vib . Dynamic, temperature dependent values of the barrier are typically inferred from molecular dynamics simulations [45,46], or within harmonic approximations for the lattice dynamics [47]. At low temperatures, ÁU vib is small compared to ÁV, so for many purposes it suf®ces to assume E m to be temperature independent, and to assign it with the static barrier.…”

Solution‐processed metal nanowire networks have attracted substantial attention as clear transparent conductive electrodes (TCEs) to replace metal oxides for low‐cost and flexible touch panels and displays. While targeting photovoltaic applications, TCEs are expected to be more hazy for enhancing light absorption in the active layer, but are still required to retain high transmittance and low sheet resistance. Balancing these properties (haze, transmittance, and conductivity) in TCEs to realize high performance but high haze simultaneously is a challenge because they are mutually influenced. Here, by precisely tailoring the diameter of thick–long silver nanowires using rapid radial electrochemical etching, high hazy flexible TCEs are fabricated with high figure of merit of up to 741 (4 Ω sq−1 at 88.4% transmittance with haze of 13.3%), surpassing those of commercialized brittle hazy metal oxides and exhibiting superiority for photovoltaic applications. Laminating such TCEs onto the perovskite solar cells as top electrodes, the obtained semitransparent devices exhibit power efficiencies up to 16.03% and 11.12% when illuminated from the bottom and top sides, respectively, outperforming reported results based on similar device architecture. This study provides a simple strategy for flexible and hazy TCEs fabrication, which is compatible with mild solution‐processed photovoltaic devices, especially those containing heat‐sensitive or chemical‐sensitive materials.
