摘　　要：Transparent electrodes(TEs)with high chemical stability and excellent flexibility are critical for flexible optoelectronic devices,such as photodetectors,solar cells,and light-emitting diodes.Ultrathin metal electrode(thickness less than 20 nm)has been a promising TE candidate,but the fabrication can only be realized by vacuum-based technologies to date,and require tedious surface engineering of the substrates,which are neither ideal for polymeric based flexible applications nor suitable for roll-to-roll large-scale manufacture.This paper presents high-performance nanostructured transparent metal electrodes formation via displacement-diffusion-etch(DDE)process,which enables the solution-processed sub-20-nm-thick ultrathin gold electrodes(UTAuEs)on a wide variety of hard and soft substrates.UTAuEs fabricated on flexible polyethylene terephthalate(PET)substrates show a high chemical/environmental stability and superior bendability to commercial flexible indiumtin-oxide(ITO)electrodes.Moreover,flexible organic solar cells made with UTAuEs show similar power conversion efficiency but much enhanced flexibility,in comparison to that of ITO-based devices.
