“…Among these, silver nanowire (AgNW) electrodes are recognized as the most promising owing to their high light transmittance, low sheet resistance, good processability, and excellent flexibility. [ 17,29 ] Both bottom [ 28–31 ] and top [ 32–34 ] electrodes using AgNW networks have been reported in polymer and perovskite solar cells. However, in terms of the FTE for PSCs, only a few studies have been conducted, [ 2,17,35–37 ] and these AgNW films were prepared by spin coating [ 2,36,37 ] or slot‐die coating.…”

With the aim of developing high‐performance flexible polymer solar cells, the preparation of flexible transparent electrodes (FTEs) via a high‐throughput gravure printing process is reported. By varying the blend ratio of the mixture solvent and the concentration of the silver nanowire (AgNW) inks, the surface tension, volatilization rate, and viscosity of the AgNW ink can be tuned to meet the requirements of gravure printing process. Following this method, uniformly printed AgNW films are prepared. Highly conductive FTEs with a sheet resistance of 10.8 Ω sq−1 and a high transparency of 95.4% (excluded substrate) are achieved, which are comparable to those of indium tin oxide electrode. In comparison with the spin‐coating process, the gravure printing process exhibits advantages of the ease of large‐area fabrication and improved uniformity, which are attributed to better ink droplet distribution over the substrate. 0.04 cm2 polymer solar cells based on gravure‐printed AgNW electrodes with PM6:Y6 as the photoactive layer show the highest power conversion efficiency (PCE) of 15.28% with an average PCE of 14.75 ± 0.35%. Owing to the good uniformity of the gravure‐printed AgNW electrode, the highest PCE of 13.61% is achieved for 1 cm2 polymer solar cells based on the gravure‐printed FTEs.

“…Previously, several studies have successfully demonstrated that the silver nanowires can be applied as the top semitransparent electrodes in single‐junction organic solar cells, [ 31–35 ] tandem organic solar cells, [ 36,37 ] and also perovskite solar cells. [ 38–40 ] Our work aims to explore a low‐cost, scalable, and facile all‐solution processing AgNWs‐based transparent top electrode for efficient ST‐OPVs without any damage to the photoactive layer. To underline the significance of this work, Table S1, Supporting Information, summarizes the photovoltaic performance and optical property of ST‐OPVs with all‐solution processed top electrodes in the past several years.…”

Semitransparent organic photovoltaics (ST-OPVs) provide a potentially facile route for some applications in building integrated photovoltaics. One of the challenges in developing large-scale, printable ST-OPVs is to address the need for highperformance and fully solution-processed top electrodes, allowing the replacement of the evaporated thin metallic films (Ag, Au, and Al). Silver nanowire (AgNW) is considered a promising candidate for the substitution due to its excellent transparency, conductivity, and solution processability. Herein, a novel bimodal AgNW (AgNW-BM) electrode is reported, comprising AgNWs of two different aspect ratios. It is shown that the AgNW-BM film achieves lower sheet resistance and higher visible transmittance than each monodisperse AgNW film, respectively. Furthermore, ST-OPVs based on PTB7-Th:IEICO-4F with AgNW-BM top electrodes are fabricated, which can obtain a maximum power conversion efficiency (PCE) of 7.49% with an average visible transmittance (AVT) of 33%. The ST-devices also demonstrate an enhanced reproducibility and excellent color-rendering index of 90. In addition, the bimodal top electrode is successfully implemented in the PM6:Y6 system with a higher PCE of 9.79% and with an AVT of 23%, demonstrating the universality for various semiconductor systems. Our work provides a simple strategy to realize fully solution-processed, highly efficient ST-OPVs.
