“…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.

“…), necessitates approaches to protect the metal/perovskite against degradation during cell fabrication. [98,235] Meanwhile, the migration/diffusion of both the halide ions [236] and metals (e.g., Ag or Au) [237,238] raises a series concern for the device stability over time. To partially circumvent these issues, a rational design decision is to investigate transparent metals as the top rather than the bottom electrodes in PSCs (less invasion of halides from their solution deposition).…”

Recent Progress on Emerging Transparent Metallic Electrodes for Flexible Organic and Perovskite Photovoltaics

The rapid development of smart and wearable electronics calls for revolutionizing optoelectronics to become flexible, lightweight, and affordable. To meet these demands in photovoltaic devices, that is, solar cells, it is essential to develop mechanically flexible transparent electrodes over the conventional rigid ones while features such as low‐temperature procedures, stability, solution process, and/or low cost are highly desired and often required. Moreover, the optoelectronic properties of an electrode must not be compromised in an operational flexible cell. Despite the considerable challenges, various bendable transparent electrodes for solar cells have emerged in recent years. Particularly, transparent electrodes based on metallic materials are especially attractive as metal offers excellent conductivity and their formation processing is generally mature and commercially viable. This work aims to provide an overview of the recent development of metal‐based transparent electrodes for flexible organic and perovskite photovoltaics. After the introduction, metallic materials for the transparent electrodes including nanowires, meshes/grids, and films are discussed. The procedures and protocols for cell flexibility testing are summarized, before highlighting recent progress on fully functional, high‐efficiency flexible organic and perovskite solar cells using these transparent metallic electrodes. Finally, the challenges and outlook of the research field are discussed.

“…The high quality of a decreased grain size perovskite film electrode could be attributed to light absorption and increasing the pinhole process for the optimization of commercial flexible PSCs [ 34 ]. Besides, zinc oxide-supported, Ag-NW-based flexible PSCs exhibited both optical and electrical properties, whereas the surface study of a flexible composite could decrease the surface roughness and significantly improved their remarkable flexible devices [ 35 ].…”
