Abstract

Patterned few nanometers thick silver films with high optical transparency, electrical conductivity, mechanical flexibility and stability.

Advances in Flexible Metallic Transparent Electrodes

“…These metal grids are the thinnest reported so far, and demonstrated a very uniform heating performance under bending into a roll, as shown in Figure 14b. [ 398 ] As mentioned in Section 3.3.2, a core–shell nanofiber (NF) structure using coaxial electrospinning is an efficient approach for high‐temperature TEs. Indeed, material failure due to the atomic diffusion of metal atoms in nanomaterial‐based THs is a major concern that affects the lifetime of the device.…”

Greatly enhanced hole collection of MoOx with top sub-10 nm thick silver films for gridless and flexible crystalline silicon heterojunction solar cells

“…4b). Upon light illumination, localized surface plasmons (LSPs) are excited in either nanoparticles or nanoclusters, [57][58][59][60][61] resulting in enhanced absorption and thus transmission dips around 650 nm (Fig. S3, ESI †).…”

“…As a consequence of physical vapor deposition technology, the thermal evaporation of metal lms inevitably suffers from the three-dimensional (3D) Volmer-Weber growth mode in the initial stage of deposition. [57][58][59][60][61] A continuous lm with low resistance cannot be achieved with thickness below 10 nm. A thick lm will however lead to rather low optical transparency.…”

Fabrication of the Silver Grids by Interfacial Interaction

“…The fabricated Ag meshes/grids changed patterns by changing the size of Ag NPs and/or Ag nanowires. [35][36][37] Self-assembly combining with silicon pillar template is also a good method to fabricate Ag grids, which have been used as surface-enhanced Raman scattering or single molecule detection. However, the conductivity of Ag grids needs to be improved.…”
