Transparent electrodes with nanorings: A computational point of view

Abstract

Four samples of transparent conductive films with different numbers of silver nanorings per unit area were produced. The sheet resistance, transparency, and haze were measured for each sample. Using Monte Carlo simulation, we studied the electrical conductivity of random resistor networks produced by the random deposition of the conducting rings onto the substrate. Both systems of equal-sized rings, and systems with rings of different sizes were simulated. Our simulations demonstrated the linear dependence of the electrical conductivity on the number of rings per unit area. Size dispersity decreased the percolation threshold, but without having any other significant effect on the behavior of the electrical conductance. Analytical estimations obtained for dense systems of equal-sized conductive rings were consistent with the simulations.

Flexible transparent electrodes based on metallic micro–nano architectures for perovskite solar cells

“…Azani et al developed a solvothermal method to synthesise silver nanorings. 142,143 When the pressure of the reactor increased to 150 kPa, 90% of the reduction product was silver nanorings as shown in Fig. 2c.…”

“…Random MMNAs. Random MMNAs usually include four different morphologies: nanoparticles (NPs), 137 nanowires (NWs), 126,127,[138][139][140][141] nanorings (NRs), 142,143 and random grids 46 (as shown in Fig. 2).…”

Benefits, Problems, and Solutions of Silver Nanowire Transparent Conductive Electrodes in Indium Tin Oxide (ITO)‐Free Flexible Solar Cells

“…Recently, the fabrication of TCEs using metal nanowire/nanorings, with performances comparable to those of ITO electrodes, has received increased attention. [ 90,91 ] Several research groups have used metal nanowires, such as silver, [ 92 ] gold, [ 93 ] and copper [ 94 ] to fabricate TCEs. The advantages of this group are not limited to the comparable optoelectronic performances with ITO electrodes; in fact, their simple synthetic methods, solution method processing, compatibility with various wet coating methods, and the feasibility of formulating AgNW conductive ink with water as an eco‐friendly solvent, are, among others, highly advantageous attributes in the fabrication process of TCEs.…”

“…Among them, hybrid electrodes comprising AgNWs‐graphene oxide (GO) and AgNWs‐mono layer graphene (MLG) from CVD have been widely investigated and applied to numerous optoelectronic devices. [ 15–167 ] As shown in Table 4, significant surface‐roughness reduction by applying these materials is achievable. The GO dispersion induced...…”

Silver Nanorings Fabricated by Glycerol-Based Cosolvent Polyol Method

“…It showed high flexible performance with little effect on light transmission and also exhibited some attractive properties to be applied in optical nanoantennae, plasmonic devices, and optical manipulation [20,21]. Azani et al simulated random networks deposited with conductive rings or wires and declared that AgNR can reach better optoelectrical property than AgNW at the same sheet resistance [22]. AgNR retains intrinsic chemical stability and low electrical resistivity like other silver materials and has strong localized surface plasmon resonance (LSPR) [23] to be used in energy conversion or signal enhancement.…”
