Transparent Electronics: All‐Solution‐Processed Indium‐Free Transparent Composite Electrodes based on Ag Nanowire and Metal Oxide for Thin‐Film Solar Cells (Adv. Funct. Mater. 17/2014)

Abstract

A composite transparent composite electrode using silver nanowire (AgNW) with sol–gel derived ZnO and AZO is proposed by J. Moon and co‐workers with careful analysis of the electrical conduction behavior using conductive‐atomic force microscopy. On page 2462, low temperature (≈200 °C) processes are achieved by a combustion reaction based sol‐gel method, demonstrating a comparable performance to the sputtered ITO based device.

AlGaInP LED with low-speed spin-coating silver nanowires as transparent conductive layer

“…Transparent conductive layer (TCL) is crucial for light-emitting diodes (LEDs) which spread the carriers far away from the opaque electrodes to enhance the quantum efficiency and improve the efficiency droop effect [ 1 – 3 ]. Indium-doped tin oxide (ITO) material is widely used in LED field with the sheet resistance R s of 10 to 30 Ω/sq and optical transmittance T of 90%, which are two important figures of merit (FoM) to facilitate to describe the performance of TCLs [ 4 ].…”
