Enhancing light reflective properties on ITO glass by plasmonic effect of silver nanoparticles

The preparation of well-defined silver (Ag) nanoparticle arrays is reported in this paper. Ag nanoparticles are electrodeposited on Indium tin oxide (ITO) coated glass substrates at 30 degrees C. The size, shape and periodicity of the Ag nanoparticle arrays are well-controlled. We study the effect of particle size and interparticle distance on reflection enhancement. The sample at the deposition potential of -0.2 V for an electrodeposition time of 3600 s exhibits an enhancement of 28% in weighted reflection in contrast with bare ITO glass. This study reports the high reflection of Ag nanoparticle arrays by electrodeposition method might be application to large-scale photovoltaic devices. (C) 2017 The Authors. Published by Elsevier B.V.
