Optoelectronic performance of AgNW transparent conductive films with different width-to-height ratios and a figure of merit embodying an optical haze

Abstract

Transparent conductive films (TCFs) based on rectangularly shaped silver nanowires (AgNWs) with different width-to-height ratios were theoretically studied. We show that tall AgNWs (height > width) possess higher transmittance and lower sheet resistance compared to other configurations of AgNWs. Moreover, tall AgNWs possesses significantly higher optical haze, which makes them a transparent conductor of choice for thin solar cell applications. For applications requiring low haze such as displays and touch screens, we propose an updated figure of merit embodying transmittance, sheet resistance and haze, allowing tuning width-to-height ratio to achieve a reasonable AgNW TCF performance trade-off. Obtained results offer a means for deeper analysis of AgNW properties for many optoelectronic applications.

“…where T F is the forward transmitted light into the substrate through Ag NWs, and equal to T F = T T − T S . T T is the total light transmitted into the substrate through AgNW film and T S is the light scattered from AgNWs into the substrate [35].…”
