Improved Coloration Effi ciency and Stability of WO 3 Electrochromic Devices by the Addition of Silver Nanowires
Abstract
WO 3 is one of the most studied electrochromic materials due to its high coloration effi ciency, strong cycling stability, and
low price. Those advantages make WO 3 ECD attractive to applications needing optical modulation, including smart windows
and smart glasses. However, due to market demands for reduced manufacturing and operating costs, demands for improved
coloration effi ciency and long-term stability have been continuously raised. In this study, we attempted to improve the contact
between WO 3 nanoparticles and Li ions and electrons by forming a nanocomposite electrochromic layer of WO 3 nanoparticles
and silver nanowires. It was confi rmed that this not only improves optical modulation and coloration effi ciency but also
improves stability. WO 3 electrochromic devices with improved coloration effi ciency and stability are expected to improve the
performance of existing smart windows and smart glasses and be applicable to new applications such as virtual reality glasses.
