Abstract

Films of tungsten-doped nickel oxide, denoted Ni_1-xW_x oxide as counter electrode in electrochromic devices were deposited onto indium tin oxide coated glass substrates by reactive dc magnetron sputtering using tungsten-doped nickel alloy target. Electrochromic properties of Ni_xW_1-x oxides were evaluated in lithium perchlorate in propylene carbonate. Enhanced cycle stability with moderate optical modulation was obtained for Ni_1-xW_x oxide film with x = 0.024. Significant degradation in pure NiO film during extended electrochemical cycling caused by microstructural deep trap sites was minimized by W doping. The EC device fabricated with WO₃ thin film and Ni_1-xW_x oxide thin film with x = 0.024 showed stable optical modulation of about 2% reduction from 100 to 1000 cycles. Flexible EC device was also fabricated with WO₃ thin film and Ni_1-xW_x oxide thin film with x = 0.024 deposited on c-ITO/graphene/PET electrode and showed stable cycling performance with maintaining optical modulation of ΔT ≈ 40%.
