摘要
Tantalum oxide (Ta2O5) thin films prepared by reactive magnetron sputtering are investigated for their potential use as the ionic conducting layer in all solid state monolithic electrochromic devices. The paper focuses on the influence of Ta2O5 coatings on the electrochromic response of amorphous tungsten oxide (a-WO3), the methods employed for charging during monolithic device fabrication and associated charge losses caused by subsequent deposition of the component layers of monolithic (all solid state) electrochromic devices. The dependence of the electrochromic response and related charge loss processes have been studied for Ta2O5 films of different thicknesses prepared on a-WO3 electrochromic films.
