Tungsten Oxide Film Applied for Electrochromic Window

Tungsten oxide film is designed to fabricate electrochromic window, which is also called smart window. Some researchers have adopted a spin-coating technique to deposit tungsten oxide (WO3) film by using sol-gel peroxotungstic acid sol. And the prepared tungsten oxide thin film was used to produce smart window.

In a report, glass/ FTO/ WO3/ electrolyte/ FTO/glass could be of use due to its special structure that consists of an electrochromic layer (WO3) on a transparent conductor (FTO), an electrolyte containing Li+ cations, and a transparent conductor layer. A voltage was applied on the fabricated sample, which was later assessed for its transmission, switching speed, and coloration efficiency. And it was found that an increase in the coloration efficiency was associated with an increase in the deposition speed. Moreover, the increase in the deposition speed led to a decrease in the coloration and bleaching time duration. In a word, the results obtained on the thin tungsten oxide film can be useful for electrochromic window applications.
