ELECTROCHROMIC DEVICE USED AS ELECTROCHROMIC WINDOW OR PIXEL AND USE OF SAID DEVIC

The present invention relates to an electrochromic device (ECD) with a structure having five types of layers: a substrate (1), an electronic conductor (2), a primary electrochromic layer (3), an ion conductor (4) and an ion storage layer and/or complementary electrochromic layer (5). The invention also relates to the use of said device. The electrochromic device preferably has two main colours: green and yellow, depending on the colour combination seen through the layers. The present invention relates to two types of use of the electrochromic device, the first type consisting of a single pixel, among a plurality of pixels, and the second type relating to a single device used as an electrochromic window.
