Abstract: Electrochromic devices with reflective structure and related manufacturing methods are provided. One of the electrochromic devices includes a bottom electrode layer, an electrochromic layer on the bottom electrode layer, an electrolyte layer on the electrochromic layer, a charge storage layer on the electrolyte layer, and a top electrode on the charge storage layer. The transmittance of the electrochromic device changes in response to a voltage applied between the bottom electrode layer and the top electrode layer. One of the bottom and the top electrode layers is a reflective conductive layer, while the other being a transparent conductive layer. This electrochromic device has a simplified structure due to the removal of a separated reflective film, which also results in simplified manufacturing process.
