All-in-One Gel-Based Electrochromic Devices: Strengths and Recent Developments
Electrochromic devices (ECDs) have aroused great interest because of their potential applicability in displays and smart systems, including windows, rearview mirrors, and helmet visors. In the last decades, different device structures and materials have been proposed to meet the requirements of comm...
