Abstract Electrochromic devices (ECDs) are attracting attention for their simple controllable optical modulation and potential energy saving abilities. When integrated with solar cells self-powering and smart energy management systems may be realized. However, their performance, especially the opaque colored state for privacy protection and energy saving, is still a problem for most devices. Here we demonstrate a vertically integrated approach for preparing cascade electrochromic devices (CECDs) with marked performance compared with ECDs. The cascade strategy allows for devices that simultaneously achieve highly opaque colored states with shorter optical response times, stores comparably higher energy density, whilst protecting the device from electrical cycling degradation associated with high current densities. Furthermore, the adaptive electrochromic energy saving units are integrated, which could be an innovative green energy manage technology and enabling wide applications for smart home and daily or special use.

一种可扩展和可调的全不透明级联智能电致变色器件

摘要 电致变色器件(ECD)因其简单可控的光调制和潜在的节能能力而备受关注。当与太阳能电池集成时,可以实现自供电和智能能源管理系统。然而,它们的性能,尤其是用于隐私保护和节能的不透明着色状态,仍然是大多数设备的问题。在这里,我们展示了一种垂直集成的方法,用于制备与 ECD 相比具有显着性能的级联电致变色器件 (CECD)。级联策略允许器件以更短的光学响应时间同时实现高度不透明的有色状态,存储相对更高的能量密度,同时保护器件免受与高电流密度相关的电循环退化。此外,
