Abstract
) to maintain the colored state. Moreover, we successfully demonstrate solar heat shutters that suppress the increment of indoor temperature by taking the advantage of low-power operation and near-IR absorption of the colored poly-viologen-based ECDs. Overall, these results imply that the control of the diffusivity of EC chromophores is an effective methodology for achieving single-layered, low-power electrochemical heat shutters that can save indoor cooling energy when applied as smart windows for buildings or vehicles.
