A Low Driving-Voltage Hybrid-Electrolyte Electrochromic Window with Only Ferreous Redox Couples.

ABSTRACT: Even after decades of development, the widespread application of electrochromic windows (ECW) is still seriously restricted by their high price and inadequate performance associated with structural/fabrication complexity and electrochemical instability. Herein, a simple hybrid electrochromic system based on PFSA (perfluorosulfonic acid)-coated Prussian blue (PB, Fe₄^III [Fe^II(CN)₆]₃) film and Ferricyanide-Ferrocyanide ([Fe(CN)₆]^4-/[Fe(CN)₆]^3-)-containing hybrid electrolyte is reported. The PB film and the [Fe(CN)₆]^4-/[Fe(CN)₆]^3- couple show near redox potentials well inside the electrochemical window of water, resulting in a low driven voltage (0.4 V
