A Redox-Flow Electrochromic Window

Michael Graetzel, Shaik Mohammed Zakeeruddin

A low-cost electrochromic (EC) window based on a redox-flow system that does not require expensive transparent conductive oxide (TCO) substrates is introduced and demonstrated for the first time. An aqueous I-3/I redox electrolyte is used in place of a TCO ...
