Abstract
An electrochromic device is disclosed having a selective ion transport layer which separates an electrochemically active material from an electrolyte containing a redox active material. The devices are particularly useful as large area architectural and automotive glazings due to there reduced back reaction.
Claims43
An electrochromic device comprising a conducting electrode opposing a counter electrode with (i) an electrochemically active material layer, (ii) a selective ion transport layer and (iii) an electrolyte containing at least one redox active material, wherein said electrochemically active material layer, said selective ion transport layer and said electrolyte are sequentially disposed between said conducting electrode and said counter conducting electrode and at least one of said electrodes is transparent.
