Electrochromic light valve and process for its production and application of the same
Abstract
The invention relates to an electrochromic light valve comprising an optically active electrochromic layer and an optically passive electrochromic layer. An electrolyte is provided between the two electrochromic layers. Each of the electrochromic layers is connected to an electrode assigned to it. The optically active electrochromic layer can be immersed and extracted by receiving electrons from its electrode and ions of a predetermined element from the electrolyte. The optically passive electrochromic layer forms a reservoir for identical ions of the predetermined element by emitting such ions to the electrolyte and receiving such ions from the electrolyte. The optically passive layer is oversaturated at the operating temperature of the electrochromic light valve with the element which supplies the identical ions. Moreover, the invention also presents a process for the manufacture of said electrochromic light valve and an application for the same.
