Electrochromic variable transmission window

Abstract

Abstract A window comprising two transparent substrates, constituted especially by glass sheets (1, 2), assembled by an organic polymer (3), of which the protonic conductivity at 20 DEG C is not less than 10<-><5> ohm<-><1>.cm<-><1>, and clad over the assembly faces with transparent electroconductive layers (4, 5), the transparent substrate (1) furthermore comprising a layer (6) of electrochromic material, especially tungsten oxide, in contact with the protonic conductive polymer (4), the said glazing being characterised in that the second transparent substrate (2) also comprises an iridium oxide layer (7), symmetrical with the layer of electrochromic material (6) in relation to the organic polymer (3). <IMAGE>
