Large-area electrochromic glazing with ion-conducting PVB interlayer and two complementary electrodeposited electrochromic layers

A new laminated large-area electrochromic glass consisting of two FTO-coated glass panes coated with complementary electrochromic thin films by electrodeposition and laminated together by the use of an ion-conducting PVB sheet is presented. The visible light transmittance can be changed between 77% and 8% and the solar transmittance between 56% and 6%.
