Electrochromic layer structure and method for the production thereof

Abstract

An electrochromic layer structure with at least one active layer (100) and at least two electrodes (102; 104) is described. At least one of the electrodes (102; 104) has an electrically conductive network (110; 202) of conductor tracks and the conductor tracks contain nanoparticles (300). An electrochromic device, a method for production of an electrochromic layer structure and use of an electrochromic layer structure and an electrochromic device are also described.

Description

technical field

[0001] The present invention relates to electrochromic layer structures, electrochromic devices, methods for manufacturing electrochromic layer structures and applications of electrochromic layer structures and electrochromic devices. Background technique

[0002] Windows are important components in buildings. Previously, window panes were only used for the purpose of looking out freely, whereas today there are significantly higher demands on glazing. On the one hand, the vitrified area should serve for ideal thermal insulation of the interior, but on the other hand it should also ensure that the interior is only heated to the desired extent by the glazing when exposed to the sun. The possible control of the light incidence by means of glazing can be adjusted, for example, by means of movable shutters. Another possibility is provided by glazing that changes its optical properties such as transparency and reflectivity when a button is pressed or independentl...

The electrochromic layer structure comprises an electrochromic active layer 100 embedded between two electrodes 102 and 104 . Furthermore, the electrodes 102 and 104 are each covered on the side facing away from the active layer by a transparent protective pane 106 and 108 . figure 1 The electrochromic layer structure can be an electrochromic layer structure with an inorganic solid electrolyte and the transparent protective plates 106 and 108 can be borosilicate glass.

[0057] The electrochromic control unit 112 serves as a transparency control of the active layer to incident light by applying a voltage between the electrodes 102 and 104 . Electrode 104 is an anode and electrode 102 is a cathode. Ion transport through the active layer 100, which comprises an ionically conductive po...
