Definitions

  • the invention relates to a method for producing an electrochromic device, an electrochromic device and insulating glazing.
  • One type of modern, active glazing is glazing with switchable or controllable optical properties.
  • the transmission of light can be actively influenced as a function of an applied electrical voltage.
  • the user can switch the glazing from a transparent to an opaque state in order to prevent a view into a room from the outside.
  • the transmission can be infinitely adjusted, for example to regulate the entry of solar energy into a room. This avoids unwanted heating of buildings or vehicle interiors and reduces the energy consumption or CC>2 emissions caused by air conditioning systems.
  • Active glazing is therefore not only used for the visually appealing design of facades and a pleasant lighting design in interior rooms, but is also advantageous from an energetic and ecological point of view.
  • Electrochromic glazings are known, for example, from US 2012/0026573 A1 and WO 2012/007334 A1 as well as WO 2017/102900 A1.
  • Electrochromic glazing comprises at least one electrochemically active layer that is capable of reversibly storing charges.
  • the oxidation states in the stored and stored state differ in their coloring, with one of these states being transparent.
  • the storage reaction can be controlled via the externally applied potential difference.
  • the basic structure of the electrochromic glazing thus comprises at least one electrochromic material, such as tungsten oxide, which is in contact with both a surface electrode and a charge source, such as an ion-conductive electrolyte.
  • the electrochromic layer structure contains a counter-electrode, which is also capable of reversibly storing cations and is in contact with the ion-conductive electrolyte, as well as a further surface electrode which is connected to the counter-electrode.
  • the surface electrodes are connected to an external voltage source, whereby the voltage applied to the active layer can be regulated.
  • the surface electrodes are usually thin layers of electrically conductive material, often indium tin oxide (ITO). At least one of the surface electrodes is often applied directly to the surface of one of the individual panes of the laminated glass, for example by means of cathode atomization (sputtering).
  • Known insulating glazing is made from at least two panes which are connected to one another by at least one circumferential spacer.
  • the space between the two panes which is referred to as the glazing interior, is filled with air or gas.
  • insulating glazing can also contain other elements in the form of built-in components or panes with controllable additional functions.
  • One type of modern, active glazing is glazing with switchable or controllable optical properties. Such is known, for example, from EP 3 702 572 A1.
  • the transmission of light can be actively influenced as a function of an applied electrical voltage.
  • the user can switch the glazing from a transparent to a non-transparent state in order to prevent a view into a room from the outside.
  • the active glazing contains a functional element, which contains an active layer between two surface electrodes.
  • the optical properties of the active layer can be changed by applying a voltage to the surface electrodes.
  • Electrochromic functional elements are used in building construction in particular to shade large glass surfaces and to prevent people inside the building from being dazzled by solar radiation.
  • the transmission of visible light through the electrochromic functional element can be controlled by a voltage applied to the functional element. Voltage is supplied via so-called bus bars, which are usually applied to the surface electrodes and are connected to a voltage source via suitable connecting cables.
  • EP 2 841 987 B1 discloses a method for circumferential sealing of an electrochromic element with a primary sealant.
  • US 2009/0284821 A1 describes a method for producing electrochromic glazing, in which the risk of short circuits and fault currents is to be minimized.
  • an insulating glazing shown in FIG. 1 comprises a first pane 102 and a second pane 104.
  • the first pane 102 has a first surface 102.1 and a second surface 102.2.
  • the second disk 104 has a first surface 104.2 and a second surface 104.2.
  • the first surface 104.1 of the second disk 104 and the second surface 102.2 of the first disk 102 face each other and a spacer 106 is arranged between these surfaces.
  • the area between the first pane 102 and the second pane 104 is provided with a seal 110 outside of the spacer 106 .
  • an electrochromic device 1 which has a substrate and an electrochromic element 3, is arranged on the second surface 102.2 of the first pane 102.
  • the substrate 2 is laminated with its first surface 2.1 via a composite film 114 on the second side 102.2 of the first pane 102.
  • the multilayer electrochromic element 3 is arranged on the second side 2.2 of the substrate 2.
  • FIG. The electrochromic element 3 has two contacts designed as a bus bar 14 , 16 .
  • a blackout strip 116 is applied to the second side of the first pane.
  • first electrically conductive layer 6 followed by an insulating layer 10 and an active layer 4 are deposited on the substrate 2 .
  • the active layer 4 comprises electrochromic material.
  • the layer stack produced in this way is shown in FIG. 2a).
  • first recesses P1 are cut, in particular by means of a laser. These recesses extend over the first electrically conductive layer 6, the first insulating layer 10 and the active layer 4 and are shown in FIG. 2b.
  • the size of the active area of the electrochromic element 3 is defined by the introduction of the recesses P1.
  • a second insulating layer 12 and a second electrically conductive layer 8 are subsequently deposited. The second insulating layer 12 and the second electrically conductive layer 8 also extend into the recesses P1, as shown in FIG. 2c.

  • the second electrically conductive layer is then removed by means of the recess P3 at a predetermined point in such a way that the first busbar contacts the first conductive layer and the second busbar contacts the second conductive layer contacted.
  • a disadvantage of the above method is that the shape and size of the electrochromic device is already fixed before the start of the deposition process and structuring process. As a result, the production process for the electrochromic device and also for corresponding devices becomes inflexible and the corresponding production times long, which also increases the production costs, among other things.
