This invention relates to an electrically controllable solar building pane composed of two panels spaced apart by a layer of an intermediate gas, the panel facing towards the outside of the building being constituted of a variable transmission system of the electrochromic type comprising two transparent substrates composed, notably, of glass sheets, joined together by an ion-conducting organic polymer and coated on the jointing face with transparent electrically conducting films and films of anodic and cathodic electrochromic materials.

A method is provided for generating one or more differentiated zones of electrical conductivity or infrared emissivity in a thin semi-conducting layer of metallic oxide or oxides, comprising:

Process for the treatment of thin films having properties of electrical

An electrochromic variable transmission glazing comprising first and second glass sheets substrates which are joined by an organic polymer whose proton conductivity is greater than or equal to 10.sup.-5 ohm.sup.-1 cm.sup.-1 at 20.degree. C. The glass sheets are coated on their joining faces with transparent electroconductive layers. The first transparent substrate further comprises a layer of electrochromic material, such as tungsten oxide, in contact with the proton conductive polymer. The glazing is characterized by an iridium oxide layer on the second transparent substrate which is interposed between the layer of electroconductive material and the organic polymer. The glazing further comprises a pair of current leads attached to the electroconductive layer which connect the glazing to a generator.

Electrochromic variable transmission glazing

The invention pertains to an electrochromic system composed of a lithium ionic conductor electrolyte and a counter electrode symmetrical with the principal layer of electrochromic material and composed of a layer of nickel oxide, preferably deposited by reactive cathode sputtering in the presence of hydrogen-bearing plasma. The invention is used in particular for electrochromic windows, which can be used, for example, in automobile tops.
