  • Patent number: 9013778
    Abstract: One object of the present invention is to provide an electrochromic device having improved insulating film structure to reduce electrical leakage. The improved structure includes a lower conductive layer, upper conductive layer, an electrochromic electrode layer, a counter electrode layer, and at least one ion-conductor layer sandwiched between the electrochromic electrode layer and the counter electrode layer. The lower conductive layer and the electrochromic electrode layer are scribed and the gap formed from the scribing is filled with the layers formed above the electrochromic electrode layer. In some aspects, the ion-conductor layer is also scribed with the lower conductor and electrochromic electrode layers and the gap formed from the scribing is filled with the layers formed above the ion-conductor layer. In further aspects, the insulating film may include one or more buffer layers formed above an ion-conductor layer, further separating the upper conductive layer from the lower conductive layer.

  • Publication number: 20150029573
    Abstract: One object of the present invention is to provide an electrochromic device having improved insulating film structure to reduce electrical leakage. The improved structure includes a lower conductive layer, upper transparent conductive layer, an electrochromic electrode layer, a counter electrode layer, and at least one ion-conductor layer sandwiched between the electrochromic electrode layer and the counter electrode layer. The lower transport conductive layer is scribed and the gap formed from the scribing is filled with the layer(s) formed above the lower conductive layer, such as the electrode layer formed directly above the lower conductive layer. The effective linewidth of the scribe is greater than the migration length of the lithium ions intercalated into the electrode layer, such that the electrode materials occupying the gap do not convert the electrode layer into an electrically conductive region.

  • Patent number: 8282997
    Abstract: The invention concerns a method for producing a coating on a support, in particular a glass support, wherein a thin-film metal oxide is deposited on the support, said thin film being subjected to an etching process to roughen its surface, a second coating capable of adhering to the first metal oxide film is then applied on the roughened surface. The invention is characterized in that it consists in depositing a first doped metal oxide or metal oxynitride doped with at least a second metal oxide or metal oxynitride, the second metal oxide or metal oxynitride being distributed in the deposited film. During the etching process, a plasma-activated gas is used which removes at least a second metal oxide or metal oxynitride less than the first metal oxide or metal oxynitride so as to form, after the etching process, on the surface raised irregularities consisting of at least a second metal oxide or metal oxynitride.
