Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. An electrochromic device comprising: a lower transparent conductive layer, a first portion of said lower transparent conductive layer coupled to a first conductive element and a second portion, physically separate from the first portion, of said lower transparent conductive layer coupled to a second conductive element; a upper transparent conductive layer, a first portion of said upper transparent conductive layer coupled to the first conductive elem…
