Abstract
Official abstract text for this publication.
A multi-layer device comprising a first substrate and a first electrically conductive layer on a surface thereof, the first electrically conductive layer having a sheet resistance to the flow of electrical current through the first electrically conductive layer that varies as a function of position.
First claim
Opening claim text (preview).
What is claimed is: 1 . A method of forming an electrochromic multilayer stack comprising: providing a first substrate comprising a first transparent electrically conductive layer; patterning the first transparent electrically conductive layer with laser patterning to form a patterned first transparent electrically conductive layer having a first spatially varying resistance to the flow of electrical current through the first transparent electrically conductive layer that varies as a function of position in the first transparent electrically conductive layer; and forming a first electrode layer comprising an electrochromic material over the patterned first transparent electrically conductive layer. 2 . The method of claim 1 , wherein patterning the first transparent electrically conductive layer comprises laser patterning a series of laser scribes. 3 . The method of claim 1 , wherein depositing the first transparent electrically conductive layer on the substrate comprises forming a film having a constant thickness and a constant resistivity. 4 . The method of claim 1 , wherein patterning the first transparent electrically conductive layer varies the first spatially varying resistance such that a ratio of a value of a maximum sheet resistance to a value of minimum sheet resistance in the first electrically conductive layer is at least 10. 5 . The method of claim 1 , further comprising: providing a second substrate comprising a second transparent electrically conductive layer and patterning the second transparent electrically conductive layer with laser patterning to form a patterned second transparent electrically conductive layer having a second spatially varying resistance to the flow of electrical current through the second transparent electrically conductive layer that varies as a function of position in the second transparent electrically conductive layer; forming a second electrode layer over the patterned second transparent electrically conductive layer; forming an ion conductor layer between the first and the second electrode layers to form an electrochromic multilayer device. 6 . The method of claim 5 , wherein the first spatially varying resistance varies as a function of position opposite to that of the second spatially varying resistance.
