Abstract
The present invention is directed to method for manufacturing electrochromic devices using laser ablation techniques. More specifically, the present invention uses laser ablation to provide a simple, noncontact method of patterning electrochromic devices to a controlled depth, to form an electrochromically active area. Furthermore, laser patterning is conducive to the formation of multiple electrochromic devices on a single substrate.
