This invention focuses on electrooptic devices and in particular on electrochromic devices with many aspects directed towards automotive EC mirrors. There are several ways to improve these products and their processing using this invention and some of the prominent ones are outlined below. This invention improves on the devices by disclosing new compositions for electrodes and methods of depositing them. It also addresses novel ways to provide busbars to power these devices in order to improve their performance. The device processing attributes and performance are also improved by adhesive compositions and solid electrolytes disclosed herein. In addition sensors are also disclosed which are novel for use in electrochromic mirrors. The invention also discloses how the electrolytes comprising ionic liquids have no adverse effect on attributes of commercial EC mirrors and often result in improved performance and/or feature enhancements.
