First Claim
Patent Images
1. A method of depositing coatings for electrochromic devices comprising the steps of:
- providing a light transmissive substrate;
depositing on thermal vapor deposition a first light transmissive electrically-conductive material on said substrate;
depositing of thermal vapor deposition an electrochromic material upon said first electrically-conductive material while subjecting said substrate to an ion beam;
depositing by thermal vapor deposition an electron resistive-ion conductive material on said electrochromic material;
depositing by thermal vapor deposition an ion resistive-electron conductive material on said electron resistive-ion conductive material; and
depositing by thermal vapor deposition a second light transmissive electrically-conductive material on said ion resistive-electron conductive material to form an electrochromic device.

Abstract
Thin film coatings for solid state storage batteries and electrochromic energy conservation devices are now formed on low temperature glass and plastic substrates by an ion-assisted RF deposition process. The attachment of such coated glass or plastic substrates to existing windows in situ allows ordinary plate glass windows in homes, office buildings and factories to be converted to "smart-windows" resulting in a substantial savings in heating and air conditioning costs.
