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.
