Thin layers forming an active colouring electrode in an electrochromic cell, in particular in electrochromic glass for use in buildings and vehicles, are produced by vacuum evaporation of metal oxides in an apparatus in which the flow of the vapour to the substrate to be coated follows a path that avoids any direct contact with the electrical resistances providing the heat required for evaporation, so as to obtain said thin layers in a stoichiometric composition with respect to the ideal formula of the evaporated oxide; this gives the highest colouring efficiency in the cell.
