An electrochromic device is disclosed which has a plurality of layers, including at least one planarizing layer having an upper surface roughness which is less than or equal to half of the upper surface roughness of an underlying layer in contact with a lower surface of the at least one planarizing layer, wherein at least valleys of the underlying layer are filled by the lower surface of the at least one planarizing layer. A method for fabricating the electrochromic device is also disclosed.

Electrochromic devices and method for forming such devices

A deposition method includes: (1) providing a nozzle structure including: (a) at least one corona generator having an elongated charge emitting surface; and (b) at least one aerosol channel adapted to guide an aerosol along a flow path past the at least one corona generator; (2) generating an aerosol of a precursor solution; (3) applying to the at least one corona generator a positive or negative voltage of 1 kV-100 kV with respect to the substrate to generate a corona; and (4) flowing the aerosol through the at least one aerosol channel, along the flow path near the at least one corona generator and toward the surface of the substrate so as to charge the aerosol with ions emitted from the at least one corona generator to form charged droplets which are attracted to and deposited on the substrate, wherein the elongated charge emitting surface is a wire or blade edge, which is substantially parallel to the surface of the substrate and substantially perpendicular to the flow path, provided that the at least one corona generator does not consist of two blades. Inventive nozzle structures are also described.

Charge assisted spray deposition method and apparatus

A precursor solution adapted to provide a metal oxide film, includes: (a) at least one additive selected from a viscosity enhancer, a base, an acid and a wetting agent; (b) structural promoter ions selected from Mn, Ni, Co, Ir, Ru, Cr, Mo, W, Ta, Nb, V, Mo, Zr, V and Ti ions; and (c) at least one solvent. A method for preparing a metal oxide film includes: (a) providing a substrate; and (b) depositing on the substrate the precursor solution of the invention. Metal oxides films, electrochromic devices containing the films and methods for making them are also disclosed.
