Abstract:
1. A method for manufacturing a dye sensitized nanocrystal film comprising the steps of: a) exposing a fluorinated tin oxide (FTO) layer on a surface of a substrate to a flame for a time sufficient to form a layer of crystalline titanium oxide on the FTO layer; and b) after step a), sintering the substrate at a temperature of from about 300 to about 500° C. to form a mesoporous nanocrystalline titanium oxide film, wherein the flame contains a fuel gas and titanium, and wherein during step a), the substrate is rotated about a central axis, and the flame is kept at a constant distance from the surface of the substrate.
