abstract |
The invention concerns a method for making an electrode comprising a WO3 film comprising the following successive steps: forming a colloidal solution comprising a mixture produced from tungstic acid and an organic material; depositing on a conductive glass plate a thin film of said solution; performing a heat treatment on said plate at a temperature not less than 350 DEG C. The invention is characterised in that the organic material is selected among ethylene glycol, polyethylene glycol, maltose, glycerol, glucose, mannitol and myo inositol. The invention is applicable in photoelectrochemistry and electrochromism. |
