MANUFACTURING METHOD

摘要

An embodiment of the invention pertains to a method of making an electrode which comprises a WO3 film, the method comprising the steps of: (a) forming a colloidal solution of a mixture of tungstic acid and at least one organic material, (b) ultrasonically stirring said colloidal solution; (c) applying a layer of said solution to a conductive substrate, and (d) heat­treating the said substrate at a temperature of at least 350°C. Another embodiment of the invention pertains to a method of making an electrode which comprises a WO3 film, the method comprising the steps of: (a) forming a colloidal solution of a mixture of tungstic acid and at least organic material, (b) adding to said mixture a solution comprised of a soluble Lithium salt; (c) applying a layer of said solution to a conductive substrate, and (d) heat­treating the said substrate at a temperature of at least 350°C. An electrode and photoelectrical systems using that electrode are also disclosed in conjunction with methods for making colloidal solutions for use in the aforementioned electrode manufacturing methods.
