For manufacturing a semiconductor device, such as thin-film solar battery, comprising a base body made of an organic high polymer material, an oxide electrode film and semiconductor thin film each containing at least one kind of group IV elements on the oxide electrode film, one of the semiconductor thin films in contact with the oxide electrode film is stacked by sputtering in a non-reducing atmosphere such as atmosphere not containing hydrogen gas, for example. Thereby, it is ensured that granular products as large as and beyond 3 nm are not contained substantially at the interface between the oxide electrode film and that semiconductor thin film. Therefore, a semiconductor thin film such as amorphous semiconductor thin film can be stacked with enhanced adherence on a plastic substrate having an oxide electrode film like ITO film on its surface.

A method for coating glass, and specifically to a method for manufacturing perfluoroalkoxy copolymer coated glass. The method includes placing a glass substrate on an electrically grounded support and cleaning the substrate with a solvent to remove impurities and prepare the surface of the substrate to be coated. The method also includes coating the surface with a primer and an electro-conductive enhancer, which is uniformly applied to the primer so that the surface of the glass substrate is wet, but not uneven. The method includes powder spraying the perfluoroalkoxy copolymer on the electro-conductive enhancer while the enhancer is still wet. The method includes securing the perfluoroalkoxy copolymer to the glass substrate by evaporating the electro-conductive enhancer.

Large contrast ratio and rapid switching laminated electrochromic (EC) polymer device includes transparent electrode, cathodic EC polymer, gel electrolyte, and counter-electrode. Preferably the cathodic EC polymer is a poly(3,4-propylenedioxythiophene) derivative, PProDOT-Me.sub.2. Counter-electrode is a conductive coating deposited on transparent substrate, with preferred coatings including gold and highly conductive carbon. Lithography and sputtering can be employed to pattern a gold layer, while screen printing can be employed to similarly pattern graphite. Empirical studies of preferred device indicate a color change of high contrast ratio of transmittance (>50% T) is rapidly (0.5-1s) obtained upon applied 2.5V, repeatable to at least 10,000 times, as estimated by electrochemistry. Dual layer EC devices including PProDOT-Me.sub.2 are also disclosed, as are methods for synthesizing preferred EC polymers. Preferred synthesis method for obtaining PProDOT-Me.sub.2 involves refluxing reagents in toluene in the presence of catalyst, while continually removing methanol byproduct from refluxing solution.

A method for coating glass, and specifically for manufacturing perfluoroalkoxy copolymer coated glass and tetrafluoroethylene perfluoromethyl vinyl ether copolymer coated glass. The method includes placing a glass substrate on an electrically grounded support and cleaning it with a solvent to remove impurities and prepare the surface of the substrate to be coated. The method also includes coating the surface with a primer and uniformly applying an electro-conductive enhance to the primer so that the surface of the glass substrate is wet, but not uneven. The method includes powder spraying periluoroalkoxy copolymer or tetrafluoroethylene perfluoromethyl vinyl ether copolymer on the electro-conductive enhancer while the enhancer is still wet. The method also includes securing the perfluoromethyl vinyl ether copolymer to the glass substrate by evaporating the electro-conductive enhance.
