NOVELTY - The device has a positive electrode comprising a transparent conductive support on which a positive electrode film is deposited. The positive electrode film comprises an n-type semiconductor that is utilized as an active material of the positive electrode, where the n-type semiconductor intercalates and de-intercalates ions of alkaline metal (M1). A nonaqueous liquid electrolyte includes salt of the alkaline metal and organic solvent, where potentials of the positive electrode and a negative electrode are calculated relative to potential of a couple electrode.    USE - Photo rechargeable transparent electrochemical device for use in alkaline batteries i.e. lithium batteries, that are utilized in portable apparatuses. Uses include but are not limited to mobile phone, computer and light tools and heavier apparatuses e.g. two-wheeled transport unit such as bicycles and auto-cycles, and four-wheeled transport unit such as electric cars and hybrid car.    ADVANTAGE - The device achieves high performances during migrating and/or diffusing species and reduces oxidation toward a condenser part in an easy manner.
