PURPOSE:To obtain a power source apparatus of energy-storing type, in which photo-energy is stored up electro-chemically and enabled to be taken out when needed, by layer-building and integrating thin-film storage batteries using thin- film solar cell and solid electrolyte. CONSTITUTION:On a metal plate 1 is formed a thin-film storage battery 2 serving as a means of storing up energy, on which an amorphous silicon (a-Si) solar cell 3 is formed, and being followed thereon by a transparent electroconductive film 4 such as ITO or SnO2, and a lattice-shaped electrode 6 serving as one of collectors. Another collector 5 is mounted on a part of the storage battery 2. photovoltaic power produced by light 7 incident from the side of the lattice-shaped electrode 6 is consumed in the external circuit being connected between the collector 5 making contact with a layered positive polar active material which serves as an electrode on P layer side of a-Si solar cell 3, and the metal electrode 6, but otherwise the thin-film storage battery 2 is charged. Similarly electrical energy stored up in the thin-film storage bat tery 2 can be consumed in the external circuit being connected between the collector 5 and metal electrode 6. |
