Title:
OPTICAL POWER SOURCE
Document Type and Number:
Japanese Patent JPH0244778
Kind Code:
A
Abstract:
PURPOSE:To implement a compact configuration and high energy density by laminating an optical power source part and a lithium secondary battey using lithium ion conducting type macromolecular electrolyte. CONSTITUTION:GaAs active layers 6, 9 and 12, GaAs light absorbing layers 5, 8 and 11 and AlGaAs window layers 4, 7 and 10 are repeatedly laminated in this order on a metal electrode 13. A transparent electrode 3, a metal electrode 2 and a transparent protecting film 1 are manufactured thereon. A lithium foil 14 is laminated on the rear surface of the metal electrode 13. A laminar V2O5 layer 16 is evaporated on a metal electrode 17 with a polymer electrolyte 15 in a vacuum state. Said element is sealed with a sealing resin 18. Thus a compact configuration and a high energy density are implemented.
