Title:
SOLAR CELL TREE
Document Type and Number:
Japanese Patent JP3021915
Kind Code:
B2
Abstract:
PURPOSE: To obtain a quasi-tree having a decorative function without requiring any external power by providing many detachable leaflike solar cells to the sides of a trunk support similar to a tree's trunk, storing generated power, and driving a decorative body, illumination means and a sound generator by the power.
CONSTITUTION: A solar cell 5 formed in a shape of a leaf of a tree is formed by adhering three photovoltaic elements 11 formed by coating a soft insulating thin film made of polyimide, etc., with an amorphous silicon thin film to a surface of a leaf-shaped support plate having flexibility such as a punched plate, a lath plate, etc. The one cell 5 generates about 2W. The cell 5 generates when solar light is applied thereto, and its generated power is stored in a storage battery 6 through leads in a trunk support 1. A clock 3 provided at a top of the support 1 is always driven by the power from the battery 6, and a sound generator, illumination means are suitably driven.
