Abstract

PURPOSE:To reduce the cost by attaching an amorphous solar cell panel to a frame made of a thin plate, and by using thus obtained panel board as a blind panel for a construction site or the like. CONSTITUTION:Several solar cell panels each incorporating blind panel 7 composed of a planar frame 9 and an amorphous solar cell panel 11 attached to the frame 9 are supported to a frame 5 formed of steel pipes 3 planted on the ground, so as to form a fence with which a construction side is covered. The amorphous solar cell panel 11 is composed of a substrate serving as a negative electrode and a transparent electrode serving as a positive electrode, an amorphous silicon layer interposed between both electrodes, an upper light- transmissive protecting layer on the transparent electrode, and a lower protecting layer at the lower surface of the substrate. Further, the blind plate 7 can be used for a veranda, a handrail of outside stairs or the like of an apartment or the like. With this arrangement, a solar cell can be simply and inexpensively installed without using a special frame, and inexpensive power generation can be made.

The transparent electrode 17 and the protective layer 21 side is the light receiving surface (front surface) 11A of the amorphous solar cell panel 11, and the stainless steel substrate 13 and the protective layer 19 side is the back surface 11B of the amorphous solar cell panel 11. On the back surface 11B of the amorphous solar cell panel 11, a base layer 23 made of synthetic resin for firmly attaching the amorphous solar cell panel 11 to the flat portion 901 of the frame member 9 is formed. The amorphous solar cell panel 11 has a thickness of 3 mm or less excluding the base layer 23 and has a certain degree of flexibility, and since the base layer 23 also has flexibility, the surface of the plate material is Excellent adhesion to.

Lead wires 25 are connected to the transparent electrode 17 (+ electrode) and the stainless steel substrate 13 (-electrode), respectively, and these lead wires 25 are elements for preventing current backflow, an overcharge prevention circuit, and a storage battery. Connected to a storage circuit consisting of
The electric power generated by the amorphous solar cell panel 11 is stored in the storage battery. The method of using the electric power generated by the amorphous solar cell panel 11 is arbitrary. For example, the electric power is not stored in the storage battery, the direct current is converted from the direct current to the alternating current of 100 V by the inverter circuit, and the commercial power is supplied from the inverter circuit. Alternatively, it may be directly supplied to a DC motor or the like and used to drive it.
