A small-diameter spheric solar battery cell SS (spheric semiconductor device ) provided with a spheric core material (1), a reflecting film (2) formed on the surface of the material (1), a semiconductor thin film layer (a p-type polycrystalline silicon thin film (4a) and n- diffusion layer (7)) formed in a spheric state on the surface of the film (2), an n+-p junction (8) formed in the semiconductor thin film layer, a passivation film (9), a surface protective film (10) made of a titanium oxide, and a pair of electrodes (11a and 11b) connected to both poles of the junction (8) and a method for manufacturing the cell SS. In addition to the cell SS, a spheric crystal manufacturing device, two kinds of spheric solar battery cells, two kinds of spheric photocatalyst elements, a spheric light emitting element which emits blue visible light, and two kinds of spheric semiconductor device materials are also disclosed. |
