NOVELTY - A vanadium-titanium solar cell has light-heat shifting portion and heat-electricity shifting portion connected in parallel. Light-heat shifting portion is formed by mixing tailing of extract of vanadium with ceramic raw material to form a rough palette board, drying, burning board to a vanadium-titanium black porcelain flat plate, separating two parallel flat plates, arranging inlet and outlet channels and a end plate, sealing, solidifying or burning, preheating and vacuum-processing. The heat-electricity shifting portion is formed using strontium titanate as raw material.    USE - Vanadium-titanium solar cell.    ADVANTAGE - The vanadium-titanium solar cell is environmentally-friendly and has high cycle characteristics.    DETAILED DESCRIPTION - A vanadium-titanium solar cell has a light-heat shifting portion and a heat-electricity shifting portion connected in parallel. The light-heat shifting portion is formed by mixing tailing of extract of vanadium (35 wt.%) with ceramic raw material to form a rough palette board with thickness of 3 mm and projected area of more than 0.1 m2 by rolling or dry pressing, after drying, burning board to a vanadium-titanium black porcelain flat plate at 1100 degrees C, separating two parallel flat plates, arranging an inlet and outlet channels and a end plate at two ends, sealing scale-boards at circumference and center with adhesive or bonded material which is burned at temperature less than vanadium-titanium black porcelain, solidifying or burning to get a large-sized vanadium-titanium black porcelain hollow plate, putting glass plate with size slightly larger than hollow plate on a heat resistant concave module to heat, pressing to make glass plate concave downward, preheating hollow plate and placing plate on glass, adjusting temperature and pressure to make the glass plate seal with the hollow plate, and also shaping glass plate and then sealing, and vacuum-processing hollow cavity between glass plate and hollow plate. The heat-electricity shifting portion is formed using strontium titanate as raw material by accurate and ultra thin film method. Small amount of niobium is added to raw material, and free electrons are produced. Niobium oxide is added into hydrofluoric acid, stirred at 75 degrees C, and dissolved completely to form niobium oxide solution. Solution is dropped into ammonia to form white niobium hydroxide precipitate, aged for 5.5 hours, filtered, washed with 3.5% of weak aqueous ammonia, dehydrated, dried in vacuum, dissolved into glycol solution of citric acid at 71 degrees C and stirred to obtain niobium-citric acid glycol solution. Strontium acetate is dissolved in acetic acid to form solution (A). Acetylacetone is dropped with molar ratio of more than 0.95 times of tetravalent titanium cation into butyl titanate, and ethylene glycol monomethyl ether solution is added to form solution (B). Solutions (A,B) are mixed and uniformly stirred, niobium-citric acid glycol solution is added and uniformly stirred to form mixed solution. Glycol and propanetriol are added into mixed solution. The ratio of glycol and propanetriol is 3.5-1. The total concentration of solution is 0.15-0.4 mol/L of bivalent strontium ion. The solution is uniformly stirred to form precursor solution. The precursor solution is coated on uropatagia, pyrolyzed, sintered, produced electronic strontium titanate ultra thin film with thickness of 0.4 mm is clamped between two strontium titanate insulating pieces, and structure with 3-5 layers is formed. Anode output end is connected with a diode, and heat-electricity shifting portion is formed.
