PURPOSE: A method for manufacturing a dye-sensitized solar cell is provided to form metal hydride on a semiconductor compound by an immersion method, thereby increasing efficiency of a dye-sensitized solar cell. CONSTITUTION: A film of a semiconductor compound(210) is formed on a transparent electrode. A metal hydride(212) is melted in a solution to produce an immersion solution. A substrate(200) in which a film of the semiconductor compound is formed is immersed in the immersion solution. The metal hydride is coated on a surface of the semiconductor compound. The coated metal hydride is immersed in a dye solution.
Abstract:
PURPOSE: An organic-inorganic hybrid solar cell is provided to simultaneously absorb an infrared ray and a visible ray by forming a p-type semiconductor layer using a p-type chalcogenide system inorganic particle and a p-type conductive polymer material. CONSTITUTION: An organic-inorganic hybrid solar cell comprises a substrate(31), a p-type electrode(32), a n-type electrode, a p-type semiconductor layer, and an n-type semiconductor layer(34). The p-type electrode and the n-type electrode are formed to face the substrate. The p-type semiconductor layer and the n-type semiconductor layer are laminated on a space between the p-type electrode and the n-type electrode. The p-type semiconductor layer is made of a mixture of the p-type chalcogenide compound and the p-type conductive polymer material.
