Abstract:
PURPOSE: An organic-inorganic solar cell and a manufacturing method thereof are provided to improve photoelectric conversion efficiency by coating metal hydrate or metal oxide based materials on the surface of a semiconductor compound. CONSTITUTION: A lower plate(180) comprises a first substrate(112), a first electrode(122), a recombination blocking layer(132), a semiconductor layer(134) and a diffraction layer(136). The semiconductor layer includes a semiconductor compound coated with metal oxide or metal hydrate. An upper plate(190) includes an opposite electrode(142), a second electrode(124), and a second substrate(114). A sealing member(152) seals the upper plate and the lower plate. An electrolyte layer(162) is inserted between the upper plate and the lower plate.
Abstract:
PURPOSE: An organic-inorganic hybrid type tandem solar cell and a method of fabricating the same are provided to increase photoelectric conversion efficiency by differently controlling the band gap of a p-type semiconductor compound and the band gap of a hole receptor. CONSTITUTION: In an organic-inorganic hybrid type tandem solar cell and a method of fabricating the same, a p-type semiconductor layer, a first buffer, and a ZnO n-type semiconductor are laminated on a metal electrode to form a chalcogenide group solar cell. A connection layer(106) is formed on the solar cell. A second buffer layer is formed on the connection layer and a single and plurality of thin films to form an organic solar cell. A protective layer(110) is formed on the organic solar cell and a transparent electrode on the protective film.

PURPOSE: An organic-inorganic hybrid solar cell with metal salt and metal carbonate salt and a manufacturing method thereof are provided to improve the efficiency of the solar cell by blocking electrons which are recombined with electrolytes. CONSTITUTION: A semiconductor layer including titanium dioxide is formed on a first electrode(S520). Metal carbonate salt and metal salt are simultaneously formed on the surface of the semiconductor layer(S530). Dye is introduced to the semiconductor layer(S540). A second electrode is formed on the second substrate to face the first electrode(S550). Electrolytes are inputted between the first electrode and the second electrode(S560).
