Abstract:
PURPOSE: A method for controlling crystallization for an oxide semiconductor for a solution process at a low temperature is provided to promote crystallization by controlling the thickness of a thin film. CONSTITUTION: A metal oxide precursor solution is coated on a substrate with the thickness of a thin film between 1 and 10 nm. The coated thin film is processed at a temperature of 200 to 350 degrees. The diluted solutions of the metal oxide precursor are made to control the thickness of the thin film between 1 and 10 nm by the coating of the metal oxide precursor solution. The diluted solutions of the metal oxide precursor include the metal oxide precursor of 0.01 to 0.09M.
Abstract:
PURPOSE: A method for manufacturing low temperature water-based copper-indium-gallium-selenium(CuIn_xGa_1-xSe_2) nano particles is provided to control the particle of the copper-indium-gallium-selenium in a nano scale by controlling the size of an intermediate complex. CONSTITUTION: A complex solution containing copper and indium is prepared by reacting a copper compound, an indium compound, and a polymer electrolyte represented by chemical formula 1. A selenium compound is introduced into the complex solution, and copper-indium-(gallium-)selenium nano particles are prepared at low temperature. In chemical formula 1, R1 represents C6 to C30 aryl group, C1 to C18 alkyl group, C2 to C18 alkenyl group, or C3 to C18 cycloalkyl group. R2 is selected from a group including carboxylic acid, sulfonate, sulfate, ester sulfate, and phosphate. M1 is selected from sodium, ammonium, potassium, and amine. n represents an integer of 1 to 1000, and m represents an integer of 1 to 1000.
