A titanium oxide nano tube material is configured so that crystal grains of a nano tube has a crystal structure oriented with the [001] direction of a tetragonal crystal system as a preferred direction. FWHM (Full Width at Half Maximum) of a rocking curve with respect to the (004) plane peak is 11.1 degrees to 20.3 degrees. The titanium oxide nano tube material has excellent photoelectric characteristics since the crystal grains of the nano tube are oriented with the (004) plane or the [001] direction of a tetragonal crystal system as a preferred direction.

A method for manufacturing membrane layers of organic solar cells by roll to roll coating utilizes a roll to roll process for manufacturing an electron transferring layer and an active layer of the organic solar cells is disclosed. The roll to roll process adopted by the method cooperates with a particular solvent and accompanies a parameter control such as temperature and processing time during the sintering and baking steps. The method utilizes a slot-die coating technique in the interim, whereby a membrane layer of the solar cells can be manufactured with a large area for reducing the cost, and the formed membrane layers can have a good efficiency.

The invention provides a nickel-based nickel titanium hydrotalcite film material, a preparation method and application of the nickel-based nickel titanium hydrotalcite film material. The material can be used as a super capacitance material and an electric adsorption material; the nickel-based nickel titanium hydrotalcite film material takes foam nickel as a base material, and a nickel-titanium hydrotalcite film grows in situ on the surface. The film has the advantages of complete crystal shape, uniform density, and high adhesive force, and does not easily fall off. The preparation method comprises the steps of: placing a foam nickel sheet into mixed solution of nickel nitrate and titanous sulfate, and planting the nickel-titanium hydrotalcite film in situ on the foam nickel sheet by controlling the reaction conditions such as pH, a reaction temperature and time. A nickel source disclosed by the nickel-based nickel titanium hydrotalcite film material is from the foam nickel surface and nickel salt dissolved into a solution. Compared with a pure hydrotalcite film deposited on a substrate, the prepared film is stronger in adhesive force on a base body, and the material has a better super capacitive property and an electric adsorption performance, and can be used as a super capacitance electrode material and an electric adsorption electrode material.
