The present invention relates to an organic electrochemical device and a fabrication method thereof. The organic electrochemical device according to the present invention comprises: a substrate; a first electrode provided on the substrate; an intermediate layer provided on the first electrode; a second electrode provided on the intermediate layer; and a first organic material layer, in which at least a part of the first organic material layer is in contact with the second electrode and the intermediate layer.

Organic electrochemical device, and method for manufacturing same

The present invention relates to a dye-sensitized solar cell and a fabrication method thereof. The dye-sensitized solar cell according to the present invention comprises: a transparent substrate; a porous semiconductor layer provided on the transparent substrate and comprising a dye sensitizer; a current collecting electrode provided on the porous semiconductor layer and deposited such that a structure having at least one through-hole on the porous semiconductor layer is formed; a catalyst electrode; and an electrolyte material provided between the transparent substrate and the catalyst electrode.

Dye-sensitized solar cell and method for manufacturing same

The present invention relates to a method of preparing a photochromic film or plate comprising printing a photochromic substance in the unit of an independent spot on a part or the whole of a basic material and forming a protective layer on the basic material, on which the photochromic substance is coated, so as to protect the photochromic substance. According to the present invention, the photochromic substance is printed in the unit of an independent spot so that the printed unit spots are isolated from each other, thereby prolonging the life of the photochromic substance.

Method for preparing photochromic film or plate

Provided is a spin coating apparatus having a ring-shaped or polygonal auxiliary member for use in manufacture of a coated substrate via spin coating, wherein the auxiliary member is positioned adjacent to the side of a substrate for coating, within a range of a spaced distance of 0.03 to 0.8 mm and a range of a height deviation of less than 0.1 mm, upon mounting the substrate. When a surface of a substrate for coating is spin coated with a coating agent using the apparatus of the present invention, it is possible to eliminate or effectively reduce a ski-jump phenomenon at end portions of a coated substrate occurring when spin coating is performed, thereby resulting in uniform coating of a coating solution on the substrate, and it is also possible to effectively decrease contamination of the substrate for coating due to inflow or stay of the remaining coating agent.

Spin-coating apparatus and coated substrates prepared using the same

There is provided an apparatus for optical disc spin-coating, comprising a cap having a tapered protruding portion or a recess in its central lower portion; a turntable for rotation that has a tapered recess or protruding portion formed in an end of its central axis that is inserted into a center hole of an optical disc, wherein the tapered recess or protruding portion of the turntable is coupled with the tapered protruding portion or recess of the cap in a convexo-concave structure; and a vacuum hole formed in an optical disc support of the turntable. When the cap is eccentrically placed on the optical disc, the cap can be easily attached. In addition, the cap can be easily detached from the optical disc by using vacuum pressure. As a result, the operability and manufacturing efficiency can be increased.
