摘要： The present invention relates to a dye-sensitized solar cell electrode and a dye-sensitized solar cell including the same. A membrane is formed on a surface of a working electrode, thereby preventing a dye from being separated from an oxide semiconductor layer. The membrane is formed on a surface of a counter electrode, thereby enabling electrolyte elements (I−, I3−, etc.) to be passed therethrough while not allowing the dye to be adsorbed. The reliability and efficiency of a dye-sensitized solar cell be improved.

摘要： The present invention relates to a coating method for preventing warpage of a substrate, and more specifically, to a coating method for preventing substrate warpage comprising forming two or more coating layers by coating the surface of a substrate with coating compositions having different densities, wherein at least one layer of the two or more coating layers is coated and cured with a coating composition containing a silsesquioxane composite polymer represented by a specific chemical formula, thereby not only preventing substrate warpage but also providing high surface hardness, excellent transparency, scratch resistance, water repellent characteristics, anti-fouling characteristics, anti-fingerprint property, thermal stability and gloss characteristics to the surface of the substrate.
