A method for forming a nano-inorganic coating film on a transparent substrate capable of realizing a color

摘要

The present invention relates to a method of forming a fine nano-sized thin film on a cover glass used for a solar power generation module by using a high-functional nano-inorganic composition and implementing various colors. In particular, it relates to a method of forming a nano-inorganic coating film on a transparent substrate such as glass. The high functionality is mainly excellent in mechanical properties including surface hardness and abrasion characteristics, and has very chemically stable characteristics such as water resistance, acid resistance, and alkali resistance. It is composed of inorganic materials and has excellent thermal stability. In addition, depending on the coating method, it is possible to control functions of super-hydrophilic, hydrophilic, and hydrophobic characteristics, and the thin-film coating provides excellent surface contamination and easy-clean characteristics, and optically superior characteristics in terms of light transmittance and light reflectance. Have. By applying the above characteristics generated through the present invention to solar glass, energy conversion efficiency can be dramatically increased, and various color and color can be implemented to express various characteristics of a transparent base material such as glass.
