Abstract: A colored structure representing a back side-reflection color with metallic luster and high chroma when observed in a substrate incident mode greatly enhances light absorbance at a specific wavelength using a resonance structure in which a light absorbing material is inserted between a transparent substrate and an upper mirror layer. The colored structure controls metallic luster and texture of a high-chroma color from gloss-semi-gloss-matte texture in various aesthetic ways including introducing a haze surface structure in which light scattering occurs on at least one surface of the transparent substrate.

Abstract: A method for manufacturing a thin film solar cell includes: depositing a transparent first rear electrode on a first surface of a transparent substrate; depositing a second rear electrode having a high-conductive metal on the first rear electrode; performing a first laser scribing process to separate a double layer of the first and second rear electrodes; depositing a light absorption layer having selenium (Se) or sulfur (S) on the second rear electrode; performing a second laser scribing process by inputting a laser to a second surface of the transparent substrate to separate the light absorption layer; depositing a transparent electrode on the light absorption layer; and performing a third laser scribing process by inputting a laser to the second surface to separate the transparent electrode. Accordingly, patterning may be performed in a substrate-incident laser manner to improve price, productivity and precision of the patterning process.

Abstract: A method for fabricating a nanoantenna array may include forming a resist layer on a substrate, forming a focusing layer having a dielectric microstructure array on the resist layer, diffusing light one-dimensionally in a specific direction by using a linear diffuser, forming an anisotropic pattern on the resist layer by illuminating the light diffused by the linear diffuser on the focusing layer and the resist layer, depositing a material suitable for a plasmonic resonance onto the substrate and the resist layer on which the pattern is formed, and forming a nanoantenna array on the substrate by removing the resist layer and the material deposited on the resist layer. A light diffusing angle by the linear diffuser and a size of the dielectric microstructure are determined based on an aspect ratio of the pattern to be formed.
