    Abstract: An exemplary embodiment relates to a nano-color coating layer and a method of forming the same, and more particularly, to a color structure representing a back side-reflection color with metallic luster and high chroma when observed in a substrate incident mode by greatly enhancing 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. In addition, the exemplary embodiment provides a color structure which controls metallic luster and texture of a high-chroma color from gloss-semi-gloss-matte texture in various ways by introducing a haze surface structure in which light scattering occurs on at least one surface of the transparent substrate.

    Abstract: A monolithic solar cell includes a first solar cell that is a sequential stack of an electrode, a silicon substrate, and an n-type emitter layer; a recombination layer disposed on the n-type emitter layer; an interfacial layer that is a double layer constituted of PEDOT:PSS and poly-TPD or PEDOT:PSS and PCDTBT, and that is disposed on the recombination layer; and a second solar cell that includes a p-type hole selective layer and a perovskite layer disposed on the p-type hole selective layer, the a p-type hole selective layer contacting and being integrated onto the interfacial layer of the first solar cell in a heat treatment during which the interfacial layer is partially decomposed, wherein the presence of the interfacial layer prevents a reduction in photoelectric conversion efficiency that occurs if the first solar cell and the second solar cell are combined without the presence of the interfacial layer.

    Abstract: A method for preparing a film of a CIS semiconductor compound overcoated by a color layer includes preparing an electrolyte solution by mixing precursors of film constituents including Cu, In, and Se with a solvent; configuring an electrodeposition circuit by connecting an electrochemical cell comprising the electrolyte solution, a working electrode, and a counter electrode to a voltage or current supply device; disposing a photomask having the predetermined pattern on the working electrode; producing the film through the photomask on a surface of the working electrode by applying a reduction voltage or current; disposing a light source to emit light toward the photomask; and photoelectrically depositing the film on the surface of the working electrode at least in the predetermined pattern while illuminating light through the photomask; and forming a color layer of CuSe at least in the predetermined pattern on the film employed as a working electrode using photo-electrodeposition.
