Abstract: PURPOSE: A hydrophobic sheet and a method for manufacturing the same are provided to simplify manufacturing processes by treating the surfaces of nano structures formed on a substrate using fatty acid. CONSTITUTION: A hydrophobic sheet includes a substrate and nanostructures. The nanostructures are formed on the substrate, and the surfaces of the nanostructures are coated with fatty acid. The water contact angle of the hydrophobic sheet is more than or equal to 70 degrees. The reflectivity of the hydrophobic sheet is lower than that of the substrate in a visible ray range. The permeability of the hydrophobic sheet is higher than that of the substrate in the visible ray range. The hydrophobic sheet blocks light in an ultraviolet ray range.

Abstract: The present invention relates to an eco-friendly quantum dot-sensitive solar cell and a manufacturing method thereof. The solar cell includes: an anode; a counter electrode which is opposite to the anode; and electrolyte which is placed therebetween. The anode includes: nanowires which are arranged in a line on the surface of a substrate; and Ag2S dots which are combined to the surfaces of the nanowires. The existing toxic quantum dots can be replaced with eco-friendly quantum dots. Since the Ag2S dots have a low bandgap of 1.04 eV, it is possible to absorb light of a wide range of wavelengths compared to the existing solar cell, increase efficiency of collecting and delivering electrons using an ZnO nanowire electrode, and improve contact with the electrolyte.

Abstract: A method for preparing ZnO nanobars through a hydrothermal process or lithographic process is provided to produce large-area ZnO nanobars at a low temperature, to allow control of the growth of ZnO nanobars, and to permit alignment of nanobars in a desired position on a substrate. A method for preparing ZnO nanobars comprises the steps of: (a) coating a buffer layer on a substrate; (b) dipping the substrate coated with the buffer layer into an aqueous solution containing a zinc salt and aqueous ammonia; and (c) heating the aqueous solution to grow ZnO nanobars. In a variant, the method for preparing ZnO nanobars comprises the steps of: (1) coating a buffer layer on a substrate; (2) dipping the substrate coated with the buffer layer into an aqueous solution containing a zinc salt and aqueous ammonia; (3) heating the aqueous solution to form a ZnO seed layer; (4) forming a resist layer on the ZnO seed layer; (5) stacking a patterned mask on the resist layer and removing the non-shielded part of the resist layer through etching to provide a patterned substrate; and (6) dipping the patterned substrate into the aqueous solution containing a zinc salt and aqueous ammonia, followed by heating, to grow ZnO nanobars at the portion from which the resist layer is removed.
