Abstract: A silicon solar cell is provided, including a first silicon layer that absorbing sunlight, a first layer of a structure of photonic crystals formed on the first silicon layer, and a second silicon layer formed on the first layer of a structure of photonic crystals and absorbing sunlight, wherein the first silicon layer and the second silicon layer absorb sunlight at different wavelengths and the first layer of structure of photonic crystals selectively reflects light of a wavelength absorbed by the second silicon layer.

Abstract: Provided are a structure color of photonic crystals in which a new structure of a structure color of photonic crystals is provided so that a nanoimprint process can be performed and mass productivity is improved, a method of manufacturing thereof, and a manufacturing apparatus thereof. The method of manufacturing a structure color of photonic crystals includes: forming a plurality of basic element layers by using nanoimprinting, the plurality of basic element layers comprising a plurality of basic unit bodies each having a symmetrical cross-section and thin film connecting portions connecting the basic unit bodies! sequentially stacking the basic element layers! removing the thin film connecting portions by using etching; and determining whether the structure color of photonic crystals is completed, wherein, when it is determined that the structure color of photonic crystals is not completed, the forming, the stacking, and the removing are repeatedly performed.

Abstract: Disclosed herewith is a diamond film depositing apparatus using microwaves and plasma. The apparatus comprises a rectangular wave guide (125), a mode transition coupler (120), an antenna rod (130), a quartz bell jar (140), a workpiece holder (116), a microwave cavity resonator (112), a source gas inflow ring (160), a mechanical support cylinder (164), a cooling jacket (165), gas inflow and outflow conduits (172 and 174) and a vacuum seal (190). The microwave cavity resonator (112) has a cylindrical shape the diameter of which is decreased in a downward direction. The microwave cavity resonator (112) may have a hemispherical shape, the flat surface of which is oriented upward.
