PURPOSE: A solar cell with a surface structure for reducing reflectivity and a manufacturing method thereof are provided to maximize photoelectric conversion efficiency by uniformly maintaining the reflectivity of a solar cell regardless of the wavelength of light. CONSTITUTION: A solar cell includes a silicon substrate. The silicon substrate includes a first surface and a second surface to which light is inputted. The second surface is opposite to the first surface. A first surface(101) includes a first opening(1011) and a second opening(1013). The direction of the first opening is inclined to the first surface. |
