PURPOSE: A solar battery and a manufacturing method thereof are provided to arrange an anti-reflection coating structure by successively laminating a plurality of thin films with different refractive indices, thereby minimizing a surface reflection rate. CONSTITUTION: An n-type semiconductor layer(203) is arranged on a first conductive type substrate(201). A first, second, and third anti-reflection films(204,205,206) are successively laminated on the n-type semiconductor layer. A front surface electrode(207) is arranged in a shape penetrating the first, second, and third anti-reflection films. The front surface electrode is arranged in a structure touching the n-type semiconductor layer. A rear surface electrode(208) is arranged on the rear surface of the substrate. |
