Abstract: The invention relates a thin-film solar cell. In the related art, a buffer layer, a transparent electrode, and a grid electrode are formed on a light absorption layer, but in the invention, the buffer layer and the transparent electrode are not formed on a light absorption layer, and the buffer layer, the transparent electrode, and the grid electrode are formed under a CIGS face such that solar light is directly input to the light absorption layer without obstacles, and the first electrode and the buffer layer are patterned in a saw-toothed structure to engage with each other to reduce a distance by which electrons or holes generated by absorbing light energy move to the electrode or the buffer layer.
