Disclosed herein is a method for manufacturing a solar cell. The method includes the following steps. A substrate is provided. An article having a plurality of protrusions touches the surface of the substrate and thereby forming a plurality of indentations thereon. Subsequently, a transparent conductive layer is formed on the indented surface of the substrate, a photovoltaic layer is formed on the transparent conductive layer, and then a back electrode is form above the photovoltaic layer.
