Abstract: Provided are a solar cell and a method of manufacturing the same. The solar cell includes a substrate, a first electrode on the substrate, a second electrode on the first electrode, and at least one semiconductor layer interposed between the first and second electrodes, and a first connection layer interposed between the first electrode and the semiconductor layer and electrically connecting the first and second electrodes to each other. The first connection layer includes a plurality of two-dimensional layers vertically extending from a top surface of the first electrode to a bottom surface of the semiconductor layer. The two-dimensional layers include a metal compound.
