Abstract
According to example embodiments, a solar cell includes a transparent base substrate having a first surface and a second surface opposite the first surface, a first photoelectric layer having a thin film shape on the first surface of the base substrate; and a second photoelectric layer having a thin film shape on the second surface of the base substrate. A bandgap of the second photoelectric layer may be different than a bandgap of the first photoelectric layer.
