- A solar cell includes a first electrode; a lower light absorption layer disposed on the first electrode; an upper light absorption layer disposed on the lower light absorption layer; and an intermediate reflector layer provided between the lower light absorption layer and the upper light absorption layer, the intermediate reflector layer being comprised of copper oxide. The intermediate reflector layer includes a plurality of copper oxide layers including a lower copper oxide layer making contact with the lower light absorption layer, an upper copper oxide layer making contact with the upper light absorption layer, and an intermediate copper oxide layer provided between the lower copper oxide layer and the upper copper oxide layer. The plurality of copper oxide layers have respective oxygen amounts that gradually increase from the upper copper oxide layer to the lower copper oxide layer.
