Abstract
A tandem solar cell includes a substrate a plurality of sub-cells stacked on the substrate and configured to sequentially perform photoelectric conversion with different wavelength band, and a metal disk array disposed on at least one of interfaces between adjacent sub-cells. A center wavelength of wavelength bands corresponding to the sub-cells gradually decreases as progressing downward with respect to an uppermost layer. The metal disk array reflects a light transmitting a sub-cell disposed over the metal disk array without being absorbed therein. The metal disk array is inserted by means of wafer bonding.
