Abstract

Provided is a multi-junction solar cell in which two or more absorption layers having different bandgaps are stacked on one another. The multi-junction solar cell includes a first cell including a first absorption layer, and a second cell electrically connected in series onto the first cell, wherein the second cell includes a second absorption layer having a higher bandgap compared to the first absorption layer, and a plurality of recesses penetrating through the second absorption layer.
