A solar cell includes a first electrode disposed on a substrate, a first light absorption layer disposed on the first electrode, an interlayer disposed on the first light absorption layer, a second light absorption layer disposed on the interlayer, and a second electrode disposed on the second light absorption layer. The solar cell further includes a groove penetrating through the first light absorption layer, the interlayer, and the second light absorption layer. The groove is filled with the second electrode. The interlayer is spaced apart from the second electrode filling the groove, to define a spacer layer which electrically insulates the interlayer from the second electrode filling the groove.
