Abstract
A back-contact solar cell having a first conductivity-type semiconductor layer in a first region on a back side of a semiconductor substrate, and a second conductivity-type semiconductor layer in a second region and the first region on the back side. In the first region, an intrinsic semiconductor layer and the first and second conductivity-type semiconductor layers are stacked successively on the back side. In the second region, the intrinsic semiconductor layer and the second conductivity-type semiconductor layer are stacked on the back side. In a boundary region between the first and second regions, an insulating layer, and the first and second conductivity-type semiconductor layers, are stacked successively on the back side, with the intrinsic semiconductor layer disposed between the layers and the back side. The insulating layer is interposed between the first conductivity-type semiconductor layer in the first region and the second conductivity-type semiconductor layer in the second region.
