Abstract
A solar cell is discussed. The solar cell includes a substrate having a first conductivity type and made of a crystalline semiconductor; an emitter region having a second conductivity type opposite the first conductivity type, and forming a p-n junction with the substrate; a surface field region having the first conductivity type and being separated from the emitter region; a first electrode connected to the emitter region; and a second electrode connected to the surface field region, wherein at least one of the emitter region and the surface field region includes a plurality of semiconductor portions, and at least one of the plurality of semiconductor portion is a crystalline semiconductor portion.
