A solar cell includes a back electrode, a single crystal silicon substrate, and a carbon nanotube structure. The single crystal silicon substrate includes an upper surface and a lower surface. The back electrode is located on and electrically connected to the lower surface of the single crystal silicon substrate. The carbon nanotube structure is located on and connected to the upper surface of the single crystal silicon substrate. The carbon nanotube structure includes an upper surface and a lower surface.
