Abstract

A solar cell includes a back electrode, a silicon substrate, a doped silicon layer and an upper electrode. The back electrode is located on and electrically connected to a lower surface of the silicon substrate. A number of cavities are formed on an upper surface of the silicon substrate. The doped silicon layer is located on the inside surface of the cavities. The upper electrode is located on the upper surface of the silicon substrate. The upper electrode includes a carbon nanotube structure.
