Abstract
A solar cell is provided. The solar cell includes a semiconductor substrate. The front surface of the semiconductor substrate has a metal contact area and a non-metal contact area. A first tunneling layer, a first doped polysilicon layer and a first metal electrode are sequentially stacked on the metal contact area. The first metal electrode is electrically connected to the first doped polysilicon layer. A second tunneling layer, a second doped polysilicon layer and a second metal electrode are sequentially stacked on the back surface of the semiconductor substrate.
