Abstract
The present disclosure discloses a solar cell and methods of fabricating a solar cell. In one aspect, a solar cell includes a substrate, a first doped layer arranged on a first surface of the substrate in a first region of the substrate, and a second doped layer arranged on the first surface of the substrate in a second region of the substrate. The first doped layer includes a first dopant. The second doped layer includes a second dopant. A conductivity type of the second doped layer is opposite to a conductivity type of the first doped layer. The solar cell further includes a third doped layer arranged on the first doped layer. The third doped layer includes the first dopant and the second dopant.
