Abstract
A solar cell is provided, including a substrate having a first surface and a second surface, a first dielectric layer formed on the first surface, a first doped polysilicon layer formed on the first dielectric layer, a second dielectric layer formed on the second surface, a second doped polysilicon layer formed on the second dielectric layer, a first passivation layer formed on the first doped polysilicon layer, a second passivation layer formed on the second doped polysilicon layer, first electrodes and second electrodes. The first doped polysilicon layer is doped with an N-type doping element and has a surface having a first roughness, the second doped polysilicon layer is doped with a P-type doping element and has a surface having a second roughness, and the second roughness is less than the first roughness.
