Abstract
A solar cell includes a semiconductor base, a first doped semiconductor layer, an insulating layer, a second doped semiconductor layer and a first electrode layer. The semiconductor base has a first doped type. The first doped semiconductor layer, disposed on the semiconductor base, has a doped contact region. The insulating layer is disposed on the first doped semiconductor layer, exposing the doped contact region. The second doped semiconductor layer is disposed on the insulating layer and the doped contact region. The first doped semiconductor layer, the doped contact region and the second doped semiconductor layer have a second doped type, and a dopant concentration of the second doped semiconductor layer is between that of the first doped semiconductor layer and that of the doped contact region. The first electrode layer is disposed corresponding to the doped contact region.
