Abstract

See full text

The solar cell includes a silicon substrate, multiple first electrodes, and multiple second electrodes. The solar cell further includes a tunneling oxide layer, multiple doped polysilicon layers, and at least one barrier layer. The at least one barrier layer is arranged between every adjacent two doped polysilicon layers in the multiple doped polysilicon layers, and the multiple first electrodes are electrically connected to different doped polysilicon layers. The solar cell provided according to the present application can reduce the total thickness of the polycrystalline silicon layer, so that a thinner polycrystalline silicon layer can reduce parasitic absorption, thereby increasing short-circuit current. Moreover, the risk of slurry burning through the tunneling oxide layer is reduced by the barrier layer, while reducing metal recombination, which increases the open circuit voltage of the solar cell, thereby improving the photoelectric conversion efficiency of the solar cell.
