Abstract
A solar cell comprises a substrate having an opposite first surface and a second surface, and the second surface has a first regions and a second regions adjacent in the first direction; a first passivation layer located on the first surface; a first doped layer and a tunnel oxide layer sequentially stacked in the first region; a first insulating layer located on a surface of the first doped layer away from the substrate; a second passivation layer located in the second region and extending to a surface of the first insulating layer away from the substrate; a second doped layer located on a surface of the second passivation layer away from the substrate, and a second insulating layer located between the second passivation layer and the first doped layer, the tunnel oxide layer in the first direction, a surface of the second insulating layer away from the substrate contacting with the first insulating layer.
