Abstract

A solar cell includes a substrate having a front surface and a back surface disposed opposite to each other; the back surface of the substrate includes a first doped region and a second doped region, and an insulating region; a doped polysilicon passivation contact structure disposed in the first doped region, a doped amorphous silicon structure disposed in the second doped region, and a passivation layer disposed in the insulating region; the doped polysilicon passivation contact structure including a tunneling oxide layer and a doped polysilicon layer; the doped amorphous silicon structure including a doped amorphous silicon layer, and the doped polysilicon layer and the doped amorphous silicon layer having different doping types; wherein the passivation layer is not overlapped with the doped polysilicon passivation contact structure or the doped amorphous silicon structure along a thickness direction of the substrate.
