A solar cell, comprising: a substrate (10), comprising a first surface (F), a second surface (S), and a plurality of first side surfaces (C1), the first surface and the second surface being opposite to each other, the plurality of first side surfaces being adjacent to and between the first surface and the second surface, at least the first surface and a portion of the first side surface of the substrate comprising a textured structure (20); a doped conducting layer (30), disposed at least on the first surface and the portion of the first side surface to cover the textured structure; a first passivation layer (40), stacked on the doped conducting layer and covering the first surface and at least the portion of the first side surface, thereby covering at least the doped conducting layer; a passivating contact layer (50), disposed on the second surface; and a second passivation layer (60), stacked on the passivating contact layer and covering the second surface, thereby covering the passivating contact layer wherein the second passivation layer further at least partially covers the first side surface, thereby covering at least a portion of the first passivation layer on the first side surface.
