Abstract
Provided are a solar cell, a manufacturing method thereof, and a photovoltaic module. The solar cell includes: a semiconductor substrate, in which a rear surface of the semiconductor substrate having a first texture structure, the first texture structure includes two or more first substructures at least partially stacked on one another, and in a direction away from the rear surface and perpendicular to the rear surface, a distance between a top surface of an outermost first substructure and a top surface of an adjacent first substructure being less than or equal to 2 μm; a first passivation layer located on a front surface of the semiconductor substrate; a tunnel oxide layer located on the first texture structure; a doped conductive layer located on a surface of the tunnel oxide layer; and a second passivation layer located on a surface of the doped conductive layer.
