Solar cell and manufacturing method therefor, and photovoltaic module

A photovoltaic module, comprising:

• at least one cell string formed by connecting a plurality of the solar cells;
• at least one encapsulant film configured to cover a surface of the at least one cell string;
• and
• at least one cover plate configured to cover a surface of the at least one encapsulant film away from the at least one cell string;
• wherein each solar cell of the plurality of the solar cells includes:
• a substrate including a first surface and an opposing second surface, wherein the first surface has a first region and a second region alternately formed along a first direction, and the first region has a first textured surface including a plurality of first pyramids;
• wherein a respective first pyramid of at least some of the plurality of first pyramids includes a main body portion and enclosing portions formed on a lateral surface of the main body portion and stacked in a direction perpendicular to the lateral surface;
• wherein the main body portion is a pyramid-like structure having a plurality of lateral edges, and a lateral surface is between two adjacent lateral edges;
• and
• wherein the main body portion further includes a bottom surface connecting the plurality of lateral surfaces, a respective enclosing portion of the enclosing portions extends toward the bottom surface along a second direction, and includes a respective protruding block at an end of the respective enclosing portion away from the bottom surface and protruding out of an adjacent enclosing portion on a side of the respective enclosing portion away from the main body portion.
