Photovoltaic cell, method for manufacturing the same, and photovoltaic module

Abstract

A photovoltaic cell is provided and includes a substrate, having a first surface and a second surface opposite to each other. The first surface includes first regions and second regions alternately arranged in a first direction. The photovoltaic cell includes grooves, located in the substrate at the second regions and recessed into the substrate. A single groove includes a bottom surface, and a side wall connecting the bottom surface to a first region adjacent to the bottom surface. The side wall includes at least one slope inclined towards the first region. The bottom surface is provided as a first textured surface including a plurality of first pyramids, the side wall includes a second textured surface including a plurality of second pyramids, and a single first pyramid of the plurality of first pyramids has a height greater than a height of a single second pyramid of the plurality of second pyramids.
