Abstract
Embodiments of the present disclosure relates to the field of solar cells, and in particular to a solar cell and a production method thereof, and a photovoltaic module. The solar cell includes: a P-type emitter formed on a first surface of an N-type substrate and including a first portion and a second portion, a top surface of the first portion includes first pyramid structures, and a top surface of the second portion includes second pyramid structures whose edges are straight. A transition surface is respectively formed on at least one edge of each first pyramid structure, and each of top surfaces of at least a part of the first pyramid structures includes a spherical or spherical-like substructure. A tunnel layer and a doped conductive layer sequentially formed over a second surface of the N-type substrate. The present disclosure can improve the photoelectric conversion performance of solar cells.
