Method for manufacturing solar cell

A method for manufacturing solar cell, comprising:

• providing a solar cell substrate;
• forming, by a metallization heat treatment process, a first initial electrode on the solar cell substrate;
• and
• controlling a laser to perform a continuous moving irradiation on the solar cell substrate, and performing a laser-assisted sintering treatment on the first initial electrode to form a first electrode and obtain the solar cell;
• wherein the number of times the laser is controlled to perform the continuous moving irradiation on the solar cell substrate is at least once;
• there is a target irradiation process among all continuous moving irradiation processes, and in the target irradiation process, a moving direction of the laser moving on the solar cell substrate and a longitudinal extension direction of the first electrode intersect with each other, and the moving direction of the laser moving on the solar cell substrate and the longitudinal extension direction of the first electrode are perpendicular to a thickness direction of the solar cell substrate.
