Method for manufacturing solar cell and solar cell

The invention discloses a method for manufacturing a solar cell and the solar cell. The method for manufacturing the solar cell comprises the following steps that a first conductive type layer is provided, and the first conductive type layer is provided with an upper surface. Dopant is doped into the first conductive type layer so that a second conductive type layer can be formed below the upper surface of the first conductive type layer. The second conductive type layer is provided with a light doping area. Dopant is doped into the light doping area of the second conductive type layer through a laser doping process so that a semiconductor pattern layer can be formed in the light doping area of the second conductive type layer. The concentration of the dopant of the semiconductor pattern layer is larger than that of the dopant in the light doping area of the second conductive type layer.
