The solar cell includes a substrate (1), a front electrode layer (2), a light absorption layer (3) and a back electrode layer (4) from bottom to top. Before laser structured cutting is performed for the back electrode layer (4), a protective layer (5) is disposed on a surface of the back electrode layer (4), and then laser structured cutting is performed for the back electrode layer (4), or the back electrode layer (4) and the light absorption layer (3) simultaneously through the protective layer (5) to obtain a corresponding structured trench (P3) while the protective layer (5) is kept from being cut by laser, and a material of the protective layer (5) is partially molten due to a localized high temperature generated by the laser processing in a laser structured cutting process and infiltrates into an underlying corresponding structured trench (P3). In this method, at the time of performing laser cutting processing, passivation is performed for newly-processed trench at the same time, reducing production costs, saving processing time. Further, the trench edges after cutting are repaired to improve the morphology of the processed trench, improving the stability of the cell and extending the service life of the cell.
