After the frames are glued with the photovoltaic cells, the protruding structures 4 and the groove structures 5 are used for connecting two adjacent photovoltaic cells together, the mutually connected frames are identical in overall dimension, and only when the photovoltaic cells are assembled, one of the frames rotates 180 degrees, so that the protruding structures 4 and the groove structures 5 on the two frames can be just mutually meshed to realize connection. The shape of the protruding structures 31 is obtained through mechanical stress design, and one end of each protruding structure 4 protruding outwards extends along the direction parallel to the substrate 3, so that the spliced photovoltaic cells can bear vertical pressure and horizontal tension.
