Abstract

The present disclosure relates to a solar cell and a tandem solar cell. The solar cell includes a substrate, a tunnel dielectric layer, a doped conductive layer and at least one first electrode. A first surface of the substrate includes metallization regions and non-metallization regions. The metallization region is provided with a first texture structure, the first texture structure includes a first recess. The non-metallization region is provided with a second texture structure, the second texture structure includes a second recess. An average one-dimensional size of a bottom surface of the first recess is smaller than an average one-dimensional size of a bottom surface of the second recess. The metallization region includes first regions and second regions, the first regions are arranged at intervals in a first direction, the second regions are connected between adjacent first regions, and the second regions are arranged at intervals in a second direction. The tunnel dielectric layer is arranged on a surface of the first texture structure. The doped conductive layer is arranged on a side of the tunnel dielectric layer away from the substrate. The first electrode includes a plurality of finger electrodes, and the finger electrodes are electrically connected with the doped conductive layer and arranged corresponding to the first regions, so as to facilitate the improvement of the photoelectric conversion efficiency of the solar cell.
