| description | The invention relates to a solar cell, a photovoltaic module and a preparation method of the solar cell, the solar cell comprises a substrate, a first doped conductive layer, an aluminum diffusion layer and a first electrode, the first doped conductive layer is formed on one side of the substrate, and the aluminum diffusion layer is formed on the other side of the substrate; the aluminum diffusion layer is formed on the side, away from the substrate, of the first doped conductive layer, the aluminum diffusion layer is doped with doping elements and aluminum elements which are the same as those in the first doped conductive layer, and the first electrode is arranged on the side, away from the first doped conductive layer, of the aluminum diffusion layer. The first electrode is electrically connected with the aluminum diffusion layer. According to the structure, the surface barrier of the solar cell can be reduced, so that the contact resistivity between the first electrode and the aluminum diffusion layer is r |
