  • Patent number: 12615877
    Abstract: The present application relates to a solar cell and a photovoltaic module. In one aspect, a solar cell includes a silicon substrate and a passivation layer. The silicon substrate includes a first surface and an opposite second surface, and a plurality of side surfaces connecting the first surface and the second surface. At least one of the side surfaces includes a plurality of first texture regions and second texture regions. The first texture region includes a plurality of first pyramid structures. The second texture region includes a plurality of second pyramid structures. A structural dimension of the second pyramid structure is greater than a structural dimension of the first pyramid structure. The second texture regions are formed between adjacent first texture regions. The passivation layer covers the first texture regions and the second texture regions of at least one of the side surfaces.
