Silicon wafer and preparation method therefor, cell sheet, cell slice, cell string, and photovoltaic module

The invention discloses a silicon wafer and a preparation method therefor, a cell sheet, a cell slice, a cell string, and a photovoltaic module. The monocrystalline silicon wafer comprises a silicon wafer main body and an extension edge that extends outwards from an edge of the silicon wafer main body, the silicon wafer main body is a right-angled square slice or a rounded square slice, the extension edge is a ribbon-shaped structure parallel to the edge of the silicon wafer main body, and the extension edge is used to overlap below the adjacent monocrystalline silicon wafer during welding. By making the extension edge overlap below the adjacent cell sheet or cell slice, a sheet gap is reduced, an increase in an arrangement density of the cell sheets or cell slices is facilitated, and an efficiency of a photovoltaic module is increased. Since the adjacent cell sheet or cell slice shields the extension edge rather than the silicon wafer main body, the area of the cell sheet or cell slice involved in power generation is increased, and an increase in the power of the photovoltaic module is facilitated.
