Patent ID: 11742453

Abstract:
Provided is a method for manufacturing at least one solar cell, a method for manufacturing a monocrystalline silicon wafer and a photovoltaic module. The method for manufacturing a monocrystalline silicon wafer includes: providing a monocrystalline silicon rod; squaring the monocrystalline silicon rod to form a quasi-square silicon rod with quasi-square cross-section having an arc, a length of the arc being not less than 15 mm; slicing the quasi-square silicon rod to form at least one quasi-square silicon wafer having the arc. The method for manufacturing at least one solar cell includes: using the method described above to obtain a quasi-square silicon wafer having an arc; forming a first solar cell by processing the quasi-square silicon wafer; scribing the first solar cell to obtain a square-shaped sub-solar cell and at least one strip-shaped sub-solar cell. The above methods improve the utilization rate of the monocrystalline silicon rod and reduce production cost.
